Aprilia SL-1000 Drive Force Diagram Discussion

So far, we've only pushed the curves up and down. What else can we do? Not much, unless you start doing engine or transmission work.

This shows a transmission that's been altered to be more close ratio. It would be fun for canyon riding. Maybe harder to get rolling, and not as fast a top speed, but each shift results in a smooth transition to the next gear, with not much discontinuity in acceleration. Racing transmissions are usually close ratio, with tall 100 mph first gears. Unfortunately, this gearbox is not possible in the Falco--gears must work in pairs and these ratios were choosen at random with no concern about being able to fitting the shafts back together.

This bike has a really wide powerband, especially in the midrange. We've also fitted it with an 11,000 rpm rev limiter. This is a pipe dream, but it shows you how a wider powerband can keep you closer to the ultimate force curve longer, resulting in more acceleration.
