Description
A worn or damaged top-end significantly compromises engine efficiency, power delivery, and longevity. The Wiseco 87mm Piston Kit delivers a complete, matched assembly engineered to restore or exceed OEM performance while handling the extreme thermal and mechanical demands of high-RPM riding. This is a full-system solution—rings, pins, circlips, and gaskets included—so you have everything needed for a professional-grade rebuild in one box.
Wiseco’s high-silicone forged construction minimizes thermal expansion, maintaining precise ring-to-bore clearance even under sustained heat. This dimensional stability translates directly to better compression, reduced blow-by, and improved fuel efficiency. Because these pistons are engineered as a complete system, using only Wiseco rings ensures optimal performance and eliminates the guesswork of aftermarket compatibility.
