This is probably a dumb question but here goes. Looking on ebay for bar ends, I found em but also found grips with ends for same price.. upon further search I've noticed that some manufacturers list F1's all the way to F4's, but others only list F3's to F4's. My question is ( iI think I know the answer but need to be sure) do hand grips for all CBR's fit all years or are they different?

 

I'm pretty sure they all fit. But I'm not responsible for your stuff if it doesn't fit lol. I had to do some courageous buying with my bike too with stuff listed like that, luckily my stuff fit.

 

Yes I believe Bar Ends are all a common thread.
