is it very difficult to get a B full licence?

I am planning to get a licence, but I am unsure of which one to go for, B2 or B full? any advice?

Are they significantly different from each other during the class?
I know, practice makes perfect....

not for me, told the institute and the instructor i have never rode a bike before and only 3 times as pillion rider and they told me to go with the er6n, adrenalin rush all the time 

hahaha this i'm not sure.....

but, when i was a kid, i always dreamt of having my own, but being brought up in a cainis family, you know lah....

until recent years when i have an eye on fun bike, i've always been wanting to get one,  due to various reasons, it was withheld until now.

until recently, i got a new number plate for some reason (i already have a car, 2 yo, so I'm not changing car, and my number plate on my car is also very nice one), so i have this spare plate that I will need to put it onto a motor within few months. so this renewed my interests in getting a fun bike.

found one last week, booked it and probably bringing it back in the next 1-2 weeks.

now, one thing i'm not too sure is if i would get myself a larger bike in the future 

P/S: i booked the smallest z series and i've been looking into the larger ones now. LOL..........
