Maximum torque was delivered at 5,500 rpm and the engine redlined at 7,200 rpm. The alloy wheels were spoked and wore tubed tyres. The front brake had twin 230 mm disks and ATE callipers, the rear brake was a 200 mm SLS drum. The R90S and the other BMW “/6” series front brakes had an unusual system whereby a master cylinder on the top frame tube was activated by a cable from the front brake lever.

The machine was first delivered to Holland and was first registered there by Mr. Merbis with the registration number XR-38-34. The BMW has extensive documentation and invoices for maintenance dating back to 1996. It has always been lovingly maintained which reflects its current condition. A complete service was recently done.
