Swing arm is calculated for stiffness so it's ok.
OK. It's just that  it looks much "thinner" (overall) and much less triangulated than anything else I've ever seen (on recent motorbikes).

Exhaust is also proper for this (not conventional) type of 2 stroke engine, as there is no back air load from (exhaust boost) exhaust pipes.
Yes, but I don't understand why you can do without that. Looking at the video (assuming I get the principles right) you should have the same efficiency boost (and associated emission reduction) from a properly tuned exhaust.
But to be honest I'm not sure I do understand exactly how it works: in particular, the road followed by the fresh air+fuel in the video below. Is the air injection chamber on top like a torus with ports on 3 "sides" of the cylinder (back, front and right) while the exhaust is the one on the left ?

I'm really no expert on all this, but one thing that strikes me is that I see a lot of sliding surfaces (with holes, lubrication is tricky), much more than on a conventional engine (2 or 4 strokes).

Interesting project anyway, good luck and keep us posted !!

MaX.

Those big exhausts for old 2 strokes has one purpose. Using the reflected pressure effect to put back the air-fuel-oil mixture into cylinder. As we are rinsing the cylinder with the fresh air and after that inject fuel there is no purpose in those type of exhaust. :)

For big road/track bikes however, 2 strokes seems to be dead for good.
He say's with a smile! LOL  :P ;D
Nah, despite the usual mocking, I don't really care if it's 2, 3 or 4 strokes: a good engine (for its purpose) is a good engine, no matter the technology behind. The outcome is what matters.

About that bike, the engine is by far the most interesting thing, would be nice to know more about it. The rest is ... well, design: love it or hate it. I hate the the fork head, not even a japanese on speed could have created that.

There a re a couple of design details that are a bit suspect to me (ground clearance, swing arm looks as flexible as a'50s bike, exhaust looks too small for a conventional 2 strokes), but it's almost always the case with prototypes imagined by architects. Plenty of time to sort things out later on.

Have to admit however, it's very unconventional so kudos for that.

PLease, learn to me how you did that. *fall on knees*

Btw, how the rims will handle that much power ? oO

He he ;) Nice to hear that. But I am not a creator of this 3D model. The profesional architect is. He is also the founder of the whole idea.

Rims with spokes are not a problem with power delivery due to propper force directions. In general, rims are not worse in any terms than solid rims except mass and complication level.

The thing with engine is, that uses the same way of oil delivery as 4 stroke. The air injection chamber was moved from below the cylinder to above it.

You can see more on jjsdesign.pl site ;)

I will post power curve of the 125 prototype engine. It does 15 kW. I think thats quite nice as for the first ever prototype of a compleatly new engine.

Btw. Not everything with 200 hp is fun to ride, nither 50 hp is always borring.

It's a polish bike, still under development. It has new type of cross, 2 stroke engine. 4 cylinders, 2 stroke , 110 HP, 500cc. What you can see is a render. And I have the 3D model from which that was rendered. So hopefully you can expect some nice looking mod. Just need time to learn how to make it to work.

I don't want to sound destructive, but... can you imagine how much torque you need to twist a rider and hold in that position? Maybe you don't know but that's over 50 Nm. NONE of the steering wheels on the market ( except bodnar's that is just a industry servo) is capable of something like that.
But any way. I wish you good luck :)

Plugins / Re: Live timing pluging needed for livestream
December 04, 2014, 09:10:24 PM
Live standing would be also nice, as you said. I remember that there is 1 parameter in log file that GP Bikes generates automaticly in "my documents/piboso" folder that tell us about position on the track ( meters passed of the track lenght  for example 1568 (meters of the 4600 m long track) .

With that information from all of the server clients we could do that.

Plugins / Live timing pluging needed for livestream
December 04, 2014, 05:17:11 PM
Hi!
As you might know, I will be streaming races of the STK 1000 championship, but I need some help to do so in proper way.
As things are happening fast in GP Bikes ( crashes, disconnects etc.) I need to be sure that what I'm commenting is truth. So here is my problem. I need a live timing plugin capable of showing small circles ( maybe with different colours ) with riders numbers on it around map of the track we are racing. Can anyone, familiar with plugins, tell me if that is possible?
