A piston that fits loose burns oil and loses compression. One that fits tight seizes under heat. The WISECO 771M05300 is built for your 53.00 mm / Yamaha RT100 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. Designed and built for each specific 2-stroke powersports engine. Forged from high-silicon alloy for maximum strength and dependability. Engine Type: 2-Stroke. Every serious rebuild deserves components engineered to this standard, and the 771M05300 delivers it.
