1930 Peugeot board racer with a 9cyl radial engine .. No capacity given but looking at the size of the pots not very much .. 

Couple of Demm 75cc DOHC racers .. Neat little engine ..

Apparently the engine is a modern scale replica of a French WW1 Era Gnome and Rhone aircraft engine and was put together by Bo Hare.  100 cc.

Awesome bike the Aprilia .. Back in the day there used to be a dealership in Croydon that used to have them displayed outside on the pavement .. 
One in classic Aprilia paint scheme just needs a bit more green in it .. 
 

That’s where I bought my Guzzi v11 Le Mans, titanium exhaust&remapped ECU from.
Nice people!

Which might make it a rotary engine and not a radial. If rotary? Hmmm a bit dodgy for a bike? Still, with all those exposed chains maybe that is the least of the rider's worries.

More Max Hazan ludicrous and genius fabrication and machining skills, this time a 500cc BSA B33;

It is a radial engine 

not rotary.

Wankel would be rotary.

Weren’t some radial engines, in the early aviation days, rotary engines too?

/ Wikipedia

The major difference between the radial engine and the rotary engine is that radial engines have pistons that move in a reciprocating fashion that cause the crankshaft to rotate. ... A rotary engine does not have pistons but rather a triangular rotor that rotates around an output shaft.

I have a different kind of rotary engine in mind, the one you are referring to is the Wankel-engine. There were radial piston engines that rotated as well, see this example

Couple of exotic 60's Mondials an' a super dinky Ceccato 75cc DOHC .. 

 

 

[Justgrazing]

Couple of Parilla 2 stroke hori' singles .. Not as common as Pari' 4 strokes .. Check out the shape of the tank on the top bike ..

Next you are going to say you don't now who/what is Ilmor Engineering. Mario ILlien and Paul MORgan also from Northhamptonshire. Famous/infamous to tweaking Renault's F1 enguine for Red Bull among other things.

 

Ricardo? More into diesel that bikes or cars. Invented the Comet diesel pre-combustion swirl chamber enabling high speed diesels. Citroen used the Comet in the world's first production diesel passenger automobile 1934

 

 

 

 

I learn something everyday on this thread and channel thanks guys enjoying it greatly

At last, the answer to the age old question, what do you give the biker who had everything? 

[ballpoint]

A very nice looking Ace from ~1925

[ballpoint]

Meanwhile, in the German corner, a 1936 Zundapp KS500 that looks the business.

papa merely quoting Wikipedia here.

the 1917 aircraft engine would be rotary & radial

This video should be titled a ROTATING radial engine. Wikipedia is correct - a ROTARY engine has no pistons/valves , just a centrally rotating Reuleaux triangle.

My bird likes to come out for a ride 

.. And the recipe for the metal polish will go to the grave with me .. 

Flying Merkel ..

A 1926 Norton M18 500cc TT racer.  Good for the ton.  And nice to look at too.

 

I wish the bits on my Triumphs were as easy to get to.

You surely don't believe everything that Wikipedia says? 

 

Rotary aircraft engines pre-date Wankel engines.

Yamaha Fanboy 1.0

Another neat XSR700 custom, this time French.

One of my favourite currently available motorcycles.

 

Yamaha fanboy 2.0

Just been reading and watching the first official journo ride 'n' reviews of the eagerly awaited new Tenere 700 or T7.

IMHO prolly THE IDEAL bike for this country and at the top of my shopping list.

No electronics, amply power and torque, lightweight compared to the opposition, and it says Yamaha on the tank.

And Tenere....

8 and a 1/2k GBP in the UK. Keep it around 375-400k TB here and i may have to buy one.

This is 2019 m/c porn for me.

Seems like extreme overkill for Thailand.

[Justgrazing]

I ain't condoning this sort of thing but take a look as some in the Industry are saying this is part of the future of bikes ..

Top bike has a 3D printed frame though still a mock up at this time ..

Bottom one is also said to be 3D printed though that shape would be quite achievable in a conventional machine shop anyway .. The circular shape frame does make a lot of sense from an engineering point of view but is not easy to make aesthetically pleasing shall we say ..

5 axis millers and routers could theoretically make similar to the lattice one though i suspect would be quite time consuming ..

Que?

73 bhp

50 Ibs ft torque

204 kgs wet weight

is overkill?

I'll tell you what overkill is.

a 1250cc 250 kg 125 bhp GS bus masquerading as a touring bike capable of a bit of off road.

Not only is that overkill, it also contravenes the trades description act.
