1940 Triumph 3SW 250 JAP grasstrack speedway For Sale

This bike started life as a part of a War Department order from Triumph of 10k side valve 350s. They were delivered in batches of a thousand - this one in the Home Counties somewhere and I suspect it never left. The SW was a sv version of the ohv Tiger 70, 80 and 90 pre-war Triumph single. After the war the light frames were popular with grass trackers and this one was owned by a chap named George Bason, who was a speedway rider and builder. Someone (likely George) gave it small tanks, chunky tyres, a rigid saddle and the smaller but better JAP 250 ohv engine. The engine has two numbers and a BSA conrod, so was clearly built from parts - one dates from 1934. I bought the bike in 2015 from George's brother. I got it registered with an age related plate, carb refurbished by Joe The Carb, big end from Godden Engineering, valves and guides from Speedway Services, frame and a lot of sundries powder-coated, new controls and cables, a few missing parts (kick start, left peg, more road biased handlebars) sourced. I built it up for the road as a cheapo intro to classic motorcycling. I think it's quite a pretty little bike and educational as you can see how everything works. It's very rideable on the road for an 80 year old, jetting and gearing are good, it's easy to kick over and starts quickly. Since rebuilding I've probably done a dozen days out of 70-90 miles - 800 miles maybe. I'm riding mainly with friends on 500s, so it gets ridden insistently to keep up. Frame, forks, hubs, and gearbox are as original to the model. Fuel and oil tanks, engine, exhaust and saddle are customisations - presumably as George built it in 50s/ 60s. (I have added springs to his saddle). Although I made it for the road and weekend ride outs I like that it wears its grass track history. A cheap, rideable intro to classic biking for a youngster, an easy starter for an older rider, or even a restoration to military spec project. There are forums for that of course and both repro and some original stuff available. I've moved on to a Sunbeam and I don't have room for two, but I know already this will be one of those bikes I will always regret selling.
