BMW K75: history and specs

The BMW K75 is a sport-touring motorcycle that was produced by the German company BMW from 1985 to 1995.

Background and Development

In the 1980s, BMW was looking to expand its motorcycle lineup beyond traditional boxer models. In this context, the K series was developed, featuring three- or four-cylinder in-line engines and a more modern, sporty design.

As for the K75's mechanics, the Bavarian brand didn't overcomplicate things and ultimately decided to follow the formula that had already worked successfully in the K100. However, this time, to reduce the final engine displacement, they didn't opt ​​to reduce the cylinder bore.

One of these was directly eliminated, although the longitudinal position within the frame was maintained, and the result was a noticeable reduction in vibrations compared to its larger sibling.

It was equipped with a 740cc three-cylinder engine with two valves per cylinder and a five-speed gearbox, the same one used in the K 100 but with the fifth gear ratio adapted to the new engine. The crankshaft was set at 120º and a balance shaft installed on it almost completely eliminated any vibration that might occur within the engine. Fuel delivery was via a Bosch LE-Jetronic injection system and it was water-cooled, with internal dimensions of 67 mm bore and 70 mm stroke. The compression ratio, as in the rest of the range, remained at 11:1 and the final power output was still 75 hp at 8,500 RPM. The final torque figure was 68 Nm at 6,750 RPM, and the top speed was around 210 km/h, achieving acceleration from 0 to 100 km/h from a standstill in 4.7 seconds.

Launch and Characteristics

The BMW K75 was presented to the public in 1985, along with its variants: the K75C (classic style), K75S (sport), and K75RT (touring).

It was designed as a high-performance sport and touring motorcycle, with features that made it ideal for both long journeys and sportier rides.

Technical Specifications

• Engine: The K75 featured a 740cc inline three-cylinder engine whose inline configuration provided a balance of power and smoothness.

• Performance: With around 75 horsepower, the K75 offered strong acceleration and agile handling, suitable for both open roads and winding curves.

• Suspension and Brakes: Equipped with adjustable suspension and disc brakes on both wheels, the K75 offered stable and safe handling.

• Style and Comfort: Its design was modern and aerodynamic, with a distinctive front fairing that provided wind protection. The RT version was equipped with side cases and a full fairing for long journeys.

Popularity

The BMW K75 was very well received by critics and the general public. It was praised for its smooth ride, excellent handling, and versatility for different riding styles.

During its production run, the K75 earned a reputation as a reliable and durable motorcycle, ideal for long journeys or daily city riding. It was also appreciated for its ease of maintenance and ergonomic comfort for both rider and passenger.

Although production ceased in 1995, the BMW K75 remains a popular motorcycle among classic motorcycle enthusiasts and collectors.
