dude that SX-r is an awesome sled.
sure its not the fastest but the suspension is great if set up properly. it corners flatter then just about anything out there...and it rides pretty good sled or fast.
i had a 98 zr 600 last and this sled is 10x better.
MXz's are ok but i dont think there half the sled the SXr is.
reliability is awesome, they feel so light in my opinion, fit and finish is top notch, controls are awesome, gauges nice, awesome looking sled...etc
the regular sx's dont have half the suspension the SX-r's did.
you cant go wrong with a yammie.
check out my site for more info on the SX-r line.
