on your terms page :
Power Band The RPM range in which the engine creates the peak of its horsepower and torque range.
thats slightly wrong.
The the peak torque range will not be near the peak horsepower range. Especially on these bikes...
haha this reminds me of a conversation I have had hundreds of times before "Hey man, i just got my new bike !" "what kind ?" "Oh I just picked up a CR250, with a powerband !"
