HFL reader and Art Center College of Design student Jeremy D'Ambrosio envisions GP racing evolving in a different direction than the current close-to-production direction or at least a class situated below Moto2 that could remain two-stroke. The leading arm front suspension on these concepts certainly differs from current racing practice and production norms, as do the tubular aluminum cradle frames. If all that's not weird enough, Jeremy has also included a 250cc, four-cylinder, vertically opposed engine. >
Recently I got a weird itch to re-create GP racing. why cant we still have 2-strokes? (obviously technology has improved greatly for them, making emissions a bit more reachable.) Why does MotoGP always have to be conventional? (conventional in means of prototype race bikes.)
With this project, i just wanted to branch out and make something that would be interesting to watch. (something new and exciting, as if racing wasn't exciting enough.)
Now, I'm not familiar with many GP rules or conventions, nor do i claim to be an engineer... so these bikes are purely concepts of preconceived ideas displaying what could be functional in an alternative way.
Each bike is equipped with a water/oil cooled, 6-speed, 250cc vertical-opposition 4 cylinder, fuel injected engine. sure, its unconventional, but it just sounds fun doesn't it? The final drive would be a conventional chain (unless someone would opt for a transmission similar to the Honda DN-01)
The rear suspension is a standard progressive stroke link-less set-up. While the front borrows from Bimota's wild leading arm system... although the linkage-bound steering mechanics have been replaced with ride-by-wire power steering.
The rear brake is a conventional disc; And the front resembles Mr. Erik Buell's perimeter braking system.
The chassis material could be up to MFG. but, displayed is a standard aluminum cradle frame (except for the Ducati, which gets their carbon fiber technology).
The styling is a mix between modern sport-bikes (mainly the geometry and stance), cafe racers (minimalistic mechanics and body works), and MX bikes (Paneled, vacuum formed body pieces).
