The Roctane, fifth member of the R 18 family, is a darker, more aggressive custom bagger. It drops the B's batwing fairing for a black headlight nacelle with a round R 5-style speedometer, and rolls on a tall 21-inch front wheel and 18-inch rear in place of the usual 19/16 combination. A high black handlebar, footboards with a heel-toe shifter, 27-litre side cases and a matt-black engine finish complete the look.
