CILOYU MM80 Mini Bike Hydraulic Disc Brake Kit — 4" Stretch Tabs, Bolt-On Conversion for 80–105cc

The CILOYU MM80 Mini Bike Disc Hydraulics Brake Kit is a bolt-on hydraulic braking conversion with 4" stretch extension tabs that upgrade stopping power and slightly extend wheelbase for improved stability.

This kit is made for MM-B80/MM-B105 style mini bikes and compatible clones, providing a compact hydraulic caliper, mounting hardware and 4" stretch tabs to relocate the rear axle bracket. It replaces cable-operated brakes with hydraulic actuation for stronger, more consistent braking, and the included stretch tabs moderate rear weight distribution for a smoother high-speed feel. Installation requires basic frame modification (cutting and welding the original axle bracket) and is intended for use on flat surfaces after lowering the chassis.

How does this kit improve braking versus the stock cable setup?

Hydraulic systems use fluid pressure to apply force evenly, producing firmer, more progressive stopping than mechanical cables. The CILOYU hydraulic caliper in this kit offers quicker response and greater modulation, especially useful during spirited riding or when heavier loads are present.

• Hydraulic caliper for superior bite and consistent lever feel
• Reduced lever effort compared to cable brakes
• Less fade under repeated braking because of better heat dispersion

What does the 4" stretch extension tab do for the mini bike?

The 4" extension tabs shift the rear axle slightly rearward, lengthening the wheelbase to enhance straight-line stability without overly compromising steering agility. This small change moves the bike’s rear mass distribution, which helps high-speed tracking and reduces twitchiness on flat surfaces.

• Moderate wheelbase increase for improved speed stability
• Slight rear weight shift for a smoother ride at pace
• Designed to maintain original steering range and feel

What modifications are required to install the CILOYU MM80 hydraulic kit?

Installation requires removing or cutting off the stock rear axle bracket and welding the new bracket or stretch tab onto the frame end. This is a permanent frame change — the kit is intended for hydraulic brakes only and the chassis will sit lower after installation, so it suits prepared flat-road use.

• Cut or remove original rear axle bracket
• Weld new bracket or stretch tab to frame end securely
• Install hydraulic caliper, route hose, and bleed system per instructions

Will this kit work with all mini bikes and terrains?

The kit matches a range of 80cc–105cc mini bikes and models listed (Motovox, Monster Moto, Mega Moto, MBX10/11 and similar). Because the chassis is lowered and setup favors hydraulic braking, it’s best used on smooth, flat roads rather than rugged off-road trails.

• Compatible with MM-B80, MM-B105, MBX10, MBX11 and similar frames
• Not recommended for uneven, rocky or highly off-road conditions
• Intended only for hydraulic brake installations, not cable systems

Who is this for? The CILOYU MM80 Mini Bike Disc Hydraulics Brake Kit is aimed at riders who want a robust braking upgrade and modest wheelbase extension for better straight-line stability. It fits owners comfortable with welding and frame modification, and who ride primarily on paved or flat surfaces. If you need stronger, more reliable stopping power and are prepared to make a permanent frame change, this kit provides a compact, high-performance hydraulic solution for compatible mini bikes.
