4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Mechanical parent to the Super Cub C125 and Grom 125, adding a helmet-sized underseat U-Box, 5.4 L fuel tank, front disc brake, and 4-speed semi-auto transmission.
Oil & Clutch Mechanical Engineering Note
Honda horizontal underbone with wet centrifugal semi-auto 4-speed clutch—strictly requires JASO MA oil (never JASO MB scooter oil).
