For 1981 he built up a 1959 engined 500cc Royal Enfield Bullet, mounted in a Colin Seeley frame, to compete in the unlimited single cylinder Kenning "S" series, and to make his debut at the Isle of Man Manx Grand Prix.

He was moderately successful on this bike on the short circuits, but it was in the Isle of Man that he stunned his opposition and all spectators by finishing in an astonishing second place in the newcomer's race at an average speed of 94.87 mph.

Some notable performances include sixth place in the Formula One main race at the 1995 Isle of Man TT on a hub centre steered Yamaha GTS - definitely not a racing machine - and in the 1996 Isle of Man TT setting the fastest ever lap on a British bike at over 114 mph on a Saxon-framed Triumph.

More recently Linsdell rode the only two stroke at the Centenary 2007 Isle of Man TT, on board a rare 500cc former GP bike - an Italian Paton from 2001.

Linsdell also scored points in various rounds of the Formula TT world championship, beating many regulars on home backed machinery.
