Two-time World Superbike Champion James Toseland has announced his retirement from racing as his long-standing wrist injury means it is no longer safe for him to ride competitively.

The former MotoGP rider badly broke his wrist in a testing crash at Motorland Aragon earlier in the year and, despite the best medical attention, it has never fully healed.

"2011 has been a tough year for me and this week has been one of the most difficult of my life, but advice from professionals has made it clear that my crash at Aragon has left me with a permanent disability, which means that I will never again be able to ride competently at this level," said Toseland.

“While that’s hard to hear, I have to place the emphasis on the safety of other riders in the paddock as well as myself and I realise that it’s not fair to occupy a World Superbike seat with a team as professional as BMW Motorrad Italia when there are fit and talented riders available who are desperate for this type of opportunity.

“I’ve been extremely fortunate to have enjoyed a long and successful career doing something I love and I’m really grateful for that. I’ve been lucky enough to bounce back from serious injuries in the past and I’ve had the support of a great family, brilliant friends and a fantastic fanbase to see me through the highs and lows. I’d like to thank the BMW Motorrad Italia team for their suport and understanding and all of the personal sponsors who have remained loyal to me, including MMCG, Henderson and Bennetts.

“I hope that the team can find a replacement who is able to do justice to the bike and the people working on it. I hadn’t expected my retirement to come at this time or in this way and I’m extremely sad to be leaving racing behind, but I still have the memories of the amazing opportunities and success that this career has provided me with.”
