The 2011 Bonneville stays close to the previous year: an air-cooled, fuel-injected 865 cc twin dressed in a 1970s style with cast alloy wheels, short mudguards and megaphone exhausts. The low, narrow seat and low centre of gravity keep it friendly to new riders. An SE version with higher spec and two-tone paint was sold alongside it.
