250 cc · 16 hp
The Adler MB250 is a parallel-twin two-stroke tourer from West German manufacturer Adler, produced from 1953 to 1957. The 250 cc twin was among the most technically refined motorcycles in its class at the time. Adler, better known for typewriters and bicycles, fitted the MB250 with a leading-link front fork and swingarm rear suspension, significantly improving ride comfort over contemporary rivals.
The MB250 appeals to collectors of historic German motorcycles and veteran machinery. Its rarity and technically advanced design for the early 1950s make it desirable on the classic market. Riding characteristics are typical of period 250 cc two-strokes: lively, lightweight, and requiring active gear changes. Access to a reliable spare parts network is essential before purchase. It competes on the collectors' market with the NSU Max and DKW RT 250.
Check cylinder bore and piston rings for wear; two-stroke engines of the 1950s are typically due for a rebuild by 15,000–20,000 km and parts are scarce.
Inspect the carburettor for seal wear and confirm the float bowls are not leaking; original gaskets are nearly unobtainable.
Check the wiring harness for previous repairs or non-original replacements; decades-old loom insulation has become brittle.
Inspect the fork legs and seal rubbers for leakage; replacement fork seals need to be custom-made.
Verify completeness: original headlamp shell, instruments, and exhaust silencers are difficult to replace and significantly affect value.
