Hi Mike, funnily enough i was 19 when i passed my test and now im 21 (in april) i have to wait until 08-08-08 (spooky date innit
) to ride a big bike (unless i paid 300 for the DAS), but fortunatly its not far away wahoooo....anyways more to the point...i tried EVERYONE i knew asking for a quicker way to do my big bike test or even ride one etc, but to no avail!!!
my only option would be to get a restricted big bike!!? quite good for experience! but still not what you want is it!
but as gaz said they change all the time and maybe there is something you can do, but i dont want to know as ill be pee'd i didnt find out about it earlier
!! lol
but yeah be good if you can!
good luck with it all
