KingCast explains roll on acceleration and the Kawasaki 650R.


Roll-on acceleration is what makes a bike fun to ride without shifting. Many bikes are fast when you wring the snot out of them at upwards of 9, 10, even 14,000 rpm. However, in the Real World it's all about what happens down low and in the midrange. The engineers at Kawasaki have put engine output and gearing together on the 650R so that the midrange is where the Big Hit happens, i.e. 5,000 - 8,500 rpm, to make the most out of 48 ft. lbs. of torque. The results are astonishing: The 650R is not only much quicker than its nemesis, the Suzuki SV650 (I verified this against my friend's SV the other day in traffic) but it is also more spritely in 6th gear than a Yamaha V-Max, a Honda 919 or a Triumph Tiger 955, as noted in Motorcyclist Magazine 60-80 top gear roll-on. And as the license plate suggests.

You get the picture. Miles of smiles :)
