The Curtiss Motorcycle Company is the descendent of Confederate. It was created last year with the specific aim of building electric bikes. But its first machine – the Warhawk – is very much petrol-powered.
If the Warhawk looks familiar, it’s because it’s virtually identical to the Confederate FA-13 Combat Bomber. It matches the earlier Confederate in both style and spec. That means it uses the 2163cc S&S X-Wedge V-twin, making 150hp at the rear wheel and weighs 258.5kg. Acres of machined aluminium abound and there are the same intricately worked-out details that made Confederate’s bikes so distinctive.
However, this will be the only petrol-powered Curtiss in a range that’s otherwise set to be dominated by electric bikes. The firm is planning three electric models at the moment. All will use motors and electronics from Zero. But unlike Zero’s own bikes, some of the upcoming Curtiss models will feature two of the electric motors. That could add up to as much as 138bhp if Curtiss uses the most powerful Zero motors.
The electric bikes will be called Hercules, Zeus T Block and Starfire V Block. The names suggest that the Hercules will have a single motor while the Zeus and Starfire will have twin motors. One teaser image from Curtiss appears to show electric motors protruding from each side, rather like the cylinders of a BMW boxer. Could that be the Zeus T Block? And does it mean that the Starfire V Block will have its motors arranged like a V-twin?
Curtiss is expected to unveil at least one of its new electric bikes at the Quail Lodge Motorcycle Gathering on 5th May. In the meantime, the company is offering the Warhawk right now. It will make just 35 of the bikes, each at a price of $105,000 in America. If you’re intrigued as to what it’s like to ride one, read our test of the Combat Bomber here.
