Featuring a robust 6,900 lbs tensile strength and advanced Nitrite Butadiene O-ring seals, it ensures smooth power delivery with minimal maintenance. Suitable for both street and off-road use, this chain includes a clip-type master link for easy installation, making it the reliable upgrade for riders seeking durability and efficiency. ## Description RK’s traditional round O-ring chain is a convenient blend of performance and affordability. SO’s 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. Review: A Superior Upgrade - This RK Racing Chain is an excellent product from a top-tier brand. Unlike the original equipment manufacturer (OEM) chain on my motorcycle, which stretched and required frequent adjustments, this chain has held up perfectly. The 520-SO series uses traditional O-rings to seal in lubricant, which keeps the chain running smoothly and significantly reduces maintenance. The result is a much safer and more effective chain with very little slack or wear, even after extensive use. I am absolutely pleased with this chain and its performance. It’s a durable, long-lasting product that makes a noticeable difference and provides peace of mind on the road. Review: Sport bike chain - High quality replacement chain for most sport bikes 400cc and lower. Great application for a 250cc or 300cc sport bike. Installed into 2020 Yamaha r3. ## Features - RK’s traditional round O-ring chain is a convenient blend of performance and affordability - SO’s 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007A8OOBQ | | Best Sellers Rank | #27,535 in Automotive ( See Top 100 in Automotive ) #27 in Powersports Drive Chains | | Brand | RK Racing Chain | | Customer Reviews | 4.6 4.6 out of 5 stars (1,449) | | Date First Available | February 15, 2012 | | Exterior | Steel | | Is Discontinued By Manufacturer | No | | Item Weight | 4.02 pounds | | Item model number | 520-SO-112 | | Manufacturer | RK Excel America | | Manufacturer Part Number | 520-SO-112 | | Model | 520SO | | Product Dimensions | 10.2 x 4.8 x 1 inches | ## Images ![520-SO-112 (520 Series) Steel 112 Link Traditional Street and Off-Road O-Ring Chain with Connecting Link - Image 1](https://m.media-amazon.com/images/I/613ynJqLF8L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Superior Upgrade *by P***. on August 21, 2025* This RK Racing Chain is an excellent product from a top-tier brand.
