The Wyberton-based G&S Racing Kawasaki team travelled to Brands Hatch for the final round of the National Superstock 1000 and 600 Championships but Tom Fisher and Kevin Van Leuven were unable to bring any points back home.
Fisher qualified well in 17th position and started his Stock 1000 race from the sixth row.
But on the first lap he was pushed down the order to 21st while the weather played its part in his performance as the track was slippery and damp.
Fisher was unhappy riding in the difficult conditions and after eight of the planned 14 laps he was down in 23rd place so decided to pull in to save the bike from possible damage if he crashed in the treacherous conditions.
The Stock 600 race was marred with crashes and a red flag.
Van Leuven began his race from a seventh row grid position but never really had a chance to move forward as the pace car was deployed for a multiple crash.
Once the car left the track it was only a couple of laps later that once again there was a multiple crash which this time brought out the red flag.
A new race was run over just six laps and with Van Leuven starting from 23rd position it was going to be an uphill battle to get anywhere near a point-scoring position.
But he got his head down and set about reeling in the riders ahead, moving forward on each lap until on the final lap he was up to 18th place.
Team manager Mark Fisher said: “The autumn weather spoilt the racing this weekend, not just for us but also for the rest of the riders.
“Tom qualified well in 17th place and recorded a personal best lap time at the circuit over the course of the weekend.
“But the slippery conditions made tyre choice a lottery and Tom did the right thing to retire from the race and bring the bike home safely instead of persevering out there and perhaps crashing and picking up an injury.
“Kevin never really stood a chance in his race. A six-lap dash from that far back on the grid was never going to see him pick up any championship points but he gave it his best shot and finished in a respectable 18th position.
“Thanks go to the team, staff and all our sponsors who have supported us throughout the season, we hope to work with you all again next year.
“We are well on the way to securing a rider for the Stock 600 class and we are 99 per cent certain of retaining Kevin who is to move up to the Stock 1000 class to ride alongside Tom next year.”
