Bloody long straight at an airfield, in the middle of the jungle in Southern thailand. Must have been all the extra oxygen from the trees 'cos I was usually jetted around the mid #170's for normal tracks. Even fast one's rarely saw #180, but at the airfield I was up to #190's.
Must have been perfect conditions. It was pulling just over 13500rpm acording to the (optimistic) MC28 tacho.
Who knows the real truth about factory horse power? Not I. The A kitted RS250 in '98 (was a '97 NSR250 factory engine) put out 91 horse at the wheel. The factory nikes were about 98~100 bacvk then, with the Aprilia the only one over the magic ton, at about 104.
The Aprilia is still far faster than the Honda (poor Dovi), but 120hp may be hoping a little. 110hp is feasible and the rest is down to how much power they have either side of peak I would guess, and of course well developed aerodynamics. I suspect that the graph of the Aprilia RSW250 GP bike would make a stock NSR look peaky!
