Long-Term Preservation Tips
For the 2006 CR125, proactive preservation is important given its status as one of the final CR125 models. Keep the engine sealed with fresh top-end gaskets every 10–15 hours, replace axle and linkage bearings on schedule, and store the bike with the engine protected against humidity during the off-season. At every service, replace any fastener that is worn or shows thread damage rather than reusing it—the cost of fresh hardware is minimal compared to the effort of dealing with a seized or stripped fastener later.
