Not quite, the bike is a bit of a make over special, it started life in 1962 as a 3TA. Then in 1971 the engine was replaced with a rebuilt 1958 unit and the bike modded and re-registered as a Tiger 90. It has now had new barrels and a rebuilt head and twin carbs, taking it up to 500cc.
Just doing a bit of tidying up work on it now, new handle bars etc. Then it's ride the hell out of it this summer before a winter strip down and full rebuild.
