Universal chain tensioner for minibikes/pocketbikes, adjustable chain support, suitable for 47cc/49cc/110cc off-road minibikes and other small bicycles.

【Designed for Mini Models】 The GOOFIT chain tensioner is specifically designed for mini motorcycles, pocket bikes, small off-road vehicles, and go-karts with 47cc, 49cc, and 110cc engines. Its compact size and adjustable design fit perfectly within the limited space of these small vehicles' chassis, solving common problems like chain slack and slippage.

【High-Strength Nylon and Alloy Construction】 The main body is injection-molded from high-strength, wear-resistant nylon, making it lightweight and corrosion-resistant.

The main support components and adjustment screws are made of a metal alloy, ensuring the robustness and durability of the overall construction, even in rough terrain, thus guaranteeing reliable chain guidance and support. The innovative design of the adjustable chain guide (slider) allows for precise control of chain slack with a simple tool. As the chain stretches over time, it can be easily readjusted to ensure optimal power transmission and extend the lifespan of the chain and sprockets. [Easy Installation, Universal Compatibility] This versatile chain tensioner is typically mounted using brackets and slotted holes and is compatible with various mounting points on minibike frames. Installation is simple and can usually be done with standard tools, making it a practical modification for improving the reliability of small vehicle transmissions. **[Effective Protection Against Chain Jump-Off and Noise]** By applying consistent holding force, this chain tensioner effectively prevents excessive chain slap on uneven surfaces. This significantly reduces chain slap noise against the frame and greatly decreases the risk of chain jumping off due to a loose chain – for a smoother and safer ride. **[Primarily Compatible Models:]** **Engine Size:** 47cc, 49cc, 110cc, and other small displacement engines. Vehicle types: Pocket bikes / Mini street motorcycles / Mini motocross motorcycles (e.g., CRF50/70 models) / Mini quads / Four-wheeled beach motorcycles / Some go-karts (Important note: Due to the variety of mini model frames, please check before purchasing whether your vehicle has mounting holes or brackets behind the engine or on the rear swingarm. It is recommended to compare the dimensions with the product size chart or contact the seller.)
