Wait till you're 25.
I got quotes on my bike the day before and the on the day I turned 25 and you wouldn't believe the difference! Try it out by changing your DOB on quotes.....
I bought a ZX-6R Ninja (the P7F model) this april for my first bike. It's got a very sporty stance and racey looking. It's certainly quick enough for me.......
A lot of people said it was too fast for a first bike, maybe true however it's all in the right wrist. Nobody forces you to open the throttle all the way!
Have a look at what you like style wise and then try different bikes out. See what you like to ride!
Oh yeah, Lomoto will help you out a lot! It's his livelihood and he can advise you!
What you want to use the bike for?
