The BMW R26 and R27 were the final evolution of BMW's post-war single-cylinder motorcycle line. Introduced in 1956, the R26 featured a new frame with an Earles front fork, a significant upgrade over its R25 predecessor. The R27, produced from 1960 to 1966, went a step further by mounting its 247cc engine and transmission in rubber bushings, a feature that dramatically smoothed out vibrations and set it apart from its contemporaries.
Collectors appreciate these singles for their classic design, durability, and relative simplicity compared to the more complex boxer twins. They represent the end of a long line of BMW "thumpers" that started in the 1920s. The R27 is often more desired by those who intend to ride their classics, as the rubber-mounted engine makes for a much more pleasant experience on the road. Both models offer a direct and engaging connection to a bygone era of motorcycling.
The market for the R26 and R27 is well-established, with a wide value range reflecting condition and originality. With 37 sales tracked, the average price sits around $12,600. Pristine, numbers-matching examples command top dollar, while running projects offer a more affordable entry point into vintage BMW ownership. Parts availability is quite good, which helps sustain the market for both restorations and regular maintenance.
Buying Tips
- Verify the engine and frame numbers match the headstock plate. Mismatched numbers are common but will reduce the bike's value.
- On the R27, inspect the rubber engine mounts for perishing or cracking. Worn mounts defeat the purpose of the vibration-damped design and must be replaced.
- Check for cracks in the frame, especially around the steering head and rear suspension mounting points. These bikes were often used as daily transportation.
- Listen for excessive mechanical noise from the top end. Worn rockers or pushrods are common issues that can lead to a costly rebuild.
- Examine the final drive for oil leaks and check for play in the bearings by wiggling the rear wheel side-to-side.
Prices range from about $4,500 for project bikes to $29,000 for pristine, restored examples.
