This page lists chain tensioners, tensioner springs and chain adjusters for electric scooters, dirt bikes, go-karts, ride-ons and mini bikes. We carry Razor tensioners for the MX350 and MX400 (W15128050079), MX500, MX650, SX500 and RSF650 (W15128190079), E300, E100 and E150, Pocket Mod, Dirt Quad, Dune Buggy, Crazy Cart and Crazy Cart XL, Ground Force Drifter, PowerRider 360, EcoSmart Metro and Trikke E2. Other fitments include the Baja MB165 and MB200 (165-063), Baja Doodle Bug (DB30R-153), Monster Moto / Mega Moto Classic 105cc and MM-B80, Motovox MBX10, Hiboy DK1, Pulse, Swagtron EB5 and Hyper HPR 350, plus universal ATV and dirt bike chain adjusters and rear axle tension adjusters.

Most tensioners are model-specific, and some Razor parts are listed by version number (for example E300 versions 36+ or Crazy Cart versions 1 - 5), so check the version of your scooter before ordering. If only the spring is worn, replacement springs and the M6-1.0 screw and nut are sold separately. For other drive parts, see Recreational Scooter Parts. Can't find your part? Contact us with your model and a photo of the old part, and we'll help track it down.
