I was wondering if anyone has thought about using a rear caliper from a 250 dirtbike? My buddy has a 93 CR250 and the thickness and surface area of the pads is much more substantial then anything I've seen on the rear of a quad. This seems like an easy fix to going through rear pads 2-3 times faster then the fronts. I realize it would take some custom bracket but I think it would be worth it. I would try and locate a caliper from one of those used parts places. Just a thought, any opinions appreciated.



93' Mojave: Supertrapp, Ported head, 11.5:1 piston

 

I have also been wondering about that swap.
Anybody tried this swap?

From comparing a dirt bike caliper and an ATV caliper, I don't see any reason why a dirt bike caliper wouldn't work. Like Jeff said, you would need a custom bracket.

 

Actually I would use a front caliper off of a dirtbike (most have two pistons). Or if you wanted really good stopping power get a front caliper off of a 600 or bigger crotch rocket most have three or four pistons per caliper and they have dual discs up front.

 

I called a couple used bike parts dealers, one place told me $60 for a CR caliper and another place told me $90 for a 93 KX caliper. Still thinking about it.

 

I used to read dirt bike magazines up until 3 months ago. In the various MX bike shootouts, the Hondas had the best brakes and Kawasaki the worst. Get CR caliper.
