CILOYU Mini Bike Brake Lever Kit with 180mm Disc Brake

The CILOYU Mini Bike Brake Lever Kit is a complete rear-disc upgrade for CT100U-style mini bikes, delivering stronger stopping power with a 180 mm steel rotor and a smooth 7/8" lever action.

This kit bundles everything needed to replace or improve the rear braking system on a range of small off-road and recreational bikes that use CT100U-compatible mounting. Designed for riders who want better pedal-to-stopper response than many stock drum or worn-out brakes, the assembly includes the lever, cable, rear caliper, brake pads and a durable 180 mm steel rotor sized for compact frames.

What bikes will this brake kit fit?

The kit is built to match the common fittings of CT100U and several similar mini-bike platforms. It fits 7/8" (22 mm) handlebars and mounts with a 51 mm caliper bolt spacing, making it compatible with many small-frame models.

• Compatible models: Coleman Powersports CT100U, CC100X, Baja Motorsports Doodlebug DB30
• Also fits: Motovox MBX10/MBX11, Monster Moto, Mega Moto, MMB80, MMB105
• Handlebar clamp size: 7/8" (22 mm)
• Caliper mounting hole distance: 51 mm

How does the kit improve stopping performance?

The upgrade switches to a steel disc system with a high-friction pad and a smooth lever pull, which gives quicker response and more consistent braking than many worn stock systems. The exposed rotor design helps heat dissipation and reduces fade on repeated stops.

• 180 mm steel rotor for consistent braking surface and heat resistance
• Pair of replacement brake pads included to restore bite immediately
• Smooth lever travel and 61" cable length for easy routing and leverage
• Rear caliper configuration matches common mini-bike layouts

What are the key dimensions and materials I should know?

Knowing the core measurements helps ensure a bolt-on fit and proper clearance. The kit uses abrasion-resistant cable housing and a sturdy steel rotor designed not to deform under normal use.

• Rotor diameter: 7.08" (180 mm); center hole: 1.45" (37 mm)
• Cable overall length: 61"; sleeve length: 55"; moving length approx. 4.96"
• Handlebar lever bore: 7/8" (22 mm)
• Caliper bolt spacing: 51 mm; construction: steel rotor and durable caliper materials

How easy is installation and what’s included?

The kit is intended for do-it-yourself installation on compatible mini-bikes; basic hand tools and some mechanical experience are helpful. It ships with the principal components required to replace a rear braking assembly, so you won’t need additional major parts for a standard swap.

• Included: 1 x 7/8" brake lever, 1 x 61" brake cable, 1 x rear brake caliper
• Included: 2 x brake pads, 1 x 180 mm disc rotor
• Note: This caliper is configured for rear use—verify front/rear fit before ordering
• Recommended: basic wrenches, thread locker, and minor adjustments after first ride

Who is this for: The CILOYU Mini Bike Brake Lever Kit is aimed at mini-bike owners, maintenance hobbyists, and fleet operators who need a reliable rear disc upgrade for CT100U-style frames. It's well suited for riders replacing worn drum or weak stock brakes and for anyone tuning stopping performance on small dirt or recreational bikes. Verify handlebar clamp size, caliper mounting spacing and rotor clearance on your frame before installation to ensure a correct fit.
