sprint scooter :)

130 km/h in about 6.8 seconds. Faster than most cars.
the whole thing weighs 38.5 kgs.

I did advise in construction. The owner/rider hadn’t touched composites before. He started with some flat panels before making small parts. For the big rear part I had to help him a bit though.
I did the lay-up, and some laminating(the visible layer :slight_smile: ), and the bagging and post cure. The rear part weighs 1100 grams, and has some SAN foam in it, as well as uni an biax layers.

How many pieces?

nice stuff! :smiley:

The back consists of 2 halves, front is one piece, and the inside piece(footboard) is being made out of one piece. When it get’s a bit warmer we’ll be making a new backpiece. Below 1 kg is the goal :smiley:

Cooool:D :smiley: :smiley:

Thats a damn cool scooter! :smiley:

Any spec on engine and what not?

I’m not really into the engine stuff(although it’s part of my education, and composites are not, haha)

But this is what I know:
AC EVO 70 CC, aircooled(lighter) 19.8 HP. Gets started by a external (drillmachine)motor.
It has several sensors in it wich the rider can see on a display. Ideal start temp is around 70 degrees celcius, and gets up very fast during the run. After the run it’s cooled by spraying some water over it.
It has a carbon carterpan wich saves around one kg. So there is already 4 kg saved by using carbon, 1 kg by using aircooling, 1,5 by making the wheels lighter, and the rest is chopped off the frame, and using lighter stuff.

here’s a small movie I made,its the outside one (it’s not the one in the startpost, but build this one’s seat also :slight_smile: )

hehehehe this is the cooolest bike I ever see :smiley:

Good work looks really cool.:smiley:

Very cool video. If you can share, I would like to see the process of how you did the layup and mold if you did one. Interested in how you made hardpoints for engine and suspension mounting…

engine and suspension are all on the original but lightened steel frame. we don’t have pictures of doing the layup (50 minutes open time, not enough time to do anything haha) And I’ll try to find a picture of the mold (it’s the worst mold I’ve ever seen though, thank god for PVA and clearcoat :stuck_out_tongue: )

Oh, for some reason I thought it was a monocoque, without any steel structure. Do the rules state you need to run body panels? I would just strip the thing naked, unless there is a significant amount of wind resistance towards the end… but thats just me. Carbon Fiber is pretty though : )

Thanks for sharing!

yes, 70 percent of body panels need to be original shape and attached. It’s 2,5 kg’s heavier than the aluminum frame racers. :wink:

Cooooooooooollll
