Chain Tensioner with Spring for the Baja MB165 & MB200 Mini Bikes

Keep your Baja MB165 & MB200 mini bike's chain running smoothly with our Chain Tensioner with Spring. Its improved and updated design ensures optimal performance, providing a seamless riding experience. The tensioner is engineered to maintain consistent tension on the chain, reducing slippage and wear, which means fewer maintenance worries and more time on the trails.

The tensioner features a robust 2-5/8" arm and a larger 1-3/4" roller. This combination enhances durability and stability, ensuring that the chain stays aligned and effectively engages with the sprocket. The increased roller size offers better contact, which minimizes the chance of chain derailment even during intense rides.

Baja Motorsports has used several spring designs for their mini bike chain tensioners. This is the "small spring" version. The spring mechanism allows for automatic adjustment to chain slack, accommodating variations in chain length due to changes in tension over time. This ensures your ride remains smooth and efficient, enhancing safety and performance on all your biking adventures.

Note: The arm on this chain tensioner is 2-5/8" long. Older versions were 2-7/8" long. The 2-7/8" chain tensioner can be found at the link below:
