The Duke R is the sportier version of the 690 Duke, built around a larger 690 cc single that makes about 70 hp. It keeps the trellis frame and WP suspension but with firmer spring rates and an all-black fork, and it has uprated brakes including a radially mounted front caliper. The page presents it as a light, agile street bike that rewards a rider who works the engine above 2,000 rpm, with little wind protection.
