One of the first to see the competition potential of BSA-Triumph's new three-cylinder 750 was Stan Shenton of the Boyer of Bromley dealership, who began preparing machines for his two riders David Nixon and Peter Butler over the winter of 1968/69. Weight saving was a priority, so a Colin Seeley alloy fuel tank and a glassfibre racing seat from Fi-Glass of Edenbridge were fitted. A Fontana 250mm 4LS front brake replaced the factory item, a Quaife five-speed gear cluster was substituted for the stock four-speeder, and the clutch suitably lightened and balanced. When they became available to selected entrants in 1970, the works-developed 'short frame' was used, giving greater ground clearance.

Engine development was entrusted to Bob Gaynor of Piper Cams, for whom Nixon worked. The tuning carried out is extensively detailed in Stan Shenton's book 'Triumph Tuning', which is still referred to by home tuners (copy available). An ignition system was developed in collaboration with Ernie Bransden and has remained in production to this day. The suspension was re-valved and alloy wheel rims fitted while a fairing completed the job. All the modified parts were homologated by Triumph and complied with A-CU rules. Boyer's modified Trident production racers often beat the works team, which didn't always please Triumph. The Boyer Trident won first time out at Snetterton and Nixon won most of the Shell Oil Production Race Championship rounds to take the title. Although a Boyer Trident never won an Isle of Man TT, John Williams finished second on one in 1973 with David Nixon coming home third.

The Boyer Trident's present owner is Carl Rosner, who grew up with David Nixon in Sanderstead, Surrey, sharing the same passion for motorcycles. They passed their tests the same year and both bought AJS 350 singles and raced each other on the-roads. The pair built a BSA Gold Star racer but Carl didn't take to it as David did and changed to four wheels, racing an MG Midget. David went on to become a successful motorcycle racer but lost his life when he crashed at Laurel Bank in the 1974 Production TT, won that year by Mike Grant on the famous works Trident 'Slippery Sam'.

In 1988 Carl was offered David Nixon's Boyer Trident, which was languishing in a garage
just two miles up the road. The owner had bought it from Stan Shenton, raced it for a few seasons
and then laid it up. Carl could not believe his luck as the Triumph was totally original, and soon had it back at his motorcycle shop in Croydon.

Back at the shop the Trident was stripped down, worn engine parts replaced, some tuning improvements carried out, the frame and cycle parts refurbished, and a fresh set of racing tyres fitted. A new wiring loom was made and the latest Boyer ignition replaced the original, possibly one of the first made and which Carl still has. The original Quaife five-speed gear set was found to be in perfect condition.

All that was needed now was a rider good enough to do justice to the Trident on the track. Carl turned to the evergreen racer/journalist Ray Knight, who had been racing Triumphs for years and won the Isle of Man Production TT's 500 class in 1968 on a Daytona, plus many other successes both at home and abroad. Classic Racer magazine heard about the resurrected Trident and John Ruth track-tested the bike at Brands Hatch for an article entitled 'Back Where It Belongs', which appeared in the Winter 1989 edition (copy available). Ray was no stranger to racing Tridents as he had ridden for Hughes, another of Triumph's favoured dealer teams, and raced his own Trident successfully. Coincidentally, Stan Shenton had loaned Ray this Boyer Trident to race at Snetterton for a test report published in Motorcyclist magazine (photocopy available).

The Trident was entered in the CRMC's Group 3 Production Class and raced every season for the next five years, battling against the likes of Alex George and Alan Walsh, and usually finishing in the top three. Carl cannot remember it ever failing to finish and Ray always brought it back in one piece, although he had some close shaves. After Ray moved to the Isle of Man, the Trident continued to be raced by trusted friends and in 1998 came third in the CRMC 750 Production Championship in the capable hands of Roger Imberg. It was a particular good year for the Rosner Racing Tridents, with Roger's son Danny winning the CRMC F750 Championship on board Carl's Rob North-framed Trident (Lot 454).

Little changed from the day it emerged from the Boyer race shop some 40-plus years ago, the Trident has been kept on display in Carl's showroom for the past 6-7 years and is offered fresh from a winter rebuild. Described as 'ready to race', this historic racing motorcycle is offered with assorted magazines, dynamometer printout (75bhp at 8,000rpm), a selection of period photographs and CRMC Machine Registration Certificate.
