I am looking for a replacement clutch for my KFX 450r. I have a trinity power kit on it (full exhaust, intake, and programmer) and want a good replacement clutch similar to the stock one. I see that Tusk makes one that is a really great price. I am considering buying the tusk kit with heavy duty springs. I live in South Carolina and ride mostly in woods but I am really hard on the clutch and ride the clutch all the time. I need a clutch that is going to hold up to lots of abuse. The stock one has lasted a year and I ride very frequently. I was wondering if anyone has tried the Tusk kit or has any other suggestions.
