Decade-End CR250 Maintenance Summary
The 1989 CR250 represents the culmination of a decade of continuous development for Honda’s 250cc MX line. By this point, the CR250 had evolved from the raw, simple Elsinore machines into a sophisticated production race bike with HPP power valve, Pro-Link rear suspension, and well-developed chassis geometry. Maintaining this bike correctly means regular top-end service (every 10–15 hours), annual linkage pivot inspection and re-greasing, seasonal brake system inspection, and fastener verification at every interval. These practices keep the 1989 CR250 performing at the high standard Honda achieved by the end of the decade.
