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.
This RK Racing chain was really straightforward to install, thanks to the included connecting link. I use it for both street and off-road and it held up well. Just a bit noisy at times, but I’m quite happy with its performance so far!

Great Upgrade for Off-Roading
Just swapped out my old chain for this RK 520 O-Ring and wow, what a difference! The link count is perfect for my dirt bike, and it provides a much smoother ride on rough trails. Totally worth it for the upgrade.

Not What I Expected
I was disappointed with this RK Racing chain. It arrived with a few scratches and took longer than promised to ship. Performance-wise, it's ok for street use, but I expected more durability for off-road. Wish it had come in better condition!

Okay for the Price
The RK 520 chain does the job, but I think I expected a bit more from the steel quality. It works fine for casual rides, but after a few weeks, I noticed some stiffness. Could be better, but it’s decent value for the money.

Solid Chain for My Bike
I recently installed the RK Racing 520 O-Ring chain on my street bike, and it feels incredibly durable. The steel construction is top-notch, and the 74 links fit perfectly. It rolls smoothly, even on rough roads. Definitely a solid choice for anyone looking for a reliable chain!
