“Kocinski recuperating after test accident

“Yamaha test rider John Kocinski is recovering well after successful surgery to repair a broken lower left arm, which he sustained in a crash during testing of the YZR-M1 in Barcelona yesterday, Thursday 21st June. Kocinski had almost completed the third and final day of testing when the accident took place, in which water leaked onto the rear tire from a split hose in the cooling system. The attending surgeon reported that the operation passed without complication and that Kocinski should be fit to return to testing in approximately one month.”
