Royal Enfield Gearbox Ratchet Inner (4-Speed) | 110253/A | Genuine OEM | Bullet / Electra / Machismo

Royal Enfield 110253/A is the RATCHET INNER used in the 4-speed gear-shift/foot control ratchet mechanism on select legacy Royal Enfield models. It plays a key role in positive gear selection—working with the ratchet outer, spring, and related foot-control components to index shifts cleanly. This is a genuine Royal Enfield part as listed by authorized dealer catalogues/microfiche sources. 

If your bike shows symptoms like missed shifts, loose/erratic gear lever feel, or poor return action after years of use, worn ratchet components are a common cause on older 4-speed setups. Replacing the inner ratchet during gearbox/foot-control servicing helps restore crisp engagement and reduces the risk of repeat failures caused by worn mating surfaces.

OEM vs aftermarket: many aftermarket “inner ratchets” vary in machining tolerance and hardness, which can lead to premature wear and inconsistent shifting. OEM-spec is the safer choice for reliability—especially in restoration builds where correct fitment matters.
