Honda Rebel & Nighthawk 250's - top speed differences?
« on: January 08, 2014, 07:34:13 AM »
Does anyone know why the same motor supposedly gets the Nighthawk up to 80mph (rated), while the Rebel can only go 70mph (rated)? Is it the carb? Or just that one weighs less than the other?

Nighthawk has more HP.

Yes, but why? Aren't the motors the same?

Is it the Rebel has a single carb? If so that would be a reason, or the main reason. Aerodynamics, weight, gearing.

The Nighthawk has a 37mm carb  (110 main jet) - the Rebel has a 35 (108 main jet).

The cams, the valves, the head, the pistons, the intake - all the same.

Of course the exhaust differs, too.
