RK Tagasako KRO drive chains

Range of O-ring sealed chains, ideal for karts.

The GB215KRO (Gold) model is approximately 20% lighter than the RK 219KRO series (subject to the closest gear ratio), with a 7.0mm pitch that makes the rotational roundness closer to the true circle, which improves power transmission efficiency with less friction.
It expands the option of having a more precise gear ratio, which is one of the secrets of today's champions.

The BB219KRO (Blue) made a sensational debut in 1988 as the "RK Blue".
BB219KRO has been the choice of champions in the highest categories such as the KF class and the OK class.
The latest technology is used in every component of these chains.

The MM219KRO (Green) – the world’s most famous kart chassis manufacturer has used the “Green” for its factory team since its debut in 2013.
Quality is self-explanatory from the results.

Finally the DD219KRO (Orange) uses the same components as the BB series.
The RK Orange series is preferred by "Orange karters" such as CRG, Exprit, Intrepid, etc.
