April 12th 2005.
The British Supermoto Championship has announced that Naturally Best (Vivaldi) is its 2005 title sponsor. 
The Championship will be referred to as the Vivaldi British Supermoto Championship, marking further racing involvement by the Lincolnshire-based potato company. The Naturally Best motorsport portfolio now encompasses British Superbike and National Superstock Championships, Formula Ford and British Touring car, plus support of May's Thundersprint Classic, to be held in Northwich, Cheshire. (All the above activities are under the Umbrella of Vivaldi Racing Ltd.)
Eddie Nelson from the British Supermoto Championship said: "We have seen what the Vivaldi racing team has done in British Superbikes, establishing themselves as one of the biggest and best-presented teams in the paddock. The British Supermoto Championship will be working closely with Vivaldi to raise awareness of their unique potato while building the profile of the sport."
Apparently, the Vivaldi Potato has become renowned for its texture and buttery taste, and we are told that 'tasting is believing'. If you want to try some, they're available from selected Sainsbury stores.
