Excuse my bad english.
For 85cc MX 2-stroke bikes, Honda CRs and Yamaha YZs are the fastest in the top end, but the Kawasaki KX and Suzuki RMs are low - mid end monsters. KX and RMs have Powervalves which make smoother powerband for the bike, and make it more suitable for riding on different types of terrain such as trails, mountains, hills, etc, while the YZ and CR are mainly designed to be on the track for the most part.
If its something to mess around on for fun, a KX or an RM is the way to go. And luckily, both make 100cc models which more than make up for and kill the CR and YZ 85 in top end power, and also roar with low end power. RM and KX merge and make the same bikes for their RM/KX 60, 65, 85, and 100's.
My advice is to go with a kx or rm 100
