Tusk Clutch Cover Gasket
Daniel in OR
Tusk Clutch Cover Gasket
Seems a little cheaper (thinner?) material than the gaskets from KTM but it fit fine and didn't leak so I'm happy

Tusk Clutch Spring Set
Thomas in AZ
poor investment
Installed tusk comp clutch kit in my kx250f . From the start springs would not hold under full throttle even on dirt. Put factory springs back in with tusk fiber and steel and it works great

Tusk Competition Clutch Kit
Daniel in OR
Tusk Competition Clutch
Replaced my stock clutch with this and it works great. Can't say much for longevity but it's so much cheaper than a replacement from KTM that I'd be happy if it lasts 1/2 as long. I've had good luck with Tusk products before so I'm optimistic that this will be good

PSR Oil Filler Cap Kit
Steve in MI
Best fill plug you can buy
My bike blew my stock filler plug out. I replaced it with one of these, and couldn't be happier. The lock pin keeps the plug from backing out if it ever comes loose, and if it ever does manage to somehow back itself out, I'll never lose my fill plug again. It also looks really nice, and the anodized finish holds up really well. I would recommend one to anybody.
