Is it a circuit racing bike he's making or a straighliner? If the latter I can't see it making much difference!
A straightliner. Metisse have raked out the forks to give it better stability at high speed, though I doubt the standard geometry is going to cause any excitement at 80 odd mph.

Only just turned it on. What's this 80mph land speed record?
At a guess (missed a bit then) it'll be an obscure 350cc overhead valve 1930s record! There's many vintage racing bikes that are far faster than that from that era, our late 1920s (albeit overhead cam) Velocette KTT will do that. And I followed my brother on dad's 1928 ex-race AJS at a fairly comfy 60mph overtaking traffic last weekend, which makes me think it must be an odd class!When I looked into Bonneville a few years back I was amazed at how many potential classes there are, and some of them are really quite low. Guess they're the ones nobody's had a decent crack at lately.

Ahh, was thinking it must be some strange, old record. Cheers.When I looked into Bonneville a few years back I was amazed at how many potential classes there are, and some of them are really quite low. Guess they're the ones nobody's had a decent crack at lately.
There needs to be more motorbike program's on television.

They should have done the full hour on the girlie doing 264mph. Things never really look fast on telly but oh my gawd she was flying.

Which bike won best bike at the posh show? I couldn't quite make it out. Was it the two boy-band fellas? I thought theirs was the best personally.
The two young chaps won the 'most striking' category, the Metisse won the best 'racing' motorcycle.264mph on the Hayabusa - you could hear that ripping the air apart alright!
There must be more to the class rules than just 350cc and pre-55. I'm fairly sure the average 350cc TT lap was 80mph+ by 1955 so they must've been going a fair bit faster than young Henry on the straights. Get a Manx Norton and it'd easily be faster!
Still nice to see something different on TV

and old Etonian. I wondered how he could afford that huge house in Oxfordshire. Apart from his changing accent the show features some nice machinery and is worth a gander.BigTom85 said:
Really enjoyed last nights episode. His bike really does look delightful, and some of the other bikes were bonkers. 8.0 V10 anyone?
He did some realy good other specials http://thekneeslider.com/two-allen-millyard-specia...srob said:

You could use something a lot more humble than a Manx. A ride to work BSA and a bit of time in the workshop should suffice. Still nice to see something different on TV
According to Roland Pike (who knew a bit about BSA singles):
The B31 for example always gave at least 17bhp often more. The B33 500cc standard engine was another consistent performer giving 22 - 23bhp when new... ...The B31 was a good little engine, a 350cc single, with cast iron head and cylinder. By fitting a few Gold Star parts they were easy to improve. By merely fitting Gold Star cams (touring version) and a Gold Star silencer they would put out 23bhp. By going a little further, fitting eccentric rocker spindles, lighter push rods and tappets, shorter connecting rod, shortened cylinder to suit, Gold Star piston giving 8:1 compression in place of 6.5:1, they would give 27bhp and almost 100mph, at no extra cost since these were all production parts. The B33 500 was much the same and could easily give over 30bhp.

So if anyone fancies responding to Henry's challenge...
