The Problem on the Stark is not lack of torque, but the ability of the driver to transform the usable torque into movement.

BTW you can also change the sprocket on a Stark. But it makes no sense due to overall much more usable torque.

So when you need max torque (heavy terrain) the 450 just gives you a very small band, you have to keep by extensively using the clutch...

So with double as much torque in any rpm, you can build a secondary gearing that gives you double as much speed at the same torque.

But you realize that you made the usable power band of the 450 so small, that it is useless?

Up to 8K rpm the Stark will give you double as much torque over the complete rpm range as the 450 does.

Awfully close only for a very small band of rpm. And you cannot use it without using the clutch. Or your wheel will turn wild without...

Stark has nearly the same gearing as other bikes. But the ICE engine has only 1/10 of the torque at low speed. And you are not able to...
