Good stuff! Never seen this bike before.. Who makes these?


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.


110hp from a 500cc 2 stroke??

That's bugger all!

Well bugger me backwards 110hp, as mattey rightly said thats nout more than the power of a rabbits fart!!! It should at least have the power of 2 rabbits farts or 1 and a half pig farts!!!

I am on the right forum aint I???? 

Very nice render though, looks like at least 2 pig farts fast to me!!!

Its not alot but I thought its about right?  ???

Naked too.. All naked bikes should be wheelie machines!!  ;D interesting bike! Wonder if it will have the low end torque being a 2stroke?


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.

I agree.. A local track I race at has all the classes racing through the weekend.. The guys that have the most fun are on the 125's.. Corner speed is insane!!! lol. Also the vintage 50cc class has a full grid.. Too funny watching them neck and neck tucked in down the straight.. Doing 5mph lol.

Anyway, maybe this will inspire a naked bike class in gpbikes? Ktm Superdukes etc. would be cool on the tight twisty tracks  ;)


Well im sorry for being so ignorent about 2 stokes :P all i though was a 500 street bike would be around the 150bhp mark...

And dont get me wrong, i love small capacity bikes! My 33bhp sv650 (restricted) was an absolute blast to ride and although its a reletivly big step up, my Daytona 675 is the biggest bike id want to ride on English roads.

Lol to be honest.. I dont know enough about engines  :D
Can 2strokes produce more power?

My 600 has around 105-110bhp maybe less than that now lol. My fireblade about 160bhp..

Didnt the old 500gp bikes have around 150bhp? I guess thats alot..

I still prefer big bikes to get the adrenaline pumpin!!  ;)

Road riding sucks... Unless going on a trip.


i think the "old" 2 stroke motogps have had something around 160bhp and the "problem" of these realtive big 2 strokes is the performance explosion.
you can watch a trailer of "the unrideables" on youtube.


Or maybe the EU environment regulations play a big part. Remember the latest Aprilia 125s were restricted due to to emissions.
I stopped gaming (and GP-Bikes)

thats a good point, i think i remember something from a 2 stroke 500cc engine that couldnt get licensed.

Stop wondering, it won't :)



Few years back there was a lot of people looking at 2 stroke cycle with fuel injection and mechanical valve operated exhaust ports to reduce emissions, wonder if its a development of those ideas
