Description

The TB 143cc Bore Kit is a performance upgrade designed for KLX110 and DRZ110 engines. This kit features a 143cc/60mm big bore with a new performance camshaft to improve airflow and power. It includes a lightweight, high-compression domed piston, a ceramic-coated aluminum cylinder, and a complete head gasket kit.

The ceramic coating on the cylinder reduces friction and improves heat transfer, while the piston offers a 10.9:1 compression ratio suitable for pump gas. This kit requires no machining for installation.
