WISECO - PK149 - Piston Kit with Gaskets - 64.50 mm - Yamaha YFZ350 Banshee
A piston that fits loose burns oil and loses compression. One that fits tight seizes under heat. The WISECO PK149 is built for your 64.50 mm / Yamaha YFZ350 Banshee engine with the kind of precise dimensional control that sits exactly where it should — delivering clean combustion sealing and smooth cylinder wall contact from the first fire-up. Dedicated forgings and additional lightening operations allow for optimized strength to weight ratio. Designed and built for each specific 2-stroke engine. Riding Style: ATV. Every serious rebuild deserves components engineered to this standard, and the PK149 delivers it.
