My car (SUV) is a diesel, produces 177bhp and 400nm, weighs around 2000kg, yet is able to hit a top speed of 140mph (on a closed road, of course) and maintain 90mph on a cross continent trip. Now, as far as I can see the S10 produces @90 hp, 125nm, and weighs 270kg. The need for more power means the need for a different machine, because, although riding solo I can cruise comfortably at 90mph and hit 120 mph (via satnav) again on a closed road ::013:: For the life of me I cannot see the use of much more power for road use, I know how much that can cost you!! As EricV said, drop a cog and twist the throttle, the easiest way to increase power and speed.
