Kart Chain

  • 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
GB215KRO (Gold) is approx 20% lighter than RK 219KRO series (subject to the nearest gear ratio), with a 7.0mm pitch making Roundness of Rotation closer to the true circle, which improves the power transmission efficiency with less friction.
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 (Blue) made a sensational debut in 1988 as “RK Blue”.
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 (Green) – world’s most popular Kart chassis manufacturer has been using the “Green” for their factory team since its debut in 2013.
The quality is self-explanatory by the results.

DD219KRO (Orange) uses the same components as the BB series.
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.)
Non sealed chain
GB219KR (Gold/Black) – Non Sealed (Non O-Ring) chain series, distributed worldwide since late 1990’s for the lower horsepower karts at economical price.
Caution: Life span is shorter than KRO.
