WISECO - K1626 - Piston Kit - +0.030” - High Compression - Big Twin 1340 cc 80”
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 WISECO K1626 is a precision-engineered piston kit for +0.030” / High Compression / Big Twin 1340 cc 80” engines, built to hold dimensional tolerances across thousands of heat cycles. Forged from high-silicon aluminum alloy for maximum strength and dependability, giving you the kind of fit-from-day-one accuracy that prevents premature wear on the cylinder wall, wrist pin, and rings. Kit Includes pistons, rings, retainer clips and chrome piston pins. Engine Type: 4-Stroke. Whether you are overboring for more displacement or simply replacing what age and hours have worn out, the K1626 gives you a forged foundation you can trust.
