FVRITO 50 Inch Mini Bike Hydraulic Brake Kit for Baja

This hydraulic brake kit is designed to replace the rear mechanical brake on select mini bikes and small-engine models, providing more consistent modulation and greater braking force. It arrives as a complete assembly with a master cylinder, caliper, 1270mm (50") oil hose and mounting hardware. The kit is engineered for trail riding, downhill control and everyday use where improved braking responsiveness is needed.

Which mini bikes will this hydraulic brake kit fit?

The kit is made to fit Baja Doodle Bug / Dirt Bug DB30 models and several small-engine mini bikes including Baja Blitz versions with 97cc, 79cc and 212cc 2.8HP engines when used as a rear brake. Compatibility depends on your bike's mounting geometry and whether the original bracket can be adapted. It is not a universal swap for every model.

• Direct fit: Baja Doodle Bug / Dirt Bug DB30 rear brake
• Works with some Baja Blitz 97cc, 79cc, 212cc mini bikes
• Not a direct replacement for CT100U, Motovox or Mega Moto MMB80/105
• May require bracket modification or relocation for non-matching frames

How much braking improvement should I expect?

Hydraulic systems typically deliver stronger, more progressive braking than mechanical drum or cable-actuated units. Expect firmer feel at the lever, reduced lever travel, and improved heat handling during repeated stops—beneficial on steep descents or heavier loads. Performance gains depend on installation quality and pad condition.

• Smoother modulation and shorter lever travel
• Stronger stopping force compared with stock mechanical brakes
• Better consistency under repeated braking and trail conditions
• Requires correct bleed and secure fittings for peak performance

What are the important size and installation details?

The included oil hose measures 1270mm (50 inches) and the bottom pump mounting pitch is 51mm (2.01 inches). Proper alignment of mounting holes and careful torque on fittings are essential to prevent leaks and ensure safe operation. Minor frame or bracket modification can be necessary on some models to fit the caliper and reservoir securely.

• Hydraulic hose length: 1270mm / 50"
• Bottom pump installation pitch: 51mm (2.01")
• Follow bleeding procedure after installation to remove air
• Avoid over-tightening or under-tightening fluid connections

Are there any fitment cautions or installation tips?

Pay attention to compatibility notes: this kit is not a plug-and-play swap for CT100U, Motovox, Mega Moto MMB80/105 without cutting and relocating the original brake bracket. Always check clearances for the caliper, rotor and hose routing before tightening. Use thread locker on mounting bolts where appropriate and inspect for leaks during initial rides.

• Not direct replacement for CT100U, Megamoto MMB80/105 without bracket changes
• Confirm mounting hole spacing and hose routing prior to final assembly
• Bleed system completely to eliminate spongy feel
• Test at low speed first and recheck fasteners and fluid level

Who this is for: This FVRITO 50" hydraulic rear brake kit is aimed at riders who want a noticeable upgrade from stock mechanical rear brakes on compatible Baja Doodle Bug DB30 and select Baja Blitz mini bikes. It suits DIY mechanics comfortable with basic brake plumbing, caliper mounting and minor frame modifications. If you need a drop-in swap for CT100U or certain Mega Moto models, consider alternate kits or be prepared to fabricate a mounting bracket before purchase.
