The 70 teeth clutch crown DD2 2021 is an essential transmission piece for engines Rotax Dd2 used in karting. Designed to meet the requirements of the competition, it provides the connection between the box output and the rear wheel shaft, ensuring reliable power transmission, efficient and adapted to the characteristics of the DD2 motorcropper group.
This clutch crown is specifically developed for engines Rotax DD2 vintage 2021with 70 teeth Adapted to the standard transmission of this motorization. It mises directly on the DD2 clutch system and is an essential element for ensuring a good transmission ratio between the engine and the wheels.
Made in a robust material, it is sized to withstand the high torque generated by the engine Rotax DD2, while ensuring high longevity and constant performance, whether training or competing.
The clutch crown plays a central role in the Kart power transmission :
It is positioned on the transmission case DD2 engine.
When a driver opens the accelerator, the engine clutch is progressively committed.
The crown then receives the rotational movement transmitted by the clutch.
This rotation is then transmitted to the chain that connects the crown to rear sprocket, causing the wheel.
The Crown size (number of teeth) determines the transmission report With the pinion, influencing directly:
the acceleration of the kart,
the advanced speed,
The engine response in some diet ranges.
Within the framework of Rotax Dd2The clutch system is integrated and does not require a string between the motor and an external box: the crown engages directly with the rear transmission. This allows better mechanical efficiency and a more direct engine response.

When changing the crown, systematically check the status of the rear sprocket as well as the chain to ensure homogeneous wear and optimal transmission.
It is recommended to regularly check the string of the chain and wear of the ring for the crown to ensure constant safety and performance.
If you are not familiar with the assembly or transmission settings, entrust this job to a karting professional to ensure proper and safe assembly.
TheFull-strings OTKis designed to perfectly wrap the transmission of your kart (pinion, chain, crown). Mandatory in most competitions, it provides maximum protection against projections of grease and debris. In the event of a high-speed chain failure, it plays an essential shield role to protect the driver and chassis.
