Ok, as I'm chopping my bike I find myself shopping for a new fender.
I'm looking at one like this:
SIGNATURE 6.5" RIGID REAR FENDER


The one I currently have is the stock 01 fender:


I am currently running a 140/90/ 15 and have about 3/4" of room on either side of the tire within the fender.

I have determined through other numorus threads on the subject that a 150/90 15 will fit.

Here is the question. If I am planning on putting on a 150 is a 6.5" fender wide enough, too wide, or just right?

Am I putting the cart before the horse? Should I just order the fender cause that's the one I want then fit the tire to the fender?

Thanks for your responses.

That's what I needed to see. Thank you sir.
