Product Info

The ProX 520 MX Chain is a non-seal 520 race chain made for ProX by a Japanese OEM factory and built to pair with ProX sprockets. Solid, shot-peened rollers, quad-staked pins and heat-treated plates give it strength and wear resistance, while lightening holes in the inner plates save about 3% in weight. This gold version comes in 120 links with a clip-type master link.

Your chain carries every bit of motor torque to the rear wheel, and a stretched, kinked or rusty chain wastes power, slaps the swingarm and wears out your sprockets. A non-seal MX chain has no O-rings between the plates, so it turns with less internal friction than a sealed chain, which is why it is the race choice where efficiency matters most.

ProX gives the pins a hardened outer layer over a softer core to add strength and reduce wear, then heavy press-fits and quad-stakes them. The bushings and rollers are solid, the rollers are shot-peened, and the bushings, rollers and plates are heat-treated for high tensile strength, low friction and wear resistance. Every chain is pre-stressed and pre-stretched to reduce initial stretch, so it holds its adjustment after install.

Non-seal chains reward regular cleaning and lube. Cut the chain to length for your gearing, and if your sprockets are hooked or worn, replace them at the same time: a new chain on worn sprockets wears out fast.
