End-of-Decade Maintenance Notes
For a 1999 CR125 that has been in regular use, a thorough seasonal inspection is worthwhile. Inspect the frame for fatigue cracks, particularly around the swingarm pivot tabs and the engine mounting points. Inspect the subframe attachment bolts for thread wear. Check the front caliper slider pins for free movement—seized caliper sliders cause uneven pad wear and degraded braking performance. Address any issues found before the next riding season to keep the bike in its best condition.
