i love my centerforce dual friction, handles a bolt on motor on a 125 shot with ease, its almost lighter than stock and very easy to drive, doesn't even feel like a high performance clutch until you start really pushing it and it doesn't slip not matter what
Try the McLeod street/strip Kevlar. It's a sprung hub single friction stock type clutch that has reasonable pedal effort and can hold a lot of power. It doesn't chatter like the puck clutches either.
