Wiseco 23-24 KTM 250SX-F FC250 81mm Bore 14.5:1 CR 4 Stroke Racer Elite Piston Kit

Wiseco's Racer Elite series forged 2-stroke pistons deliver industry-first 2-stroke piston design and technology to perform in even the most serious racing conditions. These are the first 2-stroke pistons to be forged from 2000 series alloy, providing even greater tensile strength. ArmorPlating surface treatment on the crown, in the ring groove(s), and in the pin bores protects from harmful operating conditions, while Wiseco's proprietary ArmorFit skirt coating conforms to the cylinder bore for optimized fitment and performance. For the serious 2-stroke rider and racer, Racer Elite is the only choice.
