VINTCO - KTA03-1.5 - Top End Piston Kit - 78.50 mm - Maico
Engine rebuilds are only as good as the parts that go back in, and when it comes to the piston — the component under more sustained thermal and mechanical stress than anything else in the top end — there is no room for compromise. The VINTCO KTA03-1.5 is a precision-engineered top end piston kit for 78.50 mm / Maico engines, built to hold dimensional tolerances across thousands of heat cycles. Made with modern materials and manufacturing techniques to ensure an as good or better than OEM fitment and performance, giving you the kind of fit-from-day-one accuracy that prevents premature wear on the cylinder wall, wrist pin, and rings. Pistons are made in Germany and forged for strength and MoS2 (Molybdenum Disulfide) coated to ease break in. Piston Diameter: 78.42 mm. Whether you are overboring for more displacement or simply replacing what age and hours have worn out, the KTA03-1.5 gives you a forged foundation you can trust.
