MV Agusta Brutale 800RR - delicious

I am in no way affiliated with any brands or business mentioned in this post and no commercial contributions have been made. All words and opinions are my own. 

Working away in the office on a Monday like any other, a call comes through to my personal phone.

"Hey mate, it's Vic here from Mid Life Cycles -  an MV Agusta Brutale 800 RR has arrived, you want to come along to the launch day and have a ride?"

--You bet your arse I do.

Fast forward to Saturday morning as I saddle up and point the MT09 towards Kinglake, a mini moto mecca, in the sub alpine hills of Victoria's Yarra Ranges. Eyes aghast with beauty on arrival.


MV Agusta really do build some stunning motorcycles, from their styling, to the exotic materials and high end components - these machines are premium with an impeccable fit and finish. Without a skerrick of mass-production. 

After a meet and greet with Vic and the MV Agusta guys, a bit of paperwork and the rider's brief, I get the key to this lovey one. The Brutale 800 RR.


The baby-faced ride leader - current pro tier racer - took off out of Kinglake at a fun pace, allowing us to toy with the MV's a little more than would be usually accepted on a demo ride. Liberating the throttle allowed a buck eighty plus change when the road opened up with a more consistent dollar fifty five in the corners. 

Allegedly........officer. 
Thank you gentleman. 

As we got into the groove it was obvious that the Brutale 800 RR is more racer than roadster - it is very precise and prefers to be travelling at speed in the top half of the tachometer. The lumpy and hesitant bottom end gave over to a free revving, eager and visceral top end rush.

Start up delivered a familiar, laboured ignition - bringing back memories of past Italian insolence. At idle, the exhaust note was a tad agricultural, however fear not, as the 798cc triple spooled up the noise became like a can full of angry wasps, ready to fcuk you up. 

Beyond the mid range, acceleration is exceptional - speed was added to the digital dashboard in a surprising manner, like - BAM - surprise! The quick-shifter was good, not great and better up than down, although I suspect some of this was user error as it took me a while to force my right hand not to give the throttle a momentary pause when shifting. It works better pinned. 



Handling and chassis characteristics were phenomenal, riding position is quite committed and pitched over, requiring you to grip with your knees to hold your weight - or suffer wrist and shoulder pressure - your choice. 

With minimal rake and weight cantered forward over the nose the Brutale handled magnificently, the bike felt magnetised to the earth. What witchcraft is this? 

Given I was riding an unfamiliar bike I was comfortable attacking corners with more gusto than I had told myself I would. That vibrant chassis buzz when cracking on encouraged more speed towards warp territory - and it felt good, bloody good and bloody stable in doing so. The connection to the bike felt mechanical, which is odd considering all the electronics at play.....I suspected more witchcraft here. 


It was sad to hand the key back, the last thought I had in mind was -- 
'Uh oh I'm not going to be able to stop thinking about you. Scalpel sharp on the road and you made my nuts fizz.' 

I think the Brutale 800 RR deserves a place in the multi bike stable, but it would be a bitch to commute on or for touring. But that's not what it's for.

Looked like an espresso machine - delivered like a drug dealer. 
Hooked?

Pressure Test - Pirelli Angel GT

3,500 Kms is distance enough to form an opinion of a Tyre. The boots in question? Pirelli Angel GT.
Scratch that - not an opinion, an informed and measured assessment. Let's do it. 

Pressure
Tyre pressure is both objective and subjective. 

It is objective in the sense that manufacturer prescribed pressures give a rider a starting point - rightly or wrongly. 

It is subjective in the sense that most riders will disagree with these (usually overly high) prescribed pressures and run their own tyres lower. 



For completeness, both the Yamaha owners' manual and the Pirelli Angel GT specified pressures are Front/Rear (F/R - 36/42)

Where (kgf/cm^2) is the same unit measurement as BAR



Considering the lightweight of the MT-09, F/R 36/42 psi is on the high side, even for Sport Touring tyres such as the Angel GT. 

This will not do. 




I've got a route of approx 250kms planned for a shakedown, a mix of coastal flowing roads into climbing technical with some back road shenanigans peppered throughout. 

Tools for the 'job'
Tools is somewhat of a generous term - all you need is a calibrated Tyre Pressure gauge and a good quality floor pump. I use a Slime digital pressure gauge and my trusty old Lezyne push-bike pump.



Using a digital gauge I can easily calibrate the device as necessary - this however is not essential. If using a mechanical or slide gauge, you may not know its calibration point or accuracy. It may sound strange, but this does not matter too much - as long as you know "F/R 32/34 on my gauge feels right to me" you'll be fine. 

Me? I'm anal retentive and like to know (as much as possible) that my readings have an acceptable error margin and are somewhat close to reality. I setup at F/R 34/36 before hitting the black stuff.


Attitude and performance
Being a Sport Touring tyre - if you're looking for super grippy, soft and sticky boots then you're looking in the wrong place. 

That said, the Angels warm up relatively quickly and offer acceptable grip, albeit with a wooden feel and slow tip in. 

The early morning run along the coast provided a mix of sweepers and tighter cliff-top roads. Conditions were wet and cold, high wind, trivial rain and road spray with some gravel washouts in the corners. 


The Angels gripped well enough, changing direction without duress. On corner exit I was comfortable opening the throttle whilst still pitched over with moderate lean-angle. 

Changing pace I head through back roads on the way to some more technical hills, opportunity enough for wheelies and shenanigans. 


The rear picks up strongly when ripping the throttle to loft the front skyward, the front tyre touching down with immediate grip producing a subtle headshake. No problems here. 

As the roads continue to dry out I push the Angels more - to be fair, dry grip and feel is not great, I would report less feedback and road/rider feel than offered by the Michelin Pilot Road 3s I was running on the Aprilia. Significantly less. 

Climbing into the technical section of the ride, I shift back in the saddle, get my weight over the front, move the balls of my feet to the outside of the pegs, grip the tank with my knees - wrap the throttle - Braaaarp. 


Performing a sighting lap reveals a dry and relatively clean road surface - there are some gravel patches on some of the straight sections but the corners are clear. Game on. 

I get busy running this section of road over the next hour, taking some pressure readings as the tyres warm up. By the end of the 'session' they had picked up ~5+%

Going harder on the Angels is not a linear experience. The attitude of the tyre changes from a slow and neutral tip in,  to a sudden falling into the corners as the front pushes wide. 

On corner exit, the rear does put the Yamaha's power down well and I was relatively confident opening the throttle progressively whilst pitched over. Increase throttle whilst decreasing steering rate.

Findings
The Pirelli Angel GTs offer reasonable wet grip and reasonable dry grip. Unfortunately, the amount of dry grip and feel being sacrificed does not legitimise the wet performance on offer. 

During the early components of the test today the roads were wet, but not excessively. The 3,500 kms travelled so far have seen far worse conditions in heavy rain, as such - the wet performance of this tyre has been demonstrated considerably. 

While exploring the available grip, the overall road/rider feel is wooden with minimal feedback. I have had the rear let go on more than one occasion in hot/dry conditions during the previous kilometres travelled. 

That said, I still managed to give them a good flogging today.


It is important to mention that the MT-09 suspension really is not up to the task of the motor and chassis geometry. Some of the shortfalls I have experienced will no doubt be attributed to these lack-lustre chassis dynamics. 

Which delivers a nice segway to this...........


Stay tuned......

How much Angle can the Angel handle?

Why did I buy a Shiver?


About a year ago I was in the hunt for a new bike……obviously I chose a Shiver.

This choice was not at all by fluke and not without heavy research and deliberation…….I stand by my choice…..the Shiver is a great bike.

The following reviews were posted by me to a well-known Motorcycling forum – given the current BMW F800R test, I felt it was reasonable to add a record of these reviews to the Blog as mark in history as to how I came to own a Shiver.

Enjoy

Bike
Ducati Hypermotard 796



Motor/Throttle/Clutch + Gearbox
The 796 L-twin is a free revving engine which provides usable power and torque from low down.
Vibration was minimal, almost non-existent - at highway speed the power is smooth and quick to react to throttle changes.

The throttle response was as to be expected, not snatchy, not lazy, just right and when paired with a wet slipper clutch the action feels very natural as the clutch pays out with a relatively low friction point.

Handling/Brakes/Suspension
This bike was simply awesome to ride – the front end provided so much grip – it felt welded to the road and was very confidence inspiring.

The brakes and suspension, although not top-shelf, are just right for the bike setup and made sense.

All in all this bike was massively fun to ride, easy to use, and very addictive.

Seat/Comfort
The seating position is obviously very upright giving a clear view of the road ahead and allows you to see through the traffic while filtering and splitting (it would be a weapon as a commuter)

One drawback I see is that the seat is quite narrow and which maybe a problem for longer rides or touring.
__________________________________________________________

Bike
Ducati Hypermotard 1100EVO



Motor/Throttle/Clutch + Gearbox
Unlike the L-twin of the 796 the 1100 was less user friendly. The engine makes lots of torque, which is nice, however it changed the attitude of how the power was delivered. The throttle response was a little snatchy which tended to upset the bikes handling and overall road/rider feel.

Instantly, the EVO felt much more serious, not as fun as the 796. The hydraulic clutch behaved like a pop clutch making the bike lurchy in low speed traffic – the gear box was not as nice as the 796 either, not as tight and I managed to find false neutral between 2 and 3 on more than one occasion.

Handling/Brakes/Suspension
Due to the clutch/transmission set up and the added weight of the 1100 L-twin the handling suffered a little – not too much, but enough to be noticed.

The bike is very stable in a straight line and feels confident on the road – it doesn't change direction as quickly or directly as the 796 – you need to shove this into a corner, the 796 was coerced into a bend almost by telepathy (YES, the 796 was that good!)

The suspension and brakes are a step-up from the 796, again they make sense on the bike – with the added weight and stronger transmission – the suspension and brakes deal with the additional stresses being asked of the bike.

Seat/Comfort
Like the 796 the seating position is upright and comfortable. However the seat itself is much harder and would get pretty tiresome pretty quickly.

If you wanted to go for longer rides you'd really have to change the seat – even the dealer agreed that the race style seat on the EVO is a little serious for a road Hypermotard.

Aprilia Dorsoduro 750




Motor/Throttle/Clutch + Gearbox
First of all – the engine is a donk.

The 750 V-twin makes more power the 796 and only 3hp less than the 95hp of the 1100 Duc – not as much torque as the 1100 but more than the 796 (which is actually an 803cc capacity but remains named as 796 for historical continuity) – so yes, the V-twin of the Aprilia is wonderful.

This is where things went wrong.

The throttle response is very poor indeed. Aprilia use a 3 mode ECU mapping and drive-by-wire technology on the Dorso giving you three choices:

Sport - snatchy and far too aggressive making the bike impolite on the road
Touring – lazy and uninspiring
Rain – don't bother

Essential this bike is a ball-tearer or nothing.....there is no in between which feels right.

As with the EVO1100 the Dorso has a hydraulic wet-clutch. This is a much better setup than the Ducs dry clutch setup – shifting on the Dorso was clean with a short throw and the clutch friction point was not too high, not too low.

Handling/Brakes/Suspension
Being nice and light the bike tips in from the front no problem – it just doesn't behave itself.

Although the suspension was good, it was not good enough to make the bike feel connected to the road. Under compression when cornering the front-end tended to wander a little more than I would have liked – the back was no better – Don't get me wrong, this is not a bad bike by any means and the handling is not poor – it's just not as good as the Ducs or as good as it should be.

The brakes are nice and strong with good solid bite and good feel through both hand and foot controls – no problems here at all.

Seat/Comfort
Again, an upright motard style riding position giving you a clear view of the road and good vision through the corners.

The saddle is actually a little wider than the Ducs and maybe slightly more comfortable – probably still inadequate for lengthy rides or touring without some sort of modification or accessory.

After ride update
I've since found out the Dorso tested was an '09 model with the original fuel map - hence the poor throttle response. Furthermore, this bike had a slow leaking rear tyre which more than obviously accounts for the poor handling exhibited during the test - what a shame.

Triumph Street Triple R



Motor/Throttle/Clutch + Gearbox
First things first – that engine! What a peach!

The in-line 3-cylinder of the Striple is simply intoxicating. The power and torque curves feel superimposed on one another. From down low the familiar triple free revving whistle provides very usable power and torque for low speed traffic filtering making the bike stable – no lurching or surging whatsoever. At highway speed the motor feels even better. In top gear it will pull no problem from 4,000rpm and spool up rapidly......but kick it down into second and the 3cylinder revs like a little Ferrari giving you the most satisfying feeling of torque and power – not to mention ham-fisted wheelie capability!

Did I mention the engine is intoxicating yet?

The throttle is a simple cable setup and feels natural and smooth to use – coupled with a lovely transmission with a positive neutral finder, shifting gear is completed with a satisfying click and positive feedback. The clutch pays out a little higher than I expected but something I got used to immediately then forgot about instantly as it became natural. Validation enough of the setup. I wouldn't change a thing.

Handling/Brakes/Suspension
Considering its test partners, the Striple R is in a league of its own when it comes to handling and road manners. It is mind blowing.

At low speed it is stable, light and nimble – very controllable – as a commuter I really don't think there is a better machine for finding gaps in between cages.

Increase speed and you can feel the race bred frame geometry of the Daytona tap you on the shoulder and say “go on, tip it in.” And tip it in you do. This bike countersteers on a knife edge – the suspension is firm but fair making the bike change direction from the nose like nothing else. Continue to increase speed, the bike remains stable, the suspension soaks up poor road surface and the whole package works in concert.

The brakes are fantastic – a little trail braking and the front stands up before letting the lever out and flicking the nose in another direction. I played a little with hard braking – setup and brake. The bike was well mannered and pulled up hard with linear and predictable deceleration. No complaints here.

Seat/Comfort
Now, this is where I am a little disappointed. It's not that the seating position is bad, it's just not as good as the rest of the bike. I suppose you'd get used to it, but with everything else being spot on I just wish the saddle was too.

My only concern with the seat is for long ride capability and touring. I just can't see either happening with a Striple R – it's a great shame and I hope I am wrong.

Aprilia Shiver Sport 750



Motor/Throttle/Clutch + Gearbox
The Shiver is blessed with the same 750 V-twin as tested in the Dorsoduro – however unlike the Dorso – the Shiver has got it bang on. Very smooth, better fuelling and 3 extra HP to boot!
Output is now 95HP – the same as the 1100EVO.

Again, the Shiver has three throttle modes and drive-by-wire, and again the three choices are the same as the Dorso: 1- Sport, 2-Touring, 3-Rain.

These maps are much better suited and work in tandem with the improved fuelling of the Shiver – I played with both Sport and Touring and they were both vast improvements from their counterparts on the Dorso providing lots of torque and smooth roll on of power. No problems with the throttle.

The gearbox is tight and shifting is short and well indexed. The gearing itself is a little tall – I was cruising at 80-90km/h in 3rd @ ~3,500rpm which makes hi-way miles a breeze – however roll on throttle and there is no hesitation as the V-twin's torques kicks the Shiver along and you GTFO.

The hydraulic wet-clutch is light and very usable with a low friction point – it provides good feel and is well matched to the transmission.

Handling/Brakes/Suspension
At low speed the bike is manageable and nimble hiding what little weight it has well. As speed is increased the Shiver remains extremely stable.

The Shiver has very good road manners. It changes direction wonderfully from the nose and stays online when pitched over. The Sachs upside-down front fork provides good front end grip and feel giving a comfortable and responsive ride.

The brakes are excellent with dual wave rotors and four pot callipers on the front and a single wave rotor, single piston on the rear. Both sets of anchors are given braided brakes lines which accentuates the initial bite and continues with linear and powerful deceleration.

Seat/Comfort
The seating position is upright and relaxed. The bars are wide with a neutral body position – I felt no pressure on my wrist or shoulders and had a clear view of the road ahead as well as the instrument cluster on the dash.

The seat itself was excellent. Nice and wide and very comfortable with a generous pillion shelf. You would be able to complete long distances in the saddle without any accessory or adjustment – from the current suite of bikes tested, the Shiver has the most forthcoming touring capability.

Husqvarna Nuda 900

**I had originally booked a 900R – ohwell.......



Motor/Throttle/Clutch + Gearbox
So what does a bored out BMW F series 800 feel like?

Ride the Nuda 900 and you'll find out! This parallel twin 900 is relatively free revving and very strong indeed. Output is ~105HP and torque is on tap all through the rev range. Vibration is a common trait of parallel twins – however the Nuda has this sorted and vibration was no issue whatsoever.

In sport mode the throttle is quite aggressive and a little snatchy – especially when rolling on in 1st and 2nd gears. Throttle action is much smoother and predicable in touring mode, power is still available on tap and the torque curve seemed to favour the higher rev range, this arrangement makes sense and the bike benefits from it.

Although the gear box was good, albeit with short gearing – the clutch was very heavy with a stiff action – even in the short test it became tiresome. A longer pull-arm on the clutch case side of the cable would help – but as it is, it's not nice.

Gearing is quite short requiring a higher gear at hiway speed to keep RPM at an acceptable level – however the gear box itself is very usable with a clean gear selection, neutral is located no problem.

Handling/Brakes/Suspension
Being a Motard, the seating position if very upright – the seat is quite tall giving you a great view of the road – however I did find that the sky was reflected on the instruments which made them a little hard to read.

Handling was as expected – very nimble, very agile. This bike makes you want to be a bit silly – something I couldn't ignore at one point as I took the shortest path through a roundabout (straight over the top). However, as good as the handling is – I still think the Ducati 796 has it beat, I even felt more connected to the road on the Shiver – the front end of the Husky was a little vague for my liking and can probably be attributed to the lower spec front forks.

Again there are braided brake lines on the dual front rotors and single rear – and again, the brakes are great. Good solid initial bite which continues without fade.

Seat/Comfort
The seat is actually relatively comfortable – I might go as far to say that out of the tested Motards, the Nuda has the best saddle.

The pegs and bars are perfectly positioned – standing up on the pegs over rough ground (and when traversing the roundabout) felt natural and allowed me to control the bike through both the pegs and the bars. Other than the small 12L fuel tank – I think you'd be able to do long rides on the Nuda without an issue.

So that was my journey to buying a Shiver.........after a year of ownership and over 10,000kms I am still enjoying every single moment on my Ape.
