Despite costing 21 percent more than Suzuki’s swaggering 1,462cc C90 B.O.S.S., the sinister M109R B.O.S.S. delivers appropriately more engine capacity, performance, and bragging rights. While generally similar in style to the C90 B.O.S.S., the M109R breaks out with a big 1,783cc V-twin engine (22-percent larger), dual front disc brakes, and a much wider and lower-profile 240/40R-18 rear tire. Despite these upgrades, though, at 764 pounds, the M109R weighs less than 1 percent more than the 758-pound C90 B.O.S.S. Yeah!
