Parts for the 2001 to 2008 Suzuki RM125 chassis, the donor platform for the Heavy Hitter RM e-moto conversion. The conversion mounts put a QS138 70H V3 motor output shaft in the stock position so the build can run a 520 front sprocket with the original rear sprocket and chain, without modifying the frame or its mounting points. This page pairs RM-specific parts with our universal E-MX range: grips, tires and tubes, chains, displays, throttles and maintenance gear.
The conversion mounts and the RM-specific brake, bearing and spring parts come and go with availability, so check this page or contact us if you are planning a build.
