My buddy and I were talking about quads at work. He was trying to tell me that a Powerband is a tube that boosts hp on 2 strokes only. I told him the powerband is the RPM range with most HP and 4 strokes have them too, only they are longer and don't hit as hard (banshee vs. 400ex).

Who is right here.

 

You are.

 

The new kevlar powerbands last longer and boosts power another 3 HP..... ;-)

You're right...
