Well, that's the CBT out the way. Next is to get my theory done and dusted ASAP, and then get booked up for a 5 day course - 3 days of training, MOD 1 on day four and MOD 2 a few days later.
Interestingly, I was talking to a couple of the trainers about the seat height issue, and they got me sitting on two of the test bikes (a Gladius 650, and an SV650). Incredibly, despite looking a bit intimidating they felt fairly small when sitting on them. My feet easily sat flat on the ground on both sides, so that's very, very reassuring in terms of the larger bikes on my test list.
