DID chains have been among the most successful products in racing for years.
The versatility of the group and more than 80 years of experience make the products from Japan so successful.
In karting, the DID brand is omnipresent and one of the best-known drive chains for both the 219 type and the 428 type.
The SDH model series has a "special pin" which increases the service life of the chain by 140% compared to the previous model DHA. An excellent transmission efficiency
also reduces the frictional resistance when rotating around the sprocket, which means less effort for the motor and higher power output.
DID's SDH technology is currently the highest performing O-ring free product in the 219 series.
