May 2015  Review:

Very sound product.  Put the stacks in my 2014 gsxr 750 - Wwhat a difference it made. Goes great with a full exhaust system and a power commander V. Easy to Install - takes less than 1/2 hour.
You will notice the difference right away - better throttle response and you can tell the horsepower gains.
With everything else, the stacks are the icing on the cake.

It's a must have!

Pro Shift Kit

RM-z250  07-14 (and RM-z450)

Virtually eliminate False neutrals and missed shifts.

Factory Pro has delivered quicker shifts and helped save thousands of gearboxes from damage caused by missed shifts. New in-house spring design capabilities now allow us to produce more custom spring applications.

This F-Pro Competition spring helps the RM-z250 shift quicker and miss fewer shifts.  Use the new microbearing arm and comp spring for best shifting

    Works great!  It was easy to install.    Mike Berger, Ohio, USA  July 2013
    "Works well - the shifting feels different. I didn't miss any more shifts."  Lance H.  Petaluma, CA    July 2013
     It's freggin awesome. Night and day difference.. I raced this weekend.. 4 motos and never a missed shift or false neutral  Dec 2013
  I had the new detent spring installed and also went with the Factory Pro arm - it doesn't have any slop/play like the stock unit does. Rode it today for the first time and it shifts like my 450 now. Not a single missed shift. That's the best spent mod I may have ever done,    Dec 2013

Note from Marc:
The "Midrange" Race stacks are my choice for any street and most track use.

The additional 4-5 HP across the 7000 to 9000 rpm range augments the 2 True HP gain at 10,000 rpm.
