Checa to quit MotoGP

Spanish rider Carlos Checa will leave MotoGP at the end of the season to ride for the Honda Ten Kate team in the World Superbike series, he announced on his Web site (www.carloscheca.com) on Tuesday. "I'm looking forward to this new challenge," Checa said. "It's a great opportunity as I know my results won't be hampered by technical difficulties as has been the case for the past two years," added Checa, who will be replaced at the LCR Honda MotoGP team by Frenchman Randy De Puniet.
