Guideline
Weight, chain wear measurement 15 kg (33 lb.)

different chain positions.
Maximum distance at the longest
chain section

» If the distance is greater than the specified measurement:
– Change the rear sprocket / engine sprocket, chain and chain sliding guard.

chain changed in an authorized KTM-RC8 workshop, where they
have the necessary special tools.

Info
The engine power is transmitted by the rear sprocket to the rear wheel through 5 shock absorbers. They are subject to wear
during operation. If the shock absorbers are not changed in time, the rear sprocket carrier and the rear hub are damaged.
