Engineered to meet the rigorous demands of off-road and street riding, this kit is the professional solution for maintaining your Beta's braking system. Over time, heat cycles and environmental debris degrade internal seals, leading to fluid leaks or sticking pistons. This comprehensive refresh kit returns your rear caliper to Factory Quality performance at a fraction of the cost of a replacement unit.\u003c\/p\u003e\n\u003cp\u003eEvery kit is specifically curated to include all essential rubber components—such as internal pressure seals and external dust boots—manufactured from premium elastomers that resist swelling and deterioration caused by aggressive brake fluids and high temperatures. Where applicable, the kit also includes replacement brake pins to ensure your pads slide smoothly, preventing uneven wear and rotor overheating. Whether you're racing Hard Enduro or commuting on a Dual-Sport, this kit ensures your Beta remains safe and predictable.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eComplete Hydraulic Refresh:\u003c\/b\u003e Includes all necessary rubber seals, boots, and hardware to rebuild one rear caliper.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh-Grade Materials:\u003c\/b\u003e Seals are engineered to withstand extreme braking temperatures and corrosive DOT fluids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRestores Performance:\u003c\/b\u003e Eliminates piston sticking and fluid leaks for a firm, predictable brake pedal response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDirect OEM Alternative:\u003c\/b\u003e Precision fitment for Beta RR, RS, RR-S, RX, and Xtrainer models across two decades of production.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOff-Road Ready:\u003c\/b\u003e Built to survive the mud, sand, and chemical cleaners common in motocross and trail maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eCleanliness is the most important part of a caliper rebuild. Use a dedicated brake cleaner to remove all oxidation and old fluid residue from the caliper bore before installing the new Moose Offroad seals. We recommend lubricating the new rubber seals with a small amount of fresh DOT 4 brake fluid before seating the piston to prevent tearing or \"rolling\" the seal. After installation, always perform a full system bleed to ensure 100% air-free performance. A properly rebuilt caliper not only stops better but reduces the rolling resistance that can sap horsepower.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eTechnical Specification\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eMounting Position\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRear Caliper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eKit Contents\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eSeals, Dust Boots, and Pins (where applicable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRiding Style\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eOff-Road \/ Street \/ Dual-Sport\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eFitment Range\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eBeta 125cc - 525cc (2005-2024)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eDoes this kit include a new piston?\u003c\/b\u003e\u003cbr\u003eA) No, this is a seal and hardware refresh kit.
