Description
If you’re running a Yamaha XT350 or TT350 and want reliable power gains without compromising engine longevity, a quality piston kit is essential. The Wiseco Piston Kit Standard delivers measurable improvements in combustion efficiency and responsiveness while maintaining the durability needed for serious riding. This is a straightforward upgrade that pays dividends in both performance and peace of mind.
Built from high-silicon aluminum, this piston is engineered to handle the thermal stress of consistent riding. The precision dome geometry optimizes combustion chamber dynamics for improved horsepower and torque delivery across the RPM range. Wiseco’s horizontal slot-pin oiling system minimizes friction losses, which extends engine life and reduces heat buildup—critical factors whether you’re trail riding or pushing harder on the track.
Installation is bolt-on straightforward, and the kit’s tight tolerances ensure a perfect fit without custom fabrication work.
