Bahn Burner: 1990 BMW K1

Based on the K100, the 1990 BMW K1 was a sporting machine without a hint of touring pretensions.

At the end of the 1980s, the high-horsepower superbike category belonged to the Japanese motorcycle makers. But Germany’s BMW was about to unleash — in the words of Monty Python — something completely different.

Based on BMW’s 4-cylinder K100, a touring-oriented model first introduced in 1984, the new for 1989 K1 was a sporting performance machine without a hint of touring pretensions. According to motorcycle historian Ian Falloon in The Complete Book of BMW Motorcycles, in the late 1980s BMW took a look at the available Japanese superbikes with their firecracker performance and taut handling. Tops in horsepower and agility, all of these Japanese rockets featured chain final drive.

“BMW decided the time was ripe for a shaft drive Superbike,” Falloon writes, “one considerably more performance focused than the K100. When it was first displayed at the Cologne Show at the end of 1988, the K1 shattered the perception of BMW producing only conservatively styled touring and sport touring motorcycles.” Of the resulting K1 fitting into the established superbike category, a March 1990 Cycle report said BMW had gone its own way, just as BMW always had.

I have a '92 K100RS, 16 valve. Pretty much the same bike with different body work. Fast and smooth, but not what you want on a twisty back road. It's solid fun in fast sweepers though. I know what the author means about dropping the bike. I've dropped mine a couple of times, once when taking it off the center stand. No use even trying to pick it up without help. It really is a tall bike, I'm 5' 10" and it's all I can do to swing my leg over it, especially with a sleeping bag strapped on the pillion. As Richard said, the engine puts out quite a bit of heat inside the fairing, not nice in the heat of Summer.

I've just acquired a 'ketchup/mustard" K1 and wondering where to find replacement decals; my "K1" decal has two small scuffs. seems perhaps easier to paint small places by hand? thanks, z

I remember that ad well, Tony, and I had the same impression. I rode the one we featured, and the experience didn't blunt the desire one bit. Quite the opposite. There's just something very, very special about them. Just don't ride one in the summer! Richard
