Why We Picked It:
BMW just seems to have problems with anything that has a letter followed by a 1. The C1 was a disaster. In the automotive side, the M1 never really took off, but when the recent 1M was on sale, it was one of the best cars you could buy. Thus, between the M1 car and the C1 "scooter," there fell the K1 touring bike.
As we've harped on about during this list a few times, the biggest thing a bike needs to be efficient, especially for touring, is aerodynamics. If the bike is smooth, stylish, cuts the air like a knife but also looks good while doing it, it's often a win. Unfortunately, in the late 1980s, sometimes aerodynamics took a back seat to "futuristic" designs.
Thus, the "cyberpunk" influenced K1 was a blocky, squared off motorcycle that had to look in a dictionary to find out what "aerodynamics" meant. Perhaps the most damning review of it was while it had a superb 987cc longitudinal inline four that produced 100 HP and 74 lbs-ft of torque, it was labelled as "quick but not fast."
It bullied the air aside around its front fairings instead of cutting through it. It also weight 516 lbs dry, without having any fluids aboard. Fully wet, it ended up weighting over 570 lbs because of its large fuel tank (5.8 US Gallons), big radiator, and oil-hungry engine.
The only redeeming factor that the K1 has going for it is that it laid the groundwork for the K-series sport tourers, which eventually let to the K 1300GT in the early 2000s. In a way, it was the origin of the superb K 1600 series of tourers, but its descendants at least went to science class and learned about physics!
