Silly question but where have they hidden the electrics and the oil? Looks the business.

Following the pipes oil tank is under the fuel tank.

Silly question: where may you ride it?
cheers, Uli

I'm gugob the essing the fuel tank has an internal compartment that is the oil tank, and at a guess, the minimal wiring is hidden in the outer sleeve of the oil line.

If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

And So after 9 months of design and planning and building, my bike has been finished.
 I have done none of this myself.  :D



Wow, what a superb looking machine, they have made a fantastic job of that, a real head turner, well done!

Thank you all.
 It took none of my sweat and tears, but great collaboration and design.

The oil tank is hidden on the inside of the right side of the petrol tank. A really nice bit of fabrication with a loss of fuel capacity, but lets not kid myself that this is a long distance tourer.
 Rear hump houses a new lithium battery.
 A motogadget M-Unit takes care of all the wiring for various devices and most of the wiring back to front is buried inside the frame tubing.
 It is , up close, once of the nicest custom builds I've ever seen, and that's not just because it's now mine.

The bike will be run for the first time this week and then off for its M.O.T and I'll be on it very soon.
Though as most of the engine is new inside it'll need some running on, especially as the crank shaft had to be remade.

It's not a silly question at all. I'll ride it anywhere I like. Only the small seat will restrict me. :)
It's not a garage piece just to look at. It was always going to be fully functioning and road worthy.

The estimation is that the power output is up about 50% but can't fully sure until it's run in then put on a Dyno for a full test. Capacity went from 750 cc to 836 cc anyway.

So it is even street legal?

Best looking 750 cafe racer I have seen. Great you did not go for a ugly upside down fork and kept the old style.
cheers, Uli

Of course it's street legal.  :)
 I have a headlight, horn, indicators, registration, road tax, road tyres. Everything it needs.
There might be a question over the size of the number plate when it's fitted, but I'll distract the policeman by showing him the rest of my shiny bike.

The style is not my personal cup of tea but liking the clean uncluttered lines. Very neat.
Can you give us some more pics from different angles please so we can see more of the workmanship.

Really different, very good engineering and design skills there. Like the gunmetal type paint job.

Only thing that I think of that made me pay attention more was the front brake bolts. I've done a similar thing to a car I modded a few years ago and whilst the bolts holding the caliper to the spacer bracket look high tensile the ones holding the bracket to the fork leg don't. Are they stamped high tensile eg 10.1 or are they just standard bolts and nuts? if so you may want to have a look at that as they could sheer under braking and you really don't want that  :) Not a criticism just a potential safety issue.
Don't play stupid with me, I'm better at it

You might have more of a problem with the noise! , I think this can be read as our bikes don't have noise limitations though, stick a copy under the seat 😄
Just highlight the misleading bits the average cop will fall for it !

No electric starter?
Hence a kickstart!
