Mead & Tomkinson racing : ウィキペディア英語版
Mead & Tomkinson racing

Mead & Tomkinson was a motorcycle〔() BSA B50 racing, ''BSA advertisement'' "''Order your new 'M' regd. machine NOW from Mead and Tomkinson (Hereford) Ltd''" Retrieved 06 February 2014〕〔Motorcyclist Illustrated, March 1976, p.59 advertisement ''Mead and Tomkinson (Hereford) Ltd, Wye Bridge Garage, Hereford''. "''Mead and Tomkinson for Suzuki in Herefordshire''" Accessed 04 February 2014〕 and car dealership in Hereford and Tewkesbury. Three of the Tomkinsons, sons Chris and Patrick, and their father, Mike, successfully built and fielded racing motorcycles. They concentrated on the Isle of Man TT and on 24-hour and 8-hour endurance races at Spa, Barcelona, Thruxton and the Le Mans Bol d'Or. One of their riders was Neil Tuxworth (later head of Honda HRC UK racing team).
==Racing achievements==
A production-based BSA 441 cc Victor with race-styled control adaptations was first entered by Mead & Tomkinson in the April, 1967 ''Motor Cycle'' 500-miler endurance event at Brands Hatch ridden by Alan Peck and Tony Wood,〔''Motor Cycle'' 13 April 1967 pp.498-499 ''Britain's toughest race Motor Cycle 500-mile Grand Prix d'Endurance "''500 cc Class, T. Wood, A. Peck, BSA, Mead & Tomkinson''". Accessed 30 April 2015〕 followed by the Barcelona 24-hour race in September.〔''Motor Cycle'' 13 April 1967 p.464 ''Racing Line'' by ''David Dixon'' "''Interesting entry in the 500-miler is this 441 cc BSA Victor being wanged around Brands Hatch by Alan Peck. The model is also being entered, by Mead and Tompkinson (), in the Barcelona 24-hour race''". Accessed 29 April 2015〕
A race-prepared successor to the previous Victor model, a BSA B50 Gold Star 500 ridden by Nigel Rollason and Clive Brown, won the 500 cc class in the 1971 Thruxton 500-miler, a long-distance event for production road machines, completing 201 laps beating the second place Suzuki T500 with 194 laps.〔''Motorcycle Sport'', UK monthly magazine, July 1971, pp. 266–268. ''Thruxton 500''. Accessed 26 July 2015〕
Other 1971 successes were the Barcelona 24 hours (at the Montjuïc circuit), and the Zolder 24 hour race outright.
In 1973 Michael Tomkinson, having striven for an outright win at Barcelona since 1967 against larger-engine machines, had intended to enter two 500 cc BSA 'Gold Star' machines in the 'prototype' (track-based class) but a full entry list meant his bikes had to be de-tuned to road-type specification, running against larger race-bikes. Road-type Dunlop TT100 tyres were used in preference to racing tyres due to their longevity, combined with a rear chain oiler meaning a minimum of servicing was needed, mostly just regular fuel stops calculated on a 60 miles-per-UK-gallon basis and rider changes every two hours.〔 ''Motorcyclist Illustrated'', September 1973, pp.6-10 ''Barcelona 24 hour Endurance Race by Alan Peck.'' Accessed 10 May 2014〕
Tomkinson's race strategy was to have the two bikes circulating at different cadences, where whichever of the two was leading would employ a stategy of pressurising their nearest competitor, with the other bike circulating as a reserve without taking risks, hoping to pick up places if competitors succumbed to mechanical failure. Although this race-tactic worked at first, unfortunately the lead bike crashed-out in flames when ridden by Phil Gurner, partnered by Clive Brown. The second-string bike ridden by Nigel Rollason and Roger Bowler circulated steadily, achieving 686 laps in the 24-hours, finishing fourth overall (including and against machines in the 'prototype' class) and winning the 500 cc Production (road-machine) class.〔
A Mead & Tomkinson BSA B50 ridden by Phil Gurner once held the 500 cc class lap record in the 10-lap Production TT, set during the 1975 race when he finished in place 29 with co-rider Dave Savile.〔(TT Database, 1975 Production Race ) results]. Retrieved 10 May 2014〕〔(Archived ) Retrieved 03 February 2014〕
For 1974, Mike Tomkinson conceived a large-capacity endurance racer based on a 1000 cc Laverda 3C (as a 'test-bed' for a more-radical future build) with a modified frame to enable a lower riding position similar to the proven BSA profile, and using standard Laverda telescopic front forks. Other modifications were Laverda 750 SFC swinging-arm with disc-brake mounting and shorter Girling suspension units, smaller alternator with smaller battery both repositioned behind the cylinder block and a secondary 'emergency' fuel tank in the original battery position. Laverda provided crank parts and camshafts. All work was carried out by Mike and Chris Tomkinson at Mike's home workshop, to avoid disruption to their core retail business.〔, ''Motorcyclist Illustrated'', June 1974, p.21/24 ''The Endurance Racer takes shape, part two by Dave Minton.''
