sucks for you 2big. im sure u would pass easy on a bigger bike so your size and age are against you. id go for the hire option if i was you. if you change your front sprocket you will have to change your chain too and then you might want to change them back after your test if your keeping it for 2 years. i think you can do mod 1 on hire bike and mod 2 on you own
had to sit a driving test to get to drive a company van for britsh gas he said i drove well but my observation and indercation was under par flipin cheak !
I passed mod 1 and mod 2 first time in august this year, so i still probably ride more or less as i was taught, so yes i could probably still pass now.
Glad i don't have to though!
Oh, and the swerve test is really easy when it comes to it. I found the hardest thing was the figure 8s. I had to do it on a Yamaha XJ6 which is, with apologies to anyone riding one, a truly horrible bike :p Way too top heavy to my mind. Also, when the feck am I ever going to need to do a figure 8 in the real world??
