YUMINASHI #415 SUPERLIGHT RACING SPROCKET & CHAIN CONVERSION
Fits Honda NBC110 / C110 Super Cub Postie Bikes (JA23E Engine) (2013 – 2017)

Unlock hidden power on your Australian Honda NBC110 / C110 Postie Bike with the Yuminashi #415 Superlight Racing Drive System. Factory drive setups create heavy rotational drag on the 109cc engine, sapping precious top speed and throttle response. Converting to a narrow #415 ultra-lightweight racing chain and high-precision sprocket kit slashes unsprung rotating mass to send maximum usable power straight to the rear wheel.

• Friction & Drag Reduction: Ultra-thin #415 pitch significantly decreases drivetrain friction compared to heavier stock drive setups.

• Faster Acceleration & Rev Response: Reduced rotating weight allows the JA23E single-cylinder engine to spin up quicker out of turns and pull harder at higher RPMs.

• Targeted for Postie Bike Performance: The essential drivetrain upgrade for Postie Bike racing, endurance events, and high-output tuned builds across Australia.

Note: #415 chains must be installed with matching Yuminashi #415 front and rear sprockets. Do not mix with standard #420 or #428 pitch components.
