The 250GP racer of the future?

Galleries -


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).

    Well done Mr. D’Ambrosio! I love the concept. That disc on the front of a 250 would be insanity though :)

    That is a very refreshing take on a bike! I absolutley love and would buy one too. I think, from their appearance, they could be build cheaply. And they appear to have ‘room to grow’ for bigger motors if needed. That would be an interesting concept for a rolling chassis kit.

    Thank you for the chance to show my work to enthusiasts! -One small typo. I am not currently an Art Center Student; I am transferring over to Art Center from my previous design school between these upcoming months.

    -To Isaac. Yes the construction was thought to be cheap to produce. Most of the components such as the body pieces and smaller mechanical bits are “quick-change” (and quick to manufacture), and can be broken down and replaced easily in pit conditions.

    The chassis would allow growth to different engine configurations. As it stands, the chassis design for this bike was used as a 4-stroke street-legal minimalist bike in another project past.

    Very sweet designs. Now, if you want to know why MotoGP is so mired in conservatism, start perusing and you’ll pick up a lot of the answers there.

    The bottom line is cost. MotoGP racing is getting way too expensive (like F1) so the powers who are running it are throwing in all sorts of artificial restrictions to (supposedly) try and keep costs down. Hint: It ain’t working.

    I don’t know about it’s GPability but that looks like fun and sharp nonetheless. Style wise I’m all over that. I applaud anyone who takes the concept of cafe racer past the 1960′s and re-imagines it as a modern machine apart from nostalgic lifestyle cues.

    Check out the Oct issue of Bike magazine from the UK (I think, green street triple on the cover). There’s a great article on an engineer with an improved hub center front end that should keep your imagination humming. He has some interesting solutions that solve some of the clearance and feel issues of the hub center concept.

    Looks damn GOOD!!! It would make for one sweet ass ride on Palomar.

    very cool, good work jeremy..
    nice renders. do they turn?
    i would love to see the honda, in HRC colors not repsol’s..
    but that just me liking the renders..

      “Do they turn?”

      Probably hub centre steering

  • Jeremy D'Ambrosio

    Yes, these bikes use hub center steering; And the leading arm structure is designed to allow the wheel ample movement in the left and right direction (i made sure there was no clearance issues)

  • Nick

    I think he meant the renders, do the renders turn?

  • Collin

    Nice work, as usual. AIP misses the nut
