1970s Yamaha DT250 & DT250MX Valuation Report

Date: March 2026

Historical Overview

The Yamaha DT250 range represents one of the key trail bike families of the 1970s and early 1980s. Early twin-shock DT250 models offered a simple, rugged and very usable dual-purpose package, while the later DT250MX brought monoshock rear suspension, updated styling and a more modern riding feel. Both variants are now firmly established as collectible classic trail bikes in the UK.
