Billet Aluminum Drive Sprockets (120s)

  • Olson Brother's precision machined billet aluminum sprockets are ultra light while maintaining strength and long life.

  • We start with light-weight, high-grade aluminum and machine each sprocket to perfection.

  • While almost all our competitors have Chinese stamped sprockets that are typically warped and have non-chamfered teeth that break chain, our sprockets are machined from solid aluminum bar stock to make a perfect sprocket that runs completely true with no wobble and guides the chain onto the teeth without chain binding..

  • For use on all 120cc sleds; #35 or #420/41 chain.

  • Note: All of these sprockets require Olson Brother's billet aluminum sprocket hub.

Aluminum Drive Sprocket, #35        $29.95       

Aluminum Drive Sprocket, #420      $29.95       

OBDi now carries 41 tooth #420 Sprockets!!!

Deluxe Chain Tensioner

  • This chain tensioner is 5" long, 2.2" wide, and 1.7" thick including the roller and bolt. The aluminum plate can be mounted anywhere on the tunnel you choose to place it and it mounted with either two 1/4" bolts or four 3/16" rivets, the choice is yours. Although sprockets are much cheaper to use, we have choosen to use a high quality roller that's 15/16" wide so it's very forgiving no matter where your chain is running and it's one less sprocket you have to shim to be in alignment with the clutch and driven sprockets. The roller has nearly 3" of travel to tension the chain to your preference and is very quickly adjusted.

Gold #420 Chain

  • This chain has a gold coating that not only reduces the friction between the links allowing the chain to move more freely, but also resists heat.

  • Because the chain runs so close to the exhaust on the Arctic Cat and Yamaha 120s, this chain reflects the heat and does not fail prematurely. This is a must have chain for Arctic Cat and Yamahas.

  • Gold on gold finish.

Standard #420/41 Race Chain

  • This is a popular #420 chain that many offroad motorcycles run and have great success with.
