Maybe it need an electro magnetic clutch so it's switchable for wet and dry riding.

Insignificant on a hot dry track but the more slippery it gets the more significant the advantage. Pretty much the same scenario when comparing 2 wheel and all wheel drive race cars / rally cars.

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.

When the markets ready for it and is not so cost consciouis yes, but dont hold your breath. Everything is about economics.

Exactly what i was thinking.

There was a famous quote by someone when 4-wheel drive came into rallying who said....

"with 2-wheel drive with 300hp we were spinning spinning spinning... with 4-wheel drive we were 500hp before we were spinning spinning spinning"

(or something like that)

All about putting the power down...

awesome but is it practical???

Yes.

squid question - would it in theory be able to do two burnouts at the same time ?

**onearmedbandit** · 19th January 2011, 23:08

How do you stop it from going forward dude? With your feet? I don't think you'll have much luck there. Unless you say soak both tyres in oil, then you might get somewhere. Or not.

Simple. Switch the hoses (hooses?) so the front wheel goes backwards, and you hopefully stay approximately stationary.

Now that would be trick.

I have vague recollections of the WR450 and the disadvantages of the 2 wheel drive system. Things like complexity, weight, performance degradation due to heat, suspension action causing variable drive.

It's less complex, lighter and requires less maintenance than a mechanical system, but the difference to a standard bike was quite noticeable apparently.

providing the front wheel provides enough instantaneous torque to overcome the force of kinetic friction of the front wheel, then yes, one could do a rolling burnout, the rear out to be easy enough.

alternatively you could induce slide by braking to get passed the static force of friction, then rolling on the throttle.

oab could do it

or do motorcycle helis! The 4wd rally cars can do em, so no reason why 2wd bikes shouldn't be able to
