The frequency of rebuilding a CRF250R depends on factors such as riding style, maintenance, and usage. Generally, a top-end rebuild is recommended every 20 to 30 hours of riding, while a bottom-end rebuild may be needed every 50 to 100 hours. Regular maintenance and monitoring of performance can help determine the right timing for a rebuild. Always consult the owner's manual and consider your specific riding conditions for the best guidance.
