Today I had my mod 2 and unfortunately failed with one major. We approached a junction on a 20mph road and was indicating to take a right onto another 20mph road on my approach I did what I thought was expected and thought I had dropped to 1st gear for the turn, I was in 2nd and clumsily my left foot came off the peg for a brief second as the bike staggered and I quickly changed down and carried on safety. I instantly knew what I had done and kicked myself. this was my fail, the examiner said I didn’t have control of the bike,in My opinion I did, I didn’t stall the bike and the error was over in the blink of an eye my instructor said this was very harsh decision as I only had a couple of minors one of which was nervously catching the horn when cancelling a signal indicator.
