The 219 chain is the most commonly used drive chain in professional karting. It is considered the standard for direct-drive engines such as OK models, as well as for engines with a centrifugal clutch, for example:
Thanks to its optimal combination of strength, low rolling resistance and high durability, the 219 chain is the first choice in karting for high-performance 2-stroke engines.
The 219 chain (type 219) features the following dimensions:
These specifications ensure precise power transmission and smooth operation – crucial for consistent lap times in racing conditions.
Depending on the manufacturer, the 219 chain is available in different quality levels. The most common versions include:
O-ring chains or reinforced versions such as the DID SDH model offer:
There are also noticeable differences in friction and smoothness between models. The right 219 chain depends on the intended application, track conditions and personal driving preference.
In karting, the 219 chain is used exclusively as a so-called endless chain, meaning it does not use a master link.
The advantages:
Especially under racing conditions, where extreme loads occur, this design is essential.
The 219 chain is the standard in karting for good reason. It offers the ideal balance of performance, durability and safety. Whether running an OK engine, IAME X30 or Rotax Max – a high-quality 219 kart chain ensures reliable and efficient power transmission.
