BMW K100 Cafe Racer

While working on the R80 engine, almost finishing this project, I started looking for another one, a new challenge. After lot of thinking, Hondas, Yamahas, carb engines or injection I found out a motorbike that inspired me.


First of all it is BMW, pieze of engineering, it is a new challenge, lot more electronics in this bike plus the “brick” engine is another example of a indestructable pieze of German engineering.

Another challenge for me is work out the frame. As you can see, the rear end is quite ugly, with a pipe going down and creating an space under the seat. So I will have to cut and weld some pipes to make that part of the bike look more horizontal. In the same horitontal line, the tank should be cut as well so the whole bike looks more balanced.

Looking for an affordable K100 here in the States I found this one in Maine for $1300. Lot of ugly plastic so I could not wait to start taking the bike apart.

The exhaust silencer in this bike is way to long. For this reason I decided to cut it so that ends in the shaft of the rear wheel, much nicer.

Here you can see what do I mean with reworking the frame and tank to get a nicer cafe racer look. The bike will have this horizontal side look instead of the current random shapes. I mean random for a cafe racer because with all plastic one it had sense but not on a minimalist concept bike.

Let´s have some fun with the grinder… Now it is time to cut, bend and weld pipe.  After that time for gas tank.
