RKs traditional round O-ring chain is a convenient blend of performance and affordability. SOs O-ring is constructed from Nitrite Butadiene to seal in lubrication and deliver smooth power with minimal seal ring drag or loss of horsepower. 520SO chains are suitable for low to mid-range CC motorcycles that came from the factory with sealed chains. 520SO can be used for both on street and off-road up to 400ccs. Tensile Strength: 6,900 lbs; Max CC Rating: 400cc Street, 400cc Off-road/ATV; Max Horsepower: 60 HP; Weight per 100 Links: 3.39 lbs; Max Chain Width: 21.7mm; Master Link Included: Clip type.
I installed this RK Racing 520 O-ring chain on my dirt bike and it works like a charm! The 66 links fit perfectly and the steel construction feels super durable. Have used it on a couple of trails and the performance is just what I needed for both street riding and off-road adventures.

Excellent Quality, Easy to Install
I recently upgraded my bike's chain to this RK Racing unit and couldn't be happier. The install was a breeze thanks to the connecting link. The O-ring design really helps keep the chain lubricated and smooth, highly recommend it for anyone looking for reliability.

Solid Chain, But Delivery Took Forever
The RK Racing chain is solid and holds up well under tough conditions. Just wish the shipping had been faster, took about two weeks to arrive. Once I got it installed, I was really happy with how it performed on my motorcycle.

Nice Chain, Color Not as Expecte
Got this chain for my bike after hearing good things. It’s a good length and durable, but I was hoping for a more polished look. The steel is fine, but it looks a bit dull compared to what I imagined. Still does its job, though!

Disappointing Quality Control
Unfortunately, my RK Racing chain arrived with a serious kink in it. It didn’t work right even after trying to adjust it. I expected more from a brand like this. Had to return it and find a different option, which was a hassle.
