The chain RK 219 Kart Racing Chain with o-ring is a high-end product designed for karting enthusiasts. Made by RK Japan Co. LTD, a renowned motorcycle and karting chain company, this chain is synonymous with durability and performance.

Company History

RK Japan Co. LTD was founded in 1951 as Takasago Chain Co. LTD. Later, she formed the Takasago Manufacturing Co. LTD. Both companies merged in 1991 to become RK Excel Co. LTD. With its head office in Japan, RK Excel has an extensive global distribution network. Their main market is the motorcycle chain industry, both in the commercial and competitive sectors.

Features of the RK 219 Chain

The chain RK 219 Kart Racing Chain is available in several versions, including Blue RK 219 O-Ring, Green RK 219 and Gold RK 219. The O-ring version, like the Blue RK 219, is particularly popular for its superior performance.

  • Toric joint : The Blue RK 219 chain is equipped with an O-ring that keeps lubrication between the roller axis and the main pin. This prolongs the life of the chain by preventing overheating, kinking, severe drag and stretching.
  • Material and Finishing : The material used for RK chains is similar to that of DID, but the finish is not so perfect. However, this does not mean that the RK chain is lower. In fact, the RK 219 chain is considered superior due to its solid internal kernel.
  • Enhanced structure : The RK chain has thicker internal side plates, slightly larger diameter rolls and slightly larger and harder pins than the chain DID. These combined characteristics help strengthen the basic structure of the chain, thus avoiding stretching and overheating, which helps to maintain power.

Benefits of the RK 219 Chain

  • Sustainability The RK 219 chain is known for its superior durability, making it ideal for all karting classes.
  • Constantity : It offers constant performance throughout each session or output.
  • Permanent lubrication : The O-ring ensures permanent lubrication of critical internal support surfaces, thus extending the life of the chain.
  • Added Force : The outer size of the collar of the plate is larger than that of other chains, which provides added strength to the chain.

Applications

The RK 219 chain is ideal for karting classes like the Tag, KF2, KF1, where engines have a lot of low speed torque and power. Although the use of an O-ring chain may result in a slight loss of power of about 0.3 HP, the advantages in terms of durability and constant performance make it a preferred choice for karting drivers.

Conclusion

We clearly recommend RK 219 chains, both with and without O-ring, for all karting classes. Based on more than two decades of experience and testing, the RK 219 offers superior durability and constant performance, making it a superior choice for chains DID.
