The air-cooled three-cylinder engine is fitted upside down, the cylinder heads are facing the road; it uses a single overhead cam and two valves per cylinder. Displacement is said to range from 1850 to 2100cc, and power output will range between 160 and 250 horsepower. The bike’s dry weight ranges between 140-155 kg (309-342 lbs), but this depends on the materials used and options chosen.
The Nembo Super 32 is built on request and has so far been fitted on just two prototypes.
I hope we'll hear more from these guys!
Well I am confused about this one KZ If it is an upside down engine than wouldn't the cam be an under bottom head cam ??

Yes, that engine turns things upside down, it would be an under head cam, but I guess nobody would understand that term. It's an over head cam upside down.
If a pig lies on its back it's still an underbelly, or how would you call it? ;-)
Here some pics of a 125 Suzuki two-stroke; the white one above must be an earlier model, the engine didn't change that much:

Actually they may be the same year, the white one looks like seat and tank have been replaced. The rest seems to be identical.
I've never noticed that the K125 has the carb on the side, there must an air filter under the right side engine cover.
Kind of unusual place to put a carb, but it looks clean!

Yep Its a Suzuki K125, The white one is an earlier model, A K125 M1.

The black one is a K125 M2.

There is also a M3 & M4, the last model made.

I have restored a M2, I believe it to be a 1973 model.
The air filter is within the frame, between the battery box and the oil box and sucks air through to the carb.

I have restored a m2 to a pretty decent (I think) looking bike.

There are more pics in my 'Hello' thread but as im new to the site I think a mod needs to check over my first thread?

Cheers

Yeah the seat is from a Honda.
The 'carb on the side' is rotary disc valve induction where the fuel timing is metered by a gap in a rotating disc so that it is delivered straight to the crank at the precise time that it is needed and then closed when the combustion stroke takes place.I only ever knew of Kawasaki doing them.
Rotary Valve were good on the top end but not so good down low.My second ever bike a 1974 KX 90 had one and it warped fairly early on,just another moving part that detracts from 2 stroke simplicity.
Reed valve to crank and power valve is the way to go with modern 2 strokes.

Air is ducted from the back of the crankcases from the air cleaner behind where a carby would normally be.

Who can tell first which bike features this interesting looking bank of cylinders?

I have been looking for a bigger tank that would still look good on the Fury. I think this would do it.

That's right!
Interesting piece of work. TOHC - triple overhead cams!
I wonder when it will be available and who can afford to buy it....

It was on display at the Cologne motorcycle show late last year. 1200 cc supercharged VR6. There was an article about it in "Australian Road Rider" magazine last month, complete with exactly the same photo that you posted.

It's supposed to be in production late this year and will be sold in the "premium (expensive) segment" in Germany, Austria and Switzerland. But apparently they don't even have a factory to produce it in yet.

I owned once a Yamaha FS1 that I think had rotary valve system. Mine had a 70cc F5B cylinder and 16mm carb as far as I remember. Bit stupid I exchanged for a bicycle. Well just as stupid as I exchanged the Kreidler Florret TM for the Yamaha.

I will have to get back to you on that one. Off hand I would think it was one of those racing kind of Honda sports bikes

It's a Honda racing bike alright, but not any racing bike. Lots of people have been waiting for this bike and its technical specs.
There are rumors that Honda will mass-produce a street version of this bike...

Here an interesting shot of the parts under the fairing:

Yes, that's what it says in the background of the photo...
Interesting way to place intake and exhaust, not a first but still unusual. Also the cylinder tilting backwards 15 degrees, those boys at Honda seem to have given the bike some thought.
48 hp on the crank - a contrast to the CBR250R with less than half as much, but it should last longer.

How about this one:
175 horsepower
97 foot pounds of torque
aluminum frame with integral fuel
Öhlins suspension front and rear
6 speeds with wet slipper clutch
389 pounds without fuel

My guess - without googling it - it's the Suzuki Magura with a V4. Ugly as hell, not many sold.
