BMW R100S 1973

BMW R100S 1973

When we first met with Giles he bought in his BMW R100S to show us it had undergone some work already so not a standard machine by any means, it had a café racer styled seat unit, sub frame with twin shocks, aftermarket exhaust cans, mikuni carbs and rear sets. We spoke about the ideas that Giles had for his bike and the brief was quite short he wanted it to be a bobber and a fork change to a Ducati monster set that he had bought and originally he wanted to run without mudguards.

So we set out on this build by designing and manufacturing a set of yokes to hold the Ducati M600 forks and re spacing the wheel for a new Brembo caliper and disc with this done we next concentrated on the rear by removing the seat unit and sub frame, manufacturing a boss to go inside the frame rail we added a small saddle style seat and a new shock set up.

Hiding the battery where the air box once sat was the next move so we could start at wiring using an M-unit blue and small push button switches on the handle bars, indicator and rear light mounts where then manufactured to keep all the lines in close and the rear light sits nicely under the seat with wiring hidden in the frame rails.

The rear brake also needed some attention as the old unit would barley stop this bike so we used a Kawasaki ZX6 master cylinder to a new Brembo mini caliper and a machined caliper hanger and brake stay, the time came to look at painting and for the customer to choose a colour this did not take long as he has an old landrover that is of the same olive green. But just before we sent this up to Pro Kustom it was decided to add mudguards both front and back and this was the right call as it now has a distinguished look.
