BMW introduced the K100 in 1983 as a radical departure from its traditional air-cooled boxer twins. The new bike featured a liquid-cooled inline-four engine laid on its side, earning it the nickname 'Flying Brick'. It was a direct effort to compete with the multi-cylinder motorcycles from Japan. In 1985, BMW followed up with the K75, a 750cc triple that was smoother and lighter, which many riders came to prefer.
These K-series bikes are prized for their unique engineering and incredible durability, with many examples easily surpassing 100,000 miles. They represent a major turning point for BMW and offer a comfortable, capable, and distinctive riding experience. Their relatively simple mechanicals make them approachable for home mechanics, and they have become a popular platform for cafe racer and scrambler custom builds.
The market for K75 and K100 models is very accessible, with an average sale price under $8,000. The wide price spread reflects the vast difference between well-used examples and pristine, low-mileage bikes or professional custom builds. With a steady volume of sales, it's a stable market for anyone looking to acquire a reliable and interesting classic BMW motorcycle.
Buying Tips
- Check service records for regular final drive and transmission input spline lubrication. Neglect leads to costly repairs.
- Test the early ABS system if equipped. The warning lights should cycle correctly on startup, as non-functional units are common.
- Inspect the wiring harness and connectors for corrosion or brittleness, especially around the instrument cluster and under the tank.
- Listen for the fuel pump to prime when the ignition is turned on. Fuel systems can be problematic on bikes that have sat for long periods.
- Look for smoke on startup, which can indicate worn valve stem seals, a common issue as these bikes age.
Prices for K-series models range from a few thousand dollars for riders to over $31,000 for exceptional examples.
