" yeppers, those bikes are road legal " however I haver for a RD . the 350 might be to fast . Better settle for a 250 I think . ( barff Icon ) :p

" I had a veglia recollection of an article on in an old BIKE magazine about a fellow who built a big Trident for sprints and land speed competition. A post to the www.triplesonline.com forum not only jogged my memory that it was Alistair Laurie (from Dalbeattie, Dumfries, which I think may be in Scotland) who built and rode the bike, but also resulted in some photos of the bike that were taken by various people on the forum.

The article was from the August 1979 issue of BIKE, and was written by Dave Calderwood. Laurie's bike had a custom crankshaft made from EN40 steel with a longer stroke of 80.5mm, as when combined with his own big-bore barrels the engine displaced 998cc. The crankshaft was nitrided and weighed in at 7.5 pounds less than the standard item (which is no lightweight). The engine also had tuftrided EN24 steel connecting rods with Cosworth F1 bearing shells. 33mm Amal carbs, bigger valves and 1.625" exhaust headers. The bigger valves fouled each other so he had to reangle the guides in the head, and replace the valve seats. The crankcases had to be opened up for the bigger crankshaft, and then the rods were installed with the rod nuts tightened through the sump plate. The two plate clutch uses his own sintered bronze driving plate.

A magneto was driven from the inlet camshaft via a timing belt at 2/3 engine speed. Laurie also built his own North-style frame, and was going to use a dustbin fairing for the LSR runs

I recognized the wheels on Laurie's bike as being made by Eric Offenstadt, and since Tony Foale was the UK distributor for them I asked Tony if he remembered selling them to Laurie. Tony did, and he also told me: "I certainly do remember selling them to him. He had magnesium wheels and was the only person that ever came back and asked me to machine them thinner to save weight. He was a great craftsman, he made the alloy tank and seat unit himself. I think that he wanted to break 200 mph. I have a vague recollection that he might have done it with a dustbin fairing. The bike ended up very light, even by my standards; he was fanatical about the weight of each piece."

obviously on his computor game . :D
 
Plenty of show pony pix there Matt, any evidence of performance that does not beggar belief?
Will it do ~"45 mpg" while double tonning it at the I.o.M.?
