The WISECO K1735 V-Twin Piston Kit is a forged piston solution designed for performance-focused motorcycle applications. It is manufactured from high-silicon, low-expansion aluminum to provide superior strength, reduced weight, improved heat transfer, and longer service life.
A diamond-turned finish produced on CNC computer-controlled turning centers helps deliver consistent sizing and a precise surface finish. The piston is designed for installation in cylinder bores using cast iron, chrome, Nikasil, or boron composite compositions.
WISECO offers oversize piston options to help extend the service life of cast iron-lined cylinders. Replacement cylinder sleeves can also allow chrome, Nikasil, and boron composite cylinders to be resleeved for WISECO oversize pistons. The WISECO K1735 fits select Harley-Davidson XL1200T SuperLow Touring, XL1200CX Roadster, and XL1200X Forty-Eight models from the listed model years. Verify application details before installation.
