Caution
-
Every chain has life span.
We recommend that you check the chain elongation before each race/practice. (O-ring and Non Sealed chains)
Please do not use Gasoline, Kerosene for cleaning the chains. It may damage the O-ring (seal) and shorten the life span.
Special O-Ring sealed chain
It expands the option to have a more precise gear ratio, which is one of the secrets of today`s Champions.
O-Ring sealed chain
BB219KRO has been the Champions’ choice in the highest categories such as KF class and OK class.
The latest technology is used in every component in these chains.
MM219KRO
The quality is self-explanatory by the results.
DD219KRO
RK Orange series is preferred by “Orange karters” such as CRG, Exprit, Intrepid, etc.,
Q&A: Frequent question about O-ring (sealed) chain
Q: Do the O-ring (sealed) chains create more friction than Non sealed (Non O-ring) chains?
A: No, absolutely not.
Friction is dramatically reduced once the chain heats up (proved by every Dyno test and by the results).
KRO’s stronger components and self-lubricant construction help race performance and a longer life. (3-4 times longer than Non sealed (Non O-ring) chains per our test data.)
A: No, absolutely not.

Non sealed chain
Caution: Life span is shorter than KRO.
