O God here goes...

Contray to the common beleif a 2 stroke will produce far
MORE bottom end power than a 4 stroke if it's tuned for it..
And far more top end power if it's tuned for it... But can not
be tuned for both at the same time.. A 4 stroke can put
out a good amount of both bottom & top end power at thr same time..

And a 2 stroke will rev LOWER than a 4 stroke of the same
cc puting out the same hp.. ( 2t sound as they are reving as they
are fireing twice as often)
Compaire the red lines off the 250 4T GSXR/ZXR/FZR around 17,000rpm
= 8,500 power strokes per minute..
to the 2T KR/TZR/RGV around 12,000 = 12,000 power strokes
per minute.... the 2 strokes are way faster..
