Chain & Sprocket Kit (TBTS) – 15T/38T Drive Set for Bullet Standard 350, Electra & Thunderbird 350 (UCE)

Product Description

This Genuine OEM Kit is engineered to maintain the original gear ratio and ride quality of your 350cc Royal Enfield.The kit includes a precision-machined front sprocket, a heavy-duty rear sprocket, and a pre-stretched drive chain.

Designed for the UCE (Unit Construction Engine) platform, it is the standard fitment for bikes produced between 2010 and 2021. It features a “flower-type” window mounting for the rear sprocket, which is characteristic of the drum-brake and older disc-brake hubs found on the Standard and Electra models.

Key Features:

• Optimized Gearing: Uses the factory 15T/38T ratio to balance low-end torque for city riding and stable cruising speeds.

• High-Carbon Steel: Sprockets are induction-hardened to prevent tooth wear and “hooking” over long distances.

• Weather Resistance: Features a protective coating to prevent rust and corrosion, even in humid environments.

• Quiet Operation: Precision-cut teeth reduce chain “chatter” and mechanical noise for a more refined exhaust-note experience.
