Bridgestone's sole supply of tyres to the MotoGP paddock will remain unaffected to 2011, despite the company's decision to end its Formula 1 supply.

Twelve years after first entering Formula 1, the Japanese company announced today that it will end its agreement to supply tyres to the sport at the end of the 2010 season.

Stating the decision has come about as they address 'the impact of the continuing evolution of the business environment', Bridgestone maintain that it will still honour its contract to supply tyres to MotoGP until the end of the 2011 season.

Bridgestone won the tender to provide tyres to MotoGP last season when a change in the regulations stipulated that there would be just a single supplier. The contract would see them supply tyres to the end of the 2011 season.

Bridgestone scored its first MotoGP victory in 2004 when Makoto Tamada won the Brazilian Grand Prix at Rio de Janiero.
