What makes the BMW R27 (250cc) exceptionally special and highly sought after by collectors comes down to its unique engineering, historical significance, and legendary build quality:
Smooth-Riding “Thumper”: Single-cylinder motorcycles are naturally prone to heavy engine vibration. To solve this, BMW completely suspended the engine and transmission on heavy rubber mounts inside the frame.
Silky Smooth Cruise: This isolated the engine’s vibration from the handlebars, footpegs, and frame, giving the R27 a surprisingly smooth, refined ride compared to any other vintage 250cc single-cylinder of its era.
Final Single-Cylinder Shaft Drive: The R27 (produced from 1960 to 1966) was the last single-cylinder motorcycle BMW manufactured for nearly three decades (until the F650 in 1993).
The Ultimate Evolution: It represented the highest peak of development for BMW’s post-war shaft-driven 250cc series (following the R24, R25, and R26).
Earles Front Fork: Features the legendary Earles leading-link front fork setup. Designed specifically for sidecar work and heavy touring, it prevents front-end dive under heavy braking and gives the bike a plush, stable ride quality.
Fully Enclosed Shaft Drive: Unlike chain-driven competitors that required constant adjustment and cleaning, the R27’s fully enclosed shaft drive system is remarkably low-maintenance, clean, and durable.
18 Horsepower Engine: Thanks to a revised camshaft, higher compression ratio, and an upgraded 26mm Bing carburetor, the R27 produced 18 hp—a noticeable bump over its predecessor, the R26 (15 hp).
Capable Cruiser: It was capable of top speeds around 80 mph (130 km/h), making it a very usable, highway-capable vintage machine.
Mechanical Masterpiece: Because it was relatively expensive when new, fewer were produced compared to smaller lightweight bikes of the 1960s.
Resale Stability: Clean, matching-number R27s consistently command top dollar at classic auctions (such as Bring a Trailer, Mecum, and Bonhams) because of their reliability, museum-grade aesthetics, and rich German heritage.
