Without seals there is less drag in each link, which is why it is the race choice: more of what the motor makes reaches the rear wheel.\u003c\/p\u003e\u003cp\u003eThe trade is service life. A non-sealed chain needs cleaning and lubing far more often, and it will stretch faster in grit than the sealed MXU version DirtyBike lists alongside it. Chain pitch is 420, chain by RK, sold as a single item at 0.81 lb shipping weight. Verified against the Surron Ultra Bee.\u003c\/p\u003e","brand":"DirtyBike","offers":[{"title":"Default Title","offer_id":54486759309622,"sku":"UB-PC-420-RK-MXZ-48-G","price":34.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0996\/3080\/9398\/files\/Surron-LBX-db-420RK-chain-kit_1d11cd8e-20ca-4466-a93f-c843ae5f9e40.jpg?v=1788105189","url":"https:\/\/motorhabit.com\/products\/dirtybike-surron-ultra-bee-primary-drive-rk-mxz-race-420-replacement-chain","provider":"MotorHabit","version":"1.0","type":"link"}
