Motorcycle Bicycle Chain Tensioner With 4mm Thick Adjustable Steel Bracket

This universal chain tensioner kit is an essential upgrade part for most 79cc to 212cc mini bikes, solving loose chain, slipping and falling-off issues during riding.

The bracket is made of 4mm thick solid steel with anti-rust black coating, hard to bend or deform under long-term vibration. The built-in precision bearing roller runs ultra-smoothly, greatly cutting friction between roller and chain, reducing abnormal noise and wear.

Slotted long holes and stepped serrated structure support infinite front and back adjustment. You can fine-tune chain tightness freely to keep the chain straight all the time, avoid chain derailment, jump gear and abnormal abrasion of sprocket.

Wide compatibility covers mainstream mini bike models including CT100U, CC100X, MBX10, CT200U, BT200X and engines Predator 79cc, 212cc, GX160, GX200. Simple bolt-on installation without complicated modification, the installation diagram guides you to finish assembly quickly.

Without this tensioner, loose chains will hit frame, wear out fast and even break suddenly on rough roads. After installation, stable transmission improves riding safety, lowers maintenance frequency and effectively extends chain and sprocket service life.

Ideal for off-road enthusiasts, DIY rebuilders and mini bike owners, durable metal construction brings long-lasting performance for daily and off-road use
