Jody in MO
Tusk is Beast
Still going strong in a 2004 660! It's been 4 years of abuse on these and they still feel great! I can't believe the quality. Second to none. Tusk delivered as always!

Wiseco Piston Kit
Lawrence in AZ
Very good piston kit from Wiseco.
I've always had good luck with the Wiseco pro light piston kit for my 2017 YZ250. The price is right and my wife loves the purple velvet piston pouch. Just remember to get the stock piston pin, cause the kit don't come with one. I would recommend this product too others.
