Piston Height Measuring Tool – 500 cc Engines (Dial Indicator Not Included)

The VHM AM34017 piston height measuring tool is a high‑precision workshop instrument designed for use with 500 cc motorcycle engines. Correct piston deck height is critical when fitting performance cylinder heads and inserts, and this tool allows the engine builder or tuner to accurately verify and adjust piston height to secure proper squish and combustion volume. The tool comes with an upper and lower part (for measurement and calibration) and works in combination with a separately purchased dial indicator. It is an essential accessory when installing VHM high‑performance components to ensure exact fitment, optimal combustion geometry and long‑term engine reliability.
