These are supposed to be better than the oem slotted or aftermarket drilled rotors in mud.

Howcome? Seems any 'cleaning' action of an edge, whether it be hole or slot would be a good thing...in the mud, in the water or anywhere else.

Who has used both and has an opinion either way?

Thanks.

I've not used solids, but I won't let that stand in the way of expressing my opinion anyway!!!

I too have understood that the holes or slots will help wipe the pads clean and also help in drying when wet. I've also heard that the pads will wear faster as they are subjected to the edge of each opening. As for the stock KDX rotors, mine allow too much braking as it is, and I make some cut marks in my pads to minimize the brake surface. Maybe that's how solids aid braking; the pad is in contact with more rotor for a given range or travel and can slow you down quicker. Just my guess.

On this note: I've heard the wave rotors are better than stock. Any guess as to why? (No hyjack intended)

The wave rotors are the best of both worlds... They are solid without slots and they clean better due to the wave design. Another advantage of the wave rotors is that they don't overheat as bad because the rotor is never in the same place on the pads for long. These are on my list..... DAMN LIST!

You can get a set for a little over $200, not bad!

If you buy Wave rotors... try to find the Galfer brand rotors. They make rotors for MSR which jacks the price up for the same rotors. Galfer is about $115 and MSR is about $139. Also, they don't list them specifically for a KDX rear...but you can cross reference the rotors because KLX 300 uses the same rotors. Why they don't do this... I will never know.

The solid rotors for mud work because of more surface area and they are stainless. Which they say grip the pads much better. On a side note, the solid rotors are much tougher than standard rotors and there is not much need for a disk guard.

I think the slots pack with mud, then allow a little to pass onto the rotor surface so the surface gets a good grinding with the grit.

I have never used them.
