Cameron says the English writers thought the Moto Guzzi's ability to change direction was down to it's "low centre-of-gravity". You can see why they might have thought that. KC attributes the turning ability to the engine rotating in reverse. Looking at the picture it's possible they are all correct.
The picure also provides evidence of a lost art: flywheel painting.

Back in 5th form physics...(Do they still teach physics in the 5th form these days? Do they have a 5th form?)...the teacher had a bicycle wheel with a handle on each end of the axle. We used to spin the thing pretty fast (another precise technical term) and then try to alter the orientation of the axle. It kicked back pretty hard. Having some familiarity with the steering characteristics of bicycles, I reckon that forces of that magnitude have to have an effect, though I'm ready to believe that what allows you to stay upright has more to do with the trail built into the steering and the lateral forces on the contact patch.

Ah, that bicycle wheel trick is half of an interesting experiment.

So you remember how you could overcome the gyro effect? Yes it was a little difficult (and obviously proportional to the wheel characteristics). Keep this in mind.

Now have a friend sit on a bike and lean over, your job is to hold them up, by the axle.

Which do you think is harder? Hold your friend + bike up by the axle, or over come the gyro force on the wheel spinning?

edit: also, this is just how it was explained to me, that person may have been wrong. I'm open to discussion.

I was always taught the gyroscopic effect of the wheels contributed piss all to the overall stability of the bike, the drive train even less so.

You'd be amazed the diff it makes. Many many years ago, when racing 883's for the first time, I wondered how the top Aussies that came over could go round the sweeper at Manfield at the pace they were (I sure as fuck couldn't). So I sat out one practice session and watched them. Fuck me...they were all leaving the bike in top gear (to keep the revs and crank inertia down), only banging it down a couple on the way out. Once I copied that, I was away. I'd been using the gearbox to try and slow the old girl down,as the brakes were shit. The crank inertia was making the thing go straight ahead.

You can also have the weight too low. Just as Honda did with the fuel tank under the bike, pipes over the top on one of their NSR500's. They become like a Tommy Tippy and you can't get 'em to change direction quickly at all.

Wrong Guzzi - the reputation was earned in the mid 50's by the 350 and 250's. Which had a space frame with the tank only just above the motor...and forks whose mass was centered around the steering axis. Stiff frame,low steering inertia, what was for the time very good suspension and an all up weight which was very very light...All the things we look for now for a quick steering bike. Including the modern buzz word - mass centralisation.

Not surprising they were nearly unbeatable at the time.

Ahhh but will they stand upright when you fall off? Or kick it over in the pits out of frustration?

Meanwhile, Maverick Vinales may be unable to move to Yamaha in 2017 if he gets a podium in 2016, which looks rather likely.

So Yamaha are looking at substitutes for just one year, but what rider (who's any good) wants to come into a factory team for just one year?

Great stuff!

Well in the 90's you'd automatically have said Cadalora...and hoped he'd stay the season...

These days they'd have to beat them off with a stick - there'll be people wanting to do it for free.

Have you tried holding two motorycle wheels (strapped together assumedly) spining at 150kmhr? Otherwise the analogy to a pedly wheel spining at 50 odd is a little lacking...

This works also... https://www.youtube.com/watch?v=MPavvVZUCDg

Cal Crutchlow? He has a 1 year deal with LCR for 2016, and has the option of 2017 too, but he's had more podiums on satellite Yamahas than he has on Ducatis or Hondas.

They may mutually agree it's better for him to try switching camps rather than a third year on Hondas, and that way LCR can hire an alien-in-training too.

[sugilite:Me]

Crashlow should go back to superbikes.

Yeah the last time Yamaha put a Superbike champ on a factory bike it worked out so well...

At least he was the Superbike champ though. Crutchless ain't.

Fuck you are right, I thought he had won WSBK, but only WSS, by the skin of his teeth too.

That said he keeps getting good rides, so there must be something he is good at that we aren't seeing
