70hp single-cylinder engine

By Motorcycle.Com Staff, Nov. 10, 2009
KTM unveiled a new R version of the Duke 690 naked motorcycle at the 2009 EICMA show in Milan, Italy.

Unlike the Duke 690 which is actually powered by a 654cc engine, the Duke 690R has a full 690cc. With an extra 1.77 inches of stroke, the Duke 690R has a claimed output of 70hp which, according to KTM, makes it the worlds most powerful single-cylinder engine.

As per KTMs usual custom, the R version of the Duke has an orange trellis frame. The 690R keeps the 690s WP suspension, with the rear spring also orange. Other changes include a blacked out fork and carbon fiber mudguard.

KTM claims the Duke 690R's engine is the world's most powerful single-cylinder power plant.
