That'd be awesome for rescuing stoppies that are over the balance point.

Interesting idea. I wonder if this affects how much acceleration is required to lift the front wheel given that a certain percentage of the acceleration will be done by the front wheels.

There must be some slip in the hydraulic pump/motor combination (may not be depending on the kind of pump) otherwise I could see it causing the same problems you would get with a solid rear axle on a car...

Just something else to break on the R1's

No front-wheel skid when you're setting down a long wheelie either...

I can't help but wondering that if it made that much difference then why aren't we seeing lots of race bikes come out with this idea fitted to them?

[cowboyz]

not being a really bright spark here but picking it makes a bigger difference if the front is actually touching the ground.

I wonder how the feel changes. I kinda get the feeling that the frotn would feel like its tucking under in the tight stuff being pulled round.

It could be that it isn't allowed? I don't know and I'm not going to look it up but it certainly sounds like the kind of thing that could be de-facto restricted...

It had to come and now the 'super safe' flood gates have been opened what else is there to follow?

Limited slip diff and Traction control will stop your wheels spinning.

ABS will stop you over braking.

And the final nail in the coffin for needing skill to ride a motorcycle will be Electronic Stability Control.

I suppose pop out little wheels to stop you falling over will be a little further down the line.

I'm not 100% certain of the details, but a few years ago a Yamaha (I think Tenere, something like that) converted to the same system got 4th place (in it's class) in the "Paris to Dakar" rally.

I'm fairly certain that they released that Model Yamaha (2 wheel drive) in the UK and they sold (slowly), but didn't make them again.

one google search, and here it is, (it was a WR 450)

Getting that past the regulatory bodies would be impossible, they dont like progress e.g electronic aided suspension is currently outlawed in WSBK etc. The wet track they rode it on is Karlskoga, about 2 and a half hours south of Stockholm. I went to that track about 5 years ago when that bike was in its infancy. In the wet that bike was nearly 4 seconds a lap faster than an identical but rear wheel drive only R1. This with Anders Andersson aboard who has done tens of thousands of test laps on that circuit and is inch perfect every lap

Would be interesting to know the difference in lap times between rear and two wheel drive in the dry...
Maybe it need an electro magnetic clutch so it's switchable for wet and dry riding.

I imagine with front wheel drive you will have more control on the front wheel.. As well as backing it in maybe eventually we will see top sports bikers 'fronting it out'

I think a live diff/speed difference control would be the only way to make it really work though. Even if it is electronically aided.

I could actually see two wheel drive being of benefit to the likes of FJR/Concours/ST style of bikes and perhaps commuters too. Bikes that are made for riding big distances through all sorts of weather and your everyday drag it out and go to work type bikes.
