RZEOZU Mini Bike Throttle and Brake Kit for MMB80/CT100U — 50" Adjustable Throttle & 61" Brake Cable

RZEOZU’s kit is a complete replacement throttle and rear brake assembly engineered to fit Mega Moto MMB80, Coleman CT100U and similar 50–100cc mini bikes.

This all-in-one set bundles a rear brake caliper with a 61" brake cable, a 50" adjustable throttle cable, a silver-plated 7/8" (22 mm) brake lever and a pair of 22 mm handlebar grips so you can restore control and throttle response quickly. Each component is matched to common mini-bike frames and engines used on Monster Moto, Coleman and Baja models, making it a convenient repair or upgrade pack when original cables or levers are worn, frayed or corroded.

What exactly is included and why does it matter?

The kit arrives with every external control piece needed to replace a rear braking system and handlebar throttle on many 50–100cc mini bikes. Using matched parts helps ensure cable routing, lever reach and mount compatibility work together without improvisation.

• Rear brake caliper sized for common mini-bike rear hubs and mounts.
• 61" brake cable to reach typical frame routing and add adjustability.
• 50" throttle cable to fit from the right-side throttle to the carburetor.
• Silver-plated 7/8" brake lever and a pair of 22 mm rubber grips.

How does the adjustable throttle cable influence ride control?

The 50" throttle cable offers enough length and adjustment to fine-tune throttle sensitivity and idle behavior. Adjusting cable tension alters response at the twist grip; loosen for smoother idle, tighten for crisper throttle engagement.

• Adjustable length for varied frame and engine placements.
• Pre-measured 50" length fits most mini bike throttle routes without modification.
• Improved responsiveness when tensioned correctly; avoid over-tightening.

Will the rear brake caliper and 61" cable provide reliable stopping power?

The rear caliper is designed to deliver precise braking force for typical mini-bike use when paired with the included 61" cable and lever. Proper installation and periodic cable adjustment keep braking predictable across different riding conditions.

• Caliper sized for commonly used rear wheel mounts on MMB80 and similar models.
• 61" cable length accommodates neat routing and future adjustment.
• Silver-plated lever resists corrosion and maintains lever feel.

Which models and engines is this kit compatible with?

This set was developed to fit a range of mini-bike models and common small engines; compatibility covers several Monster Moto, Coleman, Baja and Motovox minibikes powered by 79–100cc engines. Confirm measurements with your frame before ordering.
