Engine Break-In

The engine break-in period for your motorcycle is the first 500 miles (800 km) of operation. During this break-in period, critical engine parts require special wear-in procedures so they seat and mate properly. Read, understand and follow all break-in procedures to ensure the long-term performance and durability of your engine.
NOTICE
Failure to properly follow the engine break-in procedures outlined in this manual can result in serious damage to the engine. Avoid full throttle operation and other conditions that may place an excessive load on the engine during the break-in period.
The more cautiously you treat your motorcycle during the break-in period, the more satisfied you will be with its performance later on. Overloading the engine at low RPM and/or running the engine prematurely at high RPM may result in damage to the pistons and/or other engine components.
Observe the following precautions during the break-in period:
  • Upon initial start-up, do not allow the engine to idle for long periods as overheating can occur.
  • Avoid fast starts with wide open throttle. Drive slowly until the engine warms up.
  • Avoid running the engine at extremely low RPM in higher gears (lugging the engine).
  • Drive within the recommended operating speeds and gears.
