When it came to a top end piston refresh I wanted piece of mind on all parts. Cometics pricy but the absolute best in quality fit and durability.

Nice OEM Quality, at a Great 1 piece Price. Keeps People Riding Affordably. I recommend this Part especially when having to do Constant Clutch maintenance or Replacement Due to Hard Racing.

I love wiseco pistons. They always fit well, they look great (which feel reassuring when doing the top end rebuild). I will always buy wiseco pistons.
