The mature twin-shock R 100RS, by now with electronic ignition, Brembo front calipers and Nikasil cylinders. Period tests praised its wind protection, ride comfort and long range, while noting a low handlebar, soft suspension under hard riding and a high price. It remained a long-distance sports tourer rather than an outright sport bike.
