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!

     "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

zx10r Shift Springs - New as of July 2013

For even quicker shifting before or after our Shift Stars - install one of these inexpensive springs.
These are a different rate and heat treat than stock - and the icing on the cake - they enable even air shifters and quick shifters to shift quicker. How simple and direct could it be? Used in drag, road and land speed racing.

"Aiming for that 30ms shift."

Pro Shift Kits for Ducati

Face it, under hard use, Ducs don't shift with a "snick" or with a sense of urgency. Kind of lazy, actually - unless you split the cases and spend hours polishing and radiusing "the stuffini" inside.

This simple kit installs in 1-2 hours and removes significant shift drum friction and helps Ducs shift smoother and quicker - street or track - Miss fewer shifts.
F
ind neutral easier.
Sure beats the old "take out the neutral detent in Ducatis" racing trick.
