I run a 12 on my fiddy...
like "brap!" says, its added protection for your bike...
Its a problem on big bikes (street bikes like my F4i) when doing stoppies, cause it can "bite" ya...
Are yu doing stoppies?
But stoppies on the fiddy, being so small, its not so bad...
you'll get used to it, and learn to get yourself out of the way...
and the first time you "loop it" in a wheelie, just hit your rear brake HARD, and maybe you'll scrap that 12... haha....
If you do, make like you meant it, and thank the 12 bar for saving your plastic and your tail... :lol:
