In 1953 Perris sold both his old bikes to buy a new Triumph Grand Prix, winning his first race at Brands Hatch, with his growing experience enabling access to better machinery from established tuners-entrants John Viccars, Geoff Monty, Allen Dudley-Ward and Tom Kirby.
John Viccars provided for 1957 a pair of Ray Petty tuned Manx Norton's which Perris rode for five years throughout Europe until finishing third in the 1961 500 cc World Championship.
Perris then retired to South Africa running a business for two years but, with a hankering to race, returned to England entering the 1968 TT riding Suzukis for Eddie Crooks and again for half a season in 1969.
[5][6] Contracted in December 1971, Perris had to build a team from scratch using riders Peter Williams, Phil Read, Mick Grant and Dave Croxford.
Perris died on March 17, 2015, from a lengthy undisclosed illness, according to his daughter (although his long time friend and fellow racer Tommy Robb mentioned Alzheimer’s), with a funeral on April 1, 2015 at the Isle of Wight crematorium.
