We recommend using a dedicated bearing driver or the \"freeze-and-heat\" method to ensure the bearings drop into the cases perfectly square. Even a slight misalignment during installation can lead to premature failure and increased vibration through the footpegs.\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;\"\u003eYear\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eModel\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;\"\u003e2013-2025\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003e250 RR \/ Race Edition \/ X-Pro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003e2013-2024\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003e300 RR \/ Race Edition \/ RX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003e2015-2024\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eBeta\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003e300 Xtrainer\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 the transmission bearings?\u003c\/b\u003e\u003cbr\u003eA) No, this kit specifically contains the right and left crankshaft main bearings and the necessary outer seals for 2-stroke models.\u003c\/p\u003e\n\u003cp\u003eQ) \u003cb\u003eAre these bearings C3 rated for high-speed use?\u003c\/b\u003e\u003cbr\u003eA) Yes, Moose Offroad precision bearings are designed for high-RPM motocross and off-road applications, meeting Factory Quality standards for clearance and durability.\u003c\/p\u003e\n\u003cdiv class=\"silo-links\"\u003e\n\u003ca href=\"\/search?q=Beta+250+RR+Engine\"\u003eBeta 250 RR Engine Parts\u003c\/a\u003e | \u003ca href=\"\/search?q=Beta+300+RR+Crank\"\u003eBeta 300 RR Crankshaft Parts\u003c\/a\u003e | \u003ca href=\"\/search?q=Moose+Offroad+Bearing\"\u003eShop Moose Offroad Bearings\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003eMoto-House MX – Choice of Champions\u003c\/b\u003e – is located in Clermont\/Montverde, FL.
