Break-in Guidelines
Help assure your CRF's future reliability and
performance by paying extra attention to how you
ride during the first operating day or 15 miles
(25 km).
During this period, avoid full-throttle starts and
rapid acceleration.
This same procedure should be followed each time
when:
• piston is replaced
• piston rings are replaced
• cylinder is replaced
• crankshaft or crank bearings are replaced
