Hi guys,I reckon I might be able to put my rebuilt 59 golden Flash through the german MOT(TÃœV)in Febuary,however there are 3 questions they want answered and also want proof that these answers were the standard in 1959 (how anyone can prove that must be almost impossible or ??)
Question 1.what is the border (height distance ?) of the motorbikes headlight at night (2.5 meters on a vertical wall ?? for example )2,What is the output/ power at certain revs ? 3,what is the loudless recording/allowance (measured only in good weather. Would be very thankfull if anyone could even point me in the right direction,thank you.

Standard A10 power output = 35 BHP @ 5800 RPM. The noise level on a Flash would be subjective in the U.K. and subject to the testers judgement. Noise levels for older bikes are usually not an issue with most testers unless it unreasonably loud. You will find a high level of tolerance and a sympathetic attitude at most testing stations. Seek out a classic bike friendly one.
According to the Haynes A10 manual "UK lighting regulations stipulate that the lighting system must be arranged so that light does not dazzle a person standing in the same horizontal plane as the vehicle at a distance of 25 yards from the lamp. The method of setting up is for the rider to be seated on the machine and that the main beam centre of the beam should be the same height as the headlamp". Not very scientific but that is how it should be done, as you can see there is no predetermined setting because the riders weight and spring strength will influence the result.

Hello Stephen!
I got an Austrian "Einzelgenehmigung" for my '56 Flash last year. If it helps you, I can send you a copy of the document via email. At least the noise level is in there (101 dBA Standgeräusch). I guess the German TÜV will accept an official Austrian document as proof?
They didn't care about the other two points you mentioned, but they wanted to see was a passenger grabrail or a band around the seat (your belt works well for this *smile*) and they needed proof about the top speed (because of the tire type, had to call an approved expert, Sachverständiger in German, to tell them).
Oh, yes, they also didn't like the side stand, because it doesn't return by itself, so I just took it off right there.
And the guy thought it was a good idea to take it out for a test ride. I nearly burst in laughter when it kicked back and bit his leg *smile*
Regards, Markus

Thanks a101960,I need to write that down.Yes Marcus that would be great,I´m awaiting a trying time after it took me over 3 months of phone calling and letter writing,just to get a proxy document from the brits and germans to allow my bike even to be examined after the bike docs were not released by DVLA Swansea(althought they told me to return them no problem,and I´d get new ones,anyway long story,so much for EU co-op).Here is my @ Stephen.Smith@gmx.de cheers

OK, I'll make a scan of the docs within the next few days and send you an email. The Austrian authorities partly also accept books, manuals or even information from the internet as proof for certain points. Don't know what the situation in Germany is like.
BTW, I had to mount a mirror and a red reflector on the rear mudguard. Better ask the TÃœV-guys. Its these little things that can make you return home without your papers, if they want to.

Its funny what they can be fussy about.
The Finnish inspector, who looked at mine when I was registering it, was preoccupied with the wheelbase length (so that it didnt become a chopper afterwards) and handlebar width(!)He wasnt that keen that it had an 18" back rim fitted-The only reason he knew it should have a 19 was due to reading the BSA instruction manual I had brought with me.
He also drew me up on it not being fitted with a mirror (I'd removed it so I could get it out the shed)Then decided it didn't matter for bikes manufactured before 1960. He didnt mind the VW Beetle silencers and commented it was quieter than he expected.
It all went quite smoothly. I was worried because the bike wasnt standard.
Cheers,
Iain

Yeah, all rather ridiculous. The funniest part was when the secretary there came into the workshop to see the bike, because she heard that "great engine sound". This was approx. 2 minutes after the guys started arguing about the noise level. That discussion found a sudden end after the visit of the nice young lady. *smile*

you carnt beat the sound of an old brit bike *smile*

Even my wife agrees with that! It's true though. The sound is instantly recognisable, and where ever you go heads turn as you pass. A Brit bike working hard is simply amazing. When I use my bike for work I pass over two railway bridges, and the sound of the exhaust bouncing off of the bridge walls is awe inspiring. I can never make up my mind which is best. Hard acceleration or the sound of the over run as I decelerate. There has been more than a few times when I have had a car driver ask me to give it some "wellie" when the lights change and I pull away. For the benefit of our American cousins "wellie" means Wellington Boot i.e. "put your foot down" or step on the gas.

G'day all, when I rego'd my '51 back in '84 they wanted a brake light. I asked the inspector to ring the tech dpt and showed him the manual showing a break light was an extra and not std fitment. He passed it and said "good luck". I have since fitted one, it works better than the brakes. I have never been pinged for noise, all my bikes run unrestricted. The sound of the cafe's empty reverse cone megaphones is awesome, better than any HD around here. At least if they (tin tops) can't see me thet WILL hear me.
Cheers
PS Bah Humbug. Its peak holiday time down here, every 2nd car has blue & red lights.
