Front caliper swap. Magura? CR? TRX?
Verde Grande:
Thanks for the info, gentlemen! Byron, you are a wealth of information; thanks!!!
Still, the garage tinkering hack engineer in me still wants to explore the 4-piston set up.
More cowbell!!! :-D :-D
Verde Grande:
Well, I came across an '01 CR-250 master cylinder and hose for only $20.00 so
that will go on first. I'd still like to explore the four piston caliper but for only
$20.00, this first upgrade is a smoking deal, no? Win!

I'm new here and yes, I did a search but didn't see my particular question addressed.
I'd like to improve the front brake on my '98 KX-500. Yes, I know about the CR lever, shorter hose, etc but what I'd really
like to do is mount a serious caliper and follow that up with the needed master cylinder. My first choice would be to mount a 4 piston caliper. Has anyone tried the Magura kit? Or has anyone been able to mount another type of four piston caliper?
The next option would be a better two piston caliper. Is there a CR model that is a straight bolt-on? Or do brackets need to be fabricated? Has anyone had any luck with a TRX caliper? (I only ask about the TRX because I saw someone talk about using the TRX master cylinder and was wondering if the caliper would work, as well.
Thanks!
edited to add: This is going to be for MX/off road use so I want to keep the stock rotor and wheel.

The 4 piston calipers just barely clear on the smaller 17in wheel due to the greater angle on the spokes and the larger 320mm rotor. The TRX master will only work with 4 piston calipers, since it is designed to push 2 - two piston calipers on the quad. The TRX master and a 4pad 4piston Brembo radial caliper is my favorite supermoto setup, since it retains the feel of a good dirt front brake rather than a big levered road master.
The 2009+ CRF450R master is a newer and better design then the other Nissan masters out. A larger 260mm rotor, short CR style hose, and CRF OEM brake pads will give you very good braking. Much more front brake than that and you have to much brake for the front knobby to control. I have tried a 280mm, and feel that they lock up to easy offroad.

Thanks for the info, PowerFiend!

what does a bigger rotor do :? :? :?
