Brighton Speed Trials 11th September 2010 | |||||||||||||||||||||||||||||||||||||||
As an alternative to a sunny race at Cadwell Park a select few chose to take in some seasonal English seaside weather down in Brighton for the eponymous Speed Trials. The 500cc class hasn’t been well supported in recent years but this time a triumvirate gathered for the standing ¼ mile blast, namely Hakan Sandberg (JBS-Norton), John Potts (Monaco-Norton) and James Holland (Cooper-JAP Mk VIII). A welcome addition came in the form of Brian Joliffe’s “Hell’s Hammers”, the ex Wally Cuff Cooper Mk VI V-twin.
There were intermittent light showers during practice so the course was damp for our one and only practice run with a marked lack of grip at the start. The course is now rather bumpy and the combination of that and a breeze throws a 500 around quite a bit so commitment is required to make a good time. The extra capacity of Brian Joliffe’s Cooper twin was telling and he posted the quickest practice time of 15.23 seconds with a terminal speed of 93mph. Interestingly the quickest 500 was faster over the first 64 feet in 2.75 to the twin’s 2.93 seconds. However the 500 only managed 16.23 secs for the ¼ mile with a terminal speed of 83 mph; 6,000 rpm in top gear being reached crossing the line. Hakan posted 17.32 seconds and 77mph over the line using circuit gearing in the JBS and John set 18.73 seconds and 63 mph in the Monaco.
