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 recently installed the RK Racing 520 SO chain on my bike, and I couldn't be happier. The 130 links fit perfectly, and the O-ring design really helps with durability. Plus, the steel construction feels super sturdy!

Broke after a few rides
I was excited to try the RK Racing chain, but unfortunately, it snapped after just a couple of rides. I followed all installation instructions carefully, but it just didn’t hold up as I had hoped. Definitely disappointing!

Great quality chain for the price
This RK Racing 520 series chain is a fantastic value! The O-ring feature keeps the dirt out and helps it last longer. I use it for both street rides and some light off-roading, and it performs great.

Installation was tricky for me
I bought the RK Racing chain and overall it seems good, but I struggled a bit with the installation. The connecting link was a bit tricky to get right. Once it was on, though, it works fine! Just make sure you have a buddy to help out.

Decent chain, but delivery was slow
The RK Racing chain itself is solid and works well for both street and off-road use. I like the traditional design, but I had to wait longer for it to arrive than expected. Not a huge deal, but I was eager to install it!
