TMX125alpha is equipped with the newly-developed legendary Overhead Valve (OHV) engine which was exclusively made for this model and for the Filipino market. This OHV engine uses a push rod to deliver a balance of acceleration and control for hours of easy and hassle-free tricycle and business operations while still being fuel efficient at 58.0km/L. Honda 3S shops nationwide are already familiar with the OHV engine, which also has readily available spare parts, making maintenance easy and convenient.
