heres my opinion on it - you may think youre cautious and have control, but you have no idea until you're on the bike.
i have a buddy thats ridden for years (started on dirtbikes and then went to a 883 sportster and recently bought a RC51), plenty of experience. he wrecked his bike this past weekend. too much speed going into a curve was the first part of the problem and then too much brake...
yes, you can have too much brake, thats when people flip over the handlebars.
dude, dont get more than a 600, unless of course its like a 1985 750 or something lol.
if this is your first street bike you need to be able to handle it well, its going to be a lot different than you think.
lightspeed - you give horrible advice....
