Genuine Royal Enfield Speedo Drive Assembly (1040741/A) – Meter Pinion for Classic, Bullet & Electra UCE Models

Product Description

Ensure your speedometer remains accurate and steady with the Genuine Royal Enfield Speedo Drive Assembly. Often referred to by mechanics as the “Speedometer Machine” or “Meter Pinion,” this OEM component (Part No: 1040741/A) is the primary mechanical interface located at the front wheel hub.

Designed specifically for the Unit Construction Engine (UCE) range, this assembly consists of high-precision internal gears—a worm gear and a pinion—housed in a durable, weather-resistant casing. Its function is to convert the rotation of the front wheel into a mechanical drive for the speedometer cable. The 1040741/A is engineered with exact gear ratios to match factory tire sizes, preventing the common “needle jump” or “lazy needle” issues caused by worn-out aftermarket alternatives. Whether you’re navigating city traffic or cruising the highway, this genuine drive assembly provides the rugged reliability needed to withstand the vibrations of the 350cc and 500cc singles.

Key Features:

• OEM Precision Gears: Features a factory-calibrated gear set for 100% accurate speed and odometer tracking.

• High-Impact Construction: Built with heavy-duty PVC and metal components to resist road grime, heat, and impact.

• Dust & Moisture Seals: Equipped with internal seals to prevent water ingress, which is the leading cause of gear seizure and cable breakage.

• Direct-Fit Design: A “plug-and-play” replacement that slides onto the front axle and aligns perfectly with the speedometer cable female end.

• Vibration Dampening: Engineered to handle the specific harmonic frequencies of the UCE engine without losing engagement.
