High-performance chain tensioner for 110cc/125cc/140cc off-road motorcycles with high-tension springs, aluminum alloy rollers, wear-resistant chain guide and no adjustment required.--DTEKGAZ

【Wear-Resistant Dual Roller Design】

Equipped with two high-quality rollers, typically made of wear-resistant nylon or an aluminum alloy with bearings, this chain guide offers optimal chain guidance and support. This reduces lateral vibration, minimizes uneven wear and the risk of chain derailment, making it particularly suitable for off-road use.

【Chain Protection and Extended Service Life】

Thanks to continuous and stable automatic tensioning, chain slap and wear from play are significantly reduced, extending the service life of the chain as well as the front and rear sprockets. It is a key component for improving drivetrain reliability and durability.

【Easy Installation and High Versatility】

The chain guide is compatible with most frame mounting holes and is typically mounted behind the engine or near the rocker arm bearing. Various mounting brackets or extended mounting holes are included to compensate for minor differences between vehicle models and simplify installation. [Wide Range of Applications] Especially suitable for situations where the chain tends to sag, such as off-road riding, long tours, and daily training. It offers riders safety and maintenance-free performance. Main Compatibility: Engine Displacement: Universal horizontal 110cc, 125cc, and 140cc engines.
