Model-Year & Chassis Generation Notes
Unrelated to the earlier 660cc single-cylinder MT-03, this 2016–2019 RH07 twin pairs the R3’s 321cc engine with upright bars, 41mm conventional forks, and a single halogen headlight.
Oil & Clutch Mechanical Engineering Note
With zero fairing removal needed to reach spin-on filter HF204, refill 2.1 L w/ filter of SAE 10W-40 JASO MA2 oil and torque the aluminum pan plug gently to 20 N·m.
