We bet you haven’t clapped eyes on a Cub like this one, though. It comes from the warped imagination of Matthew Roberts, the new Director of Motorcycle Operations at Deus Japan.
The Super Cub’s step-through construction is gone, replaced by long, elegant lines running uninterrupted from headlight to tail.
The epoxy composite monocoque body saves precious kilograms. Measuring just 105mm (4½ inches) at its widest point, it hides the fuel cell, battery, coil and electrics. All are laid out with surgical precision along a slender backbone.
Deus’ traditional attention to detail is everywhere. Handmade accoutrements pepper the Firefly’s form—such as the alloy top bridge, stoplight and rearsets. The suspension gets an upgrade with an external front fork rebound unit and fully adjustable alloy race shocks.
Every nut, bolt, bearing and bush has been re-engineered or redesigned, using decades-old factory blueprints as a reference. There’s enough milling and lathing in this little machine to leave the HRC factory team green with envy.
So all the lighting is attached with quick release mechanisms, so the Cub can race at the Fuji Speedway on Sunday and hit the Tokyo streets on Monday.
So Deus called in the local engine gurus at Ted’s Special, a company more used to working on the exotica in Honda’s own race collection hall. They over-sized and tuned the petite donk, staying just within the permitted 20% capacity increase.
“Since Japan is the birth place of the Super Cub, you have to deliver a design that punches well above its weight,” says Roberts.
