TOCHIGI, Japan - Double MotoGP World champion Casey Stoner has slung a leg over a MotoGP machine again for the first time since he quit the sport in November 2012.He was at the TwinRing Motegi circuit this week but only as a test rider for Honda and even then bad weather affected his return for a Honda development test at the Twin Ring Motegi in Tochigi, Japan. The original plan was for Stoner to re-familiarise himself with the RC213V - 2013 machine during the morning and then test the 2014 prototype and a few other items during the afternoon. Unfortunately, after only six laps, rain arrived and halted testing for the day.'IT'S BEEN NINE MONTHS'Stoner: "It was good to get back on the bike, if only for a few laps! We only managed to get one run in before the rain arrived which was a little disappointing."It was really nice to get that first run - it's nine months since I've been on a bike and it's going to take me some time to get used to everything again!"The bike and the track felt good and I hope we can get some better testing when the rain stops and the track dries out."
