Shop parts for a 2015 Honda CRF230F Dirt Bike.
The 2015 Honda CRF230F continued as one of the more enduring and well-respected trail bikes in Honda's off-road catalog. The 223cc air-cooled OHC engine, steel frame, and Pro-Link rear suspension represented a design philosophy centered on long-term reliability and rider accessibility—values that the CRF230F consistently delivered on over its production run. These torque specs are the complete fastener reference for the 2015 model.
Thread Locker Guidelines for the CRF230F
Medium-strength (blue) threadlocker is appropriate for rear sprocket nuts, brake disc bolts, and subframe hardware on the 2015 CRF230F. These are fasteners that see vibration-driven loosening over trail use but still need to be removable for periodic service. Avoid threadlocker on the oil drain bolt, spark plug, or any coolant system hardware (the CRF230F is air-cooled, but the principle applies to drain and fill plugs everywhere).
