does Harley have timing belt or chain ?

Example of the M8 engine

Harley-Davidson motorcycles generally use timing chains rather than timing belts. The timing chain is part of the engine’s internal components and connects the crankshaft to the camshaft, ensuring that the engine's valves open and close at the correct times during the combustion cycle.

The use of a timing chain is more common in Harley engines due to their design, durability, and the fact that chains require less maintenance compared to belts. Additionally, timing chains tend to last longer and handle the high power and torque of Harley’s V-twin engines better than belts would.

However, the chain may require occasional tension adjustment and, in some cases, replacement as part of regular maintenance.

In contrast, many modern vehicles and some motorcycles use timing belts, which are quieter but typically require more frequent replacement than chains.
