DHM High Compression Stock Bore Piston (Gen 2)

The DHM High Compression Stock Bore Piston (Gen 2) is a top-tier component designed for 2014-2020 Grom / Monkey models. Engineered to deliver superior performance, this piston is the highest compression stock bore piston available on the market, offering an impressive 13.2:1 compression ratio for the 52.4mm stock bore. Its unique design includes a high-compression dome that is exclusively crafted for DH Motoring, ensuring unparalleled power output.

Superior Design and Engineering

The DHM Race-spec stock bore piston is the result of extensive testing and development on the racetrack. This ensures that it provides the most power possible from the stock bore. Key features include larger ring and skirt oiling holes, an increased oil spring for enhanced oil volume, and oil ports under the pin holes for continuous wrist pin lubrication. The 360 Degree skirt design increases overall strength, while the racing piston ring kit with pins and circlips guarantees a precise fit. Additional highlights include valve reliefs for up to 27.5/23.5 cylinder head valves, a new base gasket and head gasket, and compatibility with NGK CR9E (6263) spark plug and at least 91 octane fuel.

Optimized Performance and Reliability

Over the past 6 years, DH Motoring has raced and tested over a dozen different stock bore pistons, leveraging this experience to create the most competitive and reliable piston on the market. The piston's design optimizes lubrication, pushing the compression limits for pump fuel, and results in the most refined 125cc piston available. With enlarged oiling holes and deep valve reliefs, the piston maintains optimal lubrication and valve compatibility at all RPMs. This product is a testament to the commitment to performance and reliability that DH Motoring stands for.
