Description
If you’re pushing your Honda 250 to the limit, factory pistons won’t cut it. WSM’s +.75 mm piston kit delivers OEM-equivalent quality with engineering upgrades specifically designed to handle higher RPMs, reduce friction, and extend engine life. The MOS2-coated skirts actively dissipate heat while lowering wear—giving you measurable gains in reliability and performance when it matters most.
This is a complete kit per cylinder, so order one for each bore you’re refreshing. Installation is straightforward for anyone comfortable with top-end work, and the improved E-clip design eliminates the common failure point found in stock setups.
