The RC8 R was delivered to the United States in 2010 as a 2011 model with more track-oriented features than the standard RC8. Engine displacement increased to with a higher compression ratio of 13.5:1. It has titanium intake valves and a low-friction diamond-like carbon (DLC) treatment on its camshafts' finger followers. The RC8 R's WP suspension includes a 43 mm inverted fork at the front end, with a titanium-aluminum-nitride low-stiction coating on its sliders. A high-end shock supports the bike's rear, and its piston rod is also finished with the titanium-aluminum-nitride coating. The fork has three modes of adjustment (compression damping, rebound damping and spring preload), while the shock separates the compression damping into high and low speed circuits and has ride-height adjustability. An adjustable steering damper completes the suspension.
