Buff Triumph's Rob Frost was caught out by a cold tyre and crashed out of fourth place in the Fuchs-Silkolene British Supersport race at Silverstone British Superbikes on Sunday.
 
Although uninjured in the crash Frosty, from Ruskington in Lincolnshire was left disappointed, as he had claimed a front row start to the race – his first front row since 2002 at Mallory Park.
 
The Buff Racing Triumph had been working well all weekend and the front row of the grid was made up from three Triumphs and a Yamaha.
 
As the race got underway Frosty retained his fourth place but was passed by fellow Lincolnshire rider Steve Plater on lap three. The safety car was deployed after a crash later in the lap and the riders slowed to follow it around the track for two laps.
 
Once the car had left the circuit the race was back on and Frost immediately went back past Plater into fourth place. But his progress was short-lived as he was caught out by a cold tyre and fell at Luffield on lap five.
 
A bitterly disappointed Rob Frost said: “I didn’t take into account that the tyre would have lost so much of its heat while we were following the course car and it caught me out. That’s a shame for both myself and the Buff Racing team as we had been so quick in qualifying and were anticipating a really good result here at Silverstone.”
