  • High Quality Material: The chain tensioner adjuster is made of high-quality aluminum material. Aluminum itself has good hardness and can withstand the pressure of chain operation. It is not easy to deform even after long-term use, ensuring stable tension on the chain. At the same time, it has good stability and can adapt to complex conditions inside the cabin, even if it is used for a long time, it can maintain good performance.
  • Scope of Application: The chain tensioner regulator measures 3.39 × 0.59 inches. This product is compatible with the Z50R, Z50A, CRF50F, CRF70F, CRF80F, CRF100F, XR50R, XR70R, XR75, XR80R, XR80, XR100, C70, CT70, XL75, XL100S, XL80S, and NS50F motocross models. Whether performing routine chain maintenance on these models or addressing chain tension issues after off-road riding, this tensioner adjuster is directly compatible for use.
  • Easy Installation: When adjusting, first confirm that the tensioner is securely fixed. Rotate the adjusting screw clockwise with a regulator to increase the pressure on the chain and increase the tension. Rotate counterclockwise to reduce pressure and loosen tension. Gently shake the chain while adjusting, observe the tightness until there is no obvious looseness or tension in the chain. Stop adjusting at this point, and the tension will be in the appropriate state.
  • Practical Function: The chain tensioner adjuster can accurately control the chain tension by adjusting the screw. When the chain shows a tendency to loosen, it can be tightened in a timely manner to avoid shaking, jamming, or even falling faults caused by the chain being too loose during driving. At the same time, it avoids abnormal transmission noise caused by excessive tightness, reduces the possibility of broken chain links, and extends the service life of the chain system.
  • Compact Design: The chain tensioner adjuster adopts a compact design, which will not occupy too much engine compartment space. Even if there are dense pipelines and components in the engine compartment, the position can be easily adjusted in limited space during installation,. Daily storage is also very convenient, as it does not take up extra capacity when placed in the toolbox. Whether placed in a car tool kit or backpack, it can be easily carried.
