High-strength, gold-plated drive chain, 25H-138 links, suitable for off-road motorcycles/mini motorcycles with small displacement, chain with oil seal via O-ring.--DTEKGAZ

【Compatible with Small Off-Road Motorcycles】**Specifically designed for small off-road motorcycles, minibikes, and some children's off-road motorcycles with an engine displacement of 50–125 cc. Specifications: 25 holes (equivalent to the international standard of 428 holes), total length 138 links. Precisely calculated to meet the replacement or modification needs of most common small off-road models.

【Lubricated Chain with Gold O-Rings】**This high-quality gold-plated chain is not only visually appealing but also provides corrosion protection. Special rubber O-rings between the links effectively retain lubricating oil, prevent the ingress of dust and mud, and significantly reduce wear. This extends the lifespan of the chain as well as the front and rear sprockets.

It is particularly well-suited for riding on dusty, wet, and unpaved roads. The track links are made of high-quality alloy steel and are heat-treated, giving them excellent tensile strength and wear resistance. Despite their lightweight construction, they reliably transmit power to small-displacement off-road vehicles and withstand the stresses of off-road use.
