2021 Road Hopper Type 9 Evo Technical Analysis & Specification Breakdown
Engineered by Road for the classic motorcycle segment, the 2021 Road Hopper Type 9 Evo pairs a 1337 cc (81.6 cu in) v2, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 88.9 x 107.9 mm (3.5 x 4.2 inches) with a 8.5:1 compression ratio.
