The morning of my CBT was fine (had already done one 4 years earlier on a moped) Went out on the road ride and found that I kept stalling the bike. All 3 of us were asked to come back to finish our road rides. Went back to see a different instructor, who happens to be a family friend, he took me out and 10 minutes into it i stalled at a mini roundabout...Guy behind me hadn't noticed me and hit me. Was stuck under bike and pretty shaken up, luckily no injuries and bike was fine. Pretty big dent in guys citroen picasso tho Got my certificate that day too, apparently only because it wasn't my fault and I'd ridden well for 2 hours after that. Never stalled since at a roundabout though. I'm always extra cautious now
