Originally built just for 1961 and shown in that year's sales brochure, not a lot is known about this model apart from it was intended as an off-road/enduro machine. It was available with optional QD lights, used the Trials type Vokes 'D'-shape air filter, wide-ratio gears, high level exhaust, Energy Transfer Ignition, crankcase undershield, side stand only and small triangular toolbox.
