I'm looking over a buds new to him bike, & see a chunk misssing from the mid mount, of the exhaust(stock) frame.
So, the pipe has the rubber mt. the bolt,if it was there, would thread into 'this'.
My Q is, would someone have removed this to install an aftermarket pipe?? 2006 CBR600.
The bike has crashed 'softly' , enough so as to only crack the left foot peg bracket, & they didn't replace it..
