Product Info

The Heavy Hitter Super Sprocket w/ Chain Tamer is built specifically for the ETM RTR and RTR Lite, and it’s the first of its kind. Machined from 7075-T6 aluminum with a hard-coated anodized finish, this 73T sprocket is as light as possible without giving up strength, tested on our high-power race bikes and proven not to bend under torque loads.

The real breakthrough is the UHMW-PE Chain Tamer. RTRs running #35 chains are notorious for derailing when chain tension isn’t perfect. Once the chain stretches even slightly, it loosens up, and one derail under throttle is usually enough to snap it. Traditional swingarm-mounted guides don’t work on this bike without modification.

The Chain Tamer acts as a built-in guard around the sprocket with a chamfered inside edge. It keeps slack chains running straight, helps the chain re-seat itself if it starts to walk, and shrugs off debris like rocks and sand that normally knock a chain loose. We’ve intentionally run chains loose during testing, in sand, turns, mud, and the rocky stuff. The Chain Tamer kept the chain on every time.

Built with tough UHMW-PE, the Chain Tamer cushions rock hits, safeguarding your sprocket from bends and costly damage.

If you ride an RTR hard, this is the upgrade that saves chains, saves sprockets, saves rides, and keeps the power down where it belongs.
