VintCo Engine Piston Kit
VintCo Engine Piston Kits: Precision Parts for Vintage 2-Stroke Engines
When it comes to restoring or rebuilding a vintage two-stroke motorcycle, few components are as critical — or as hard to find — as a properly sized, high-quality piston kit. VintCo has carved out a well-earned reputation as a specialist in this exact niche, offering engine piston kits engineered specifically for the classic machines that defined off-road and motocross riding from the 1960s through the early 1980s.
German-Forged Pistons Built for Demanding Engines
What sets VintCo's piston kits apart from generic aftermarket alternatives starts with the core component itself. VintCo top-end kits include a forged piston made in Germany with an MoS2 coating for break-in — a molybdenum disulfide treatment that reduces friction during those critical first hours of operation and contributes to long-term wear resistance. These forged pistons are known for their durability and strength, capable of handling high compression ratios and extreme temperatures , making them well-suited for the hard-working two-stroke powerplants found in vintage motocross and enduro bikes.
Complete Kits — Everything You Need for a Top-End Rebuild
Each complete top-end kit comes with everything you need to get your rebuild done easily and cost effectively, including a high-quality piston kit (piston, rings, pin, and clips), top-end bearing, and a full top-end gasket kit. This all-in-one approach saves time sourcing individual components and ensures every part works together as a matched assembly. Kits include the piston, ring, piston pin, circlips, and needle cage — specifically adapted to each vehicle for easy and quick installation.
Broad Fitment Across Iconic Vintage Brands
VintCo manufactures new components for 1970–81 two-strokes, drawing on over 25 years of experience in manufacturing replacement parts for vintage motorcycles.

Kits are available in standard bore sizes as well as oversize options — typically offered in 0.5mm, 1.0mm, 1.5mm, and 2.0mm increments — giving builders the flexibility to match a freshly honed or bored cylinder.
