I have done some searching and have not found any solid rotors for our Grizzlies, except for a company here in OZ that specializes in Motor Cycle brake components. They are called Metalgear International. I have spoken with them and they are keen to produce front and rear solid rotors if there is enough demand for them. They have already completed the front rotors, but have not had much call for them. As such they are reluctant to produce the rears. I believe that if they made the rears people would buy both front and rear. I know I wouldn’t just do the front solid rotors and leave the rears slotted.

Why solid rotors? I believe that the slotted rotors are responsible for the excessive brake pad wear we all experience when mud riding. I have chewed through a set of Race Driven pads in one 4 hour endure. Ok well they are down to under half thickness. I think the mud is getting into the slots and grinding away our pads. If the pads were solid then this may be reduced… Can anyone speak on this with any experience? or authority? Most on road vehicles have solid non slotted rotors. High performance vehicles and bike have drilled or slotted because of a phenomenon called gassing. I really don’t think our bikes brakes are getting hot enough to gas off the pads.
Maybe the solid rotors will be more prone to warping?

I have asked the company, if they do produce the rear rotors in a solid configuration, I’d be happy to trial them.
Would anyone else be interested in these rotors? or know of anyone in the States that are already doing this?

Cheers
