Check out that polished half fairing ..

 

[Justgrazing]

This was up before but is a nice homage to a Vincent .. and the XV lump is the nearest out of Japan to resemble a Vincent engine .. which is why they are sought after by bike builders ..

The Bullet, which started as a derelict 1950 Thunderbird frame and engine:

Pre unit mate.

So pre 63.

Fair chance the top end of the motor is 9 stud '70, and mebbe got a '70 crank and rods in it. all doable.

But that is a P/U bottom end.

However, the bike has some nicely done, UNUSUAL touches.

The weird timing cover with extension piece,

the use of a front half unit primary cover, with a pre unit rear half - very neat,

Jap 6 spring clutch.

I like the colour details and contrast on the rims and front brake.

Stored pics in my computer files, ta.

According to their site:

The Kestrel started as the unit engine of a 1970 Triumph Bonneville, which was cut in half & re-engineered. With the exception of a few critical pieces everything – including the frame, front forks, gas & oil tanks, exhausts, handlebars, levers, even the cylinders – was fabricated in-house.

Rare reverse cyl liquid cooled 250 MZ from the mid 60's .. 

Mid 50's 350 .. MZ's take on the flat twin .. 

TS125 cooled out East German style .. ( should drop the stickers and insulting tape across the headlight ) ..

Sorry, i'm looking at the pics, but i don't see it.

I don't understand the fwd extension on the timing cover, as i can't see anything externally being driven from it.

The rear extension to the timing cover could be a modified electric start ES timing cover driving a mag possibly?

And even if it was a unit once, why?

I mean, i'm one to talk, to this day i don't think any one has ever put an all iron 8 stud top end on a unit bottom end, but there was a method to my madness....

I'll have a look at their website later.

Cheers.

 

Edit.

So i just looked at their hipster clever website.

I repeat, W H Y ?

You are correct, it is a 70 unit motor with the box band sawed off.

Then one off alloy CNC machined barrels made (why?).

Then a unit timing cover fabricated to look like a P/U one. Why?

I could go on, and on, but it'll make me look like a d##k, so i won't.

Nice bike....

Top bike is a rare Yamaha 450 2-Trac 2 wheel drive with a Dakar style headlamp fairing ..

Couple of modded DT250's ..

RZ250 .. A YPVS lump in a trellis frame .. This one has been cooled out with a bit of bodywork ..

The carrier operated Hawker Seafury .. Not as well known as some of the other WW2 darlings this was by the hand of Sid' Camm who designed the Typhoon which is why there are similarities from the wings back t'wixt the Fury and Tiffy .. What makes this unusual for a Brit' fighter was the Bristol Centaurus 18 banger radial engine over the Typhoon's Napier Sabre 24 cyl .. Radials are generally more complicated to build and bigger ones more prone to overheating than more conventional engines and Brit designers always seemed to prefer liquid cooled Vee lumps .. that makes this plane the only British fighter of that time I can think of that had a radial .. but it obviously worked as the Fury ended the war as one of the fastest piston engined planes at 460 mph .. it was also heavily armed with four 20 mm auto cannons plus the usual array of direct fire rockets and bombs that they were all kitted with by then ..

Yamaha RZ or R1-Z to give it its official moniker .. which caused confusion when they called their later 1 litre Sports job an R1 also .. 

so these were always referred to these as RZ's .. either way a YPVS lump in a trellis frame ..

If I put those bars on and removed my NSR fairing I might ride it a bit more. I wonder what front end I would need?

When I traveled with the carnival back in the ‘80’s, an independent’s son had a 3-wheel HD golf cart powered by a KZ-1100.

When I saw him the next year he had it in a 4-wheel cart...

My uncle had a Black Shadow. He could only afford it, because he worked tax-free in Hong Kong.

Could some one please explain to me the reasoning for the plenum that the pipes go into and the tail pipe comes out of. Is it just for the look or a technical reason . I have never seen anything like this before. Thank in advance Randell

As Mogandave has already mentioned it could be a catalytic converter .. The bike looks like it may have fuel injection and if that is the case and it is a " closed loop " system then a cat' and lambda sensor are needed to monitor and clean up the emissions output .. But could possibly be just following the latest fashion of a collector silencer with short exit pipe/stub .. Buells had something not dissimilar for yrs though the Bu' silencer looked like it had been nicked offa truck ..

Dinky little Diamant and a bit of Diamant tank art ..

Like many motorcycle manufacturers from days gone by Motosacoche founded 1899 never got past the late 50's .. the 250 Opti proddie racer below is one of the  last of them .. which is a shame as their early bikes es'pesh the Vee twins are quite superb machines ..
