For a lighter, neater, narrower, and more sensible bike with two front wheels, see these: http://www.quadrovehicles.com/
I didn't watch the video posted here so may be repeating but watched Bike Show on Motors Tv last night and the man from Yamaha said it has 80%! More front grip He said rear grip can be sorted electronically and is on most bikes but there is no way electronics can do anything to improve front grip. So this is Yamahas solution
yeh, Im only telling you how the man from Yam explains its existence. tell him to look at it. Ive seen enough
Yes when he first said it I thought he said 18% Maybe Yamaha say 80 because sceptics wouldn't believe 100% I suppose if he'd said 100% you would rush out to buy one?
