Hi Jack,
list price is $139.99.
The initial most noticable difference is stiffer damping which can be fully
varied, like cartridge forks, so you can set them up as you wish. I have
mailed a response to you question to the group too.
Off /on road, the tendancy for the front to wash out has been eliminated, a
combination of springs, damping and fork oil. That gets into suspension
tuning.
For me, my confidence in not loosing the front went up 100% or more. It no
longer feels vague, but taught. For mostly street riding a softer setting,
around 2 turns on the valve preload will give a softer, but still taught
feeling. You can set the valve preload between 0 and 7 turns (probably feel
like a street race bike and brake your wrists

. Another noticable
difference was much less dive under braking, which reduces weight transfer
and improves rear brake eficiency, Its very easy to lock up MT21's on the
street anyway, but with street tires you will have a great rear brake (DP MX
pro pads). I noticed on improvement in front braking too, again with MT 21's
its easy to lock the front, but braking feel (handling, control under braking
has improved).
Well, I like them. The front end feels NONE KLR, great.
Regards,
Brian
