After changing its brand name from Confederate Motors to Curtiss Motorcycle Company – taking the name of American aviator Glenn P. Curtiss who is credited with inventing the V-twin – the Alabama, US, company has unveiled what it says is the last internal combustion powered motorcycle it will ever build, the 2018 Curtiss Warhawk. Produced in a limited production run of only 35 units, Curtiss says pricing for the Warhawk begins from USD 105,000 (RM411,280).

Named after the World War II fighter flown by the famous Flying Tigers in China, the Warhawk carries an air- and oil-cooled 2,163 cc V-twin with two-valves per cylinder that produces 150 rear-wheel horsepower at 5,100 rpm and 217 Nm of torque at 2,000 rpm. Three camshafts actuate the overhead valves, with fuel fed into the engine by EFI, via twin 51 mm S&S throttle bodies.

Power gets to the ground via a Curtiss five-speed stacked gearbox with Andrews gears, driven by a primary belt drive and chain final drive. Weighing in at 258.5 kg with a modular frame machined out of 6061-T6 aluminium, the Warhawk has a claimed top speed of 265 km per hour.

Rolling on 18-inch BST carbon-fibre wheels with 160 and 180 width tyres, front and rear respectively, the Warhawk uses a double-wishbone parallelogram fork with Racetech monoshock in front, and cantilever Racetech monoshock at the back. Braking is by Beringer, with twin 230 mm Aeronal cast iron floating discs at the front wheel, and a single stainless steel 240 mm disc at the back.

Fuel for the Warhawk is carried in a see-through tank under the seat, which contains 16.25 litres. “We’ve spent the past 27 years working to optimise and perfect Glenn Curtiss’s V-Twin invention,” said Curtiss chief operating officer Matt Chambers, “everything we know is built into this machine.”

The 2018 Curtiss Warhawk will be the last motorcycle built by the company powered by internal combustion, as it moves to a future using electric motors. “The American V-twin is undoubtedly the most iconic and revered powertrain in motorcycle history,” said Chambers. “As we prepare to lead an all-new golden age of electrified motorcycles, this Curtiss Warhawk represents the best and final chapter in American V-Twin power and refinement.
