The only arrogant people in the bike world are Harley owners.
They won't give you the secret-motorcycle-brotherhood-wave because you are not on a Harley.....so if you buy that CBR125 expect to be snubbed by the old school Harley types....
I do recommend taking a safety course though.
..and for the love of god.........buy a jacket! I slammed into a deer without a jacket on one of these....
So yeah..........unless you want nurses pulling gravel out of your festering wounds...........buy a jacket.
