XIKOBY Mini Bike Hydraulic Brake Kit + 7/8" Throttle for Baja DB30 Doodle Bug — 180mm Disc, 50" Hose

XIKOBY's mini bike hydraulic brake kit and 7/8" throttle assembly upgrade the braking and throttle control on Baja DB30, Doodle Bug and similar 97cc/79cc minibikes.

This replacement kit bundles a hydraulic front brake system with a 7/8" throttle grip and switch assembly designed for small-displacement minibikes using a single 180mm rear disc configuration. Built to improve stopping power, reduce lever effort and refresh worn control parts, the package includes rotor, caliper, hose, brake pads, throttle cable and mounting hardware. Read on to learn fit details, installation notes and what to expect from performance and compatibility.

How will the hydraulic brake change my stopping performance?

The hydraulic brake provides stronger and more consistent braking compared with a mechanical cable system, giving you smoother modulation and shorter stopping distances under normal riding conditions. The lever requires less hand force, letting you brake precisely even with two fingers.

• 180mm stainless steel disc for high heat dispersion and quieter operation
• Two brake pads included for immediate use
• Hydraulic caliper and 50" hose for responsive braking
• Reduced lever effort for improved control on trails and flats

Which minibikes and engines are compatible with this kit?

The kit is made to fit many Baja DB30, Doodle Bug and Blitz style minibikes that use 97cc, 79cc or similar 2.8HP Predator-style engines and a single 180mm disc brake setup. It is not a universal drop-in for every model; some frames or mounts may require modification.

• Compatible: Baja DB30, Doodle Bug, Blitz mini bikes with 97cc/79cc/2.8HP engines
• Hose length: 50 inches tailored for DB30-series routing
• Note: Not direct replacement for Coleman CT100U without relocating brake mount
• Includes mounting screws, flange screws and necessary small parts

What comes in the box and what tools are needed for installation?

The package supplies the main brake and throttle components plus small hardware so you can complete most installs with basic tools. A wrench is included for convenience, but you may need additional hand tools and time to trim or reposition mounts depending on your bike.

• Included: 7/8" left handlebar throttle, 50" brake hose, 180mm rotor and caliper
• Also: 2 brake pads, 6 flange screws, 2 screws, 6 cable ties and an ON/OFF start switch
• Throttle: 50" throttle cable and clamp for standard handlebar fit
• Tools: basic wrenches, possible drilling or relocation hardware if frame differs

Will I need to bleed the brake or adjust the throttle after fitting?

Yes—after mounting the caliper and connecting the hose you should bleed the hydraulic line to remove air and ensure consistent lever feel. Throttle cable routing and clamp tightening should be checked for smooth operation and full return travel to avoid sticking.

• Brake bleeding recommended for firm, responsive lever action
• Verify hose and cable routing for no binding or sharp bends
• Adjust lever reach and throttle play for rider comfort and safety

Who is this for: Riders or mechanics upgrading older minibikes or replacing worn controls on Baja DB30/Doodle Bug/Blitz models who want a stronger, smoother hydraulic brake and a reliable 7/8" throttle assembly. It's ideal for recreational trail riders, backyard racers and anyone restoring a small-displacement minibike where fitter routing and minor mount adjustments are acceptable. If your bike uses a different mount geometry (for example certain Coleman models), plan for additional modification before purchase.
