HP Torque, Weight etc

[Tev62]

Power = (2*Pi*N*T)/60.

Where N= RPM /60 to get revs per second.
T=Torque

This formulae stands for a given rev value of course but it does highlight the simple relationship (in formulae form) of Torque and Power.

A common strategy of motorcycle manufacturers is to lighten up engine components, pistons, con rods, valve train, etc. and just increase the maximum red line with little real torque increase. Then they shout from the rooftops about how much extra power they have over their competitors. But given most riders do not sit at 11,000RPM most will never see that extra power. Now if a manufacturer can increase his torque lower down the rev range we can all feel that and possibly use it, especially on heavier motorcycles.
