It’s built around a 180mm stainless rotor and a compact caliper assembly that fits many Baja Doodle Bug and Blitz models. The package is intended for hobbyists and mechanics who want a tighter feel and more consistent braking performance without a full-frame redesign.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hydraulic kit improve braking compared with the original mechanical setup?\u003c\/h3\u003e\n\u003cp\u003eHydraulic systems transfer force through fluid, which reduces the hand pressure needed to achieve the same stopping power and provides more consistent modulation at the lever. That means quicker response and a firmer feel under load, especially useful on heavier riders or steeper terrain.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHydraulic master cylinder replaces cable pull with fluid actuation for smoother response.\u003c\/li\u003e\n  \u003cli\u003e180mm stainless rotor increases rotor surface area for better heat tolerance and stopping force.\u003c\/li\u003e\n  \u003cli\u003ePre-bled caliper and pads reduce installation time and initial adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich mini bikes and engines will this kit fit?\u003c\/h3\u003e\n\u003cp\u003eThe kit is intended for Baja Doodle Bug, Baja Blitz, DB30 and comparable mini bikes with 97cc, 79cc or 212cc (2.8 HP) engines. It’s not a universal, bolt-on swap for every small bike; some frames require modified mounting points.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible models: Baja Doodle Bug, Blitz, DB30 and many 97cc\/79cc mini bikes.\u003c\/li\u003e\n  \u003cli\u003eEngine compatibility: suitable for 97cc, 79cc, 212cc and 2.8 HP Predator-style engines.\u003c\/li\u003e\n  \u003cli\u003eNote: Not a direct replacement for Coleman CT100U—may need bracket relocation or cutting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the key specs and physical dimensions I should check before buying?\u003c\/h3\u003e\n\u003cp\u003eConfirm the caliper mounting center spacing, handlebar lever perch diameter and hose routing clearances before purchase. These dimensions determine whether the kit bolts up cleanly or if minor frame or bracket changes are required.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCaliper mounting hole center spacing: 45mm (1.77\").\u003c\/li\u003e\n  \u003cli\u003eBrake hose overall length: 1100mm (43.31\") for flexible routing.\u003c\/li\u003e\n  \u003cli\u003eBrake lever perch diameter: 22mm (0.87\"); banjo bolt size: M10x1.25.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is installation and what should I watch for during fitment?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable with basic mini bike maintenance. Tighten handlebar fasteners evenly and avoid over-torquing the lever perch or banjo fittings; incorrect force can damage components or create leaks. If your frame lacks a compatible mounting tab you may need to fabricate or relocate a mount.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for simple clamp-on lever and caliper mounting with existing fork or swingarm tabs.\u003c\/li\u003e\n  \u003cli\u003ePre-installed pads and sealed caliper minimize initial bleeding; verify fluid level and lever travel after fitting.\u003c\/li\u003e\n  \u003cli\u003eUse correct torque values on banjo bolts and handlebar screws; avoid overtightening the lever clamp.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: This FVRITO kit is aimed at mini bike owners who want a clear step-up from cable disc brakes—riders who value stronger stopping power, reduced hand fatigue and better control. It’s a good match for hobbyists, weekend racers and DIY mechanics running Baja Doodle Bug, Blitz, DB30 or similar 97cc–212cc machines who can perform minor frame adjustments if required. If you ride frequently on uneven terrain, carry heavier loads or want more predictable braking, this hydraulic upgrade provides tangible benefits without a full chassis overhaul.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this fit my Baja Doodle Bug without modifications?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits many Baja Doodle Bug and Blitz models, but some frames need mount relocation or minor modification; not a direct CT100U swap.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the kit come pre-bled and ready to install?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The caliper and hose come assembled and typically require minimal bleeding, but check fluid level and lever feel after installation.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"FVRITO","offers":[{"title":"Default Title","offer_id":55168367067479,"sku":"B0CL4SFG2W","price":51.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/fvrito-front-assembly-overview.jpg?v=1790401888","url":"https:\/\/britishgarage.co.uk\/products\/fvrito-hydraulic-disc-brake-kit-for-baja-db30-doodle-bug-180mm-stainless-rotor-pre-bled","provider":"British Garage","version":"1.0","type":"link"}
