The Royal Enfield Genuine Inner Ratchet (Part No. 110253/A), universally known in the mechanic community as the “Gear Kanghi” (due to its distinct comb-like profile), is a legendary factory-original transmission hardware component. It is engineered exclusively for vintage Royal Enfield Bullet motorcycles featuring the traditional, old-school right-hand side gear shift 4-speed cast iron engine setup.
As verified by the authentic factory packaging label in image_e49f35.png and shown in the precision-stamped layout in image_e49efe.png, this critical indexing plate sits inside the external gear selector box. When you actuate the gear lever, the inner ratchet translates that foot movement into a precise mechanical rotation of the gear selector forks inside the main gearbox casing, allowing the transmission to cleanly lock into your intended gear. Utilizing this genuine OEM replacement part guarantees exact tooth profiles and hardened metallurgy, completely preventing missing gears, loose shifter lever play, or false neutrals common with poorly finished aftermarket parts.
