Hi,I just passed my cbt last weekend & just been out for my 1st ride after getting my bike taxed which was awesome. 
 
Im going for the DA too but going to ride about for a few months and take it in the spring as being a car driver for over 15 years i feel very exposed! 
 
I'm 6ft 2 and riding an xv125 which seems ok & is nice and heavy which im hoping will help with jumping on the 500 for the DA.
