Welcome to our all new Annitori QS PRO Quickshifter, one of the finest and most capable quickshifters ever offered. There are a huge number of changes as compared to the old version shifter, and we truly believe you will like what we have done for the new QS PRO 2…!

* 100% strain gage based

Like the shifters used by the top MotoGP and World Superbike teams, the Annitori QS PRO is a strain gage based shifter – the highest technology possible and without all the problems of old style mechanical based switches

* 100% Plug-n-Play installation

No cutting, no hacking, no splicing. Every connection is designed for your machine and for your ease of installation

* The QS PRO is 100% digital for unmatched reliability

Using our proprietary algorithm’s and sophisticated software to give you the most complete quickshifter available

* Fully adjustable kill time

The QS PRO kill time is fully adjustable so you can tune the kill signal to be exactly as you need! You asked for it, and we did it!

* Fully adjustable sensitivity

The QS PRO has fully adjustable sensitivity so you can tune the QS PRO to exactly what your machine needs! Again, you asked for this, and now you have it!

* PUSH, PULL and BOTH directional shift settings

The new QS PRO can be set for PUSH, or for PULL, or for BOTH shift directions. No need to be stuck with any “one” choice, and no need to have problems associated with not being able to turn off the unused direction. You choose, you decide. More then anything else compared to our old product, you wanted this and we made it happen! Then we go one step further…

* Individual directional settings

Our competitors might give you the ability to change a setting, but then you are stuck with that setting for BOTH your shift directions. With the Annitori QS PRO you can set you sensitivity and kill time specifically to PUSH, and then have completely DIFFERENT settings for the PULL shift direction – or vice-versa. You choose how to set up your QS PRO exactly how you want it, exactly as your machine wants it.

* The Vault

With the QS PRO you have the ability for you to store your settings, so you can quickly and easily retrieve them for different tracks, different bikes, or just different riding situations. Again, you choose now because with the QS PRO you control how you want to use your shifter!

* All NEW electronics

The QS PRO is not an update, not a software addition. The Annitori QS PRO is a completely new design that uses the absolute finest electronics with increased capability and vastly improved reliability to both protect the controller and eliminate issues found in previous designs. This is not in any way a “redesign” of our old product, this is a unique controller with specific changes that make the QS PRO as bulletproof as our engineers could create. The QS PRO controller is a seriously robust and quantitative leap forward because now that this is an Annitori design, so that we are now able to stand behind our product as our customers expect! There is no question the new QS PRO delivers!

* 100% Stand Alone design

The QS PRO does not need any other product to work, the QS PRO is 100% self-contained and 100% independent. So no problems with interface, communication or interference. Your bike can be a World Superbike with every option on the planet, or a bone stock bike – the QS PRO attaches and works exactly the same without any other products needed.

* ALL NEW smartphone NFC setup procedure

We are using the newest in electronic communication, the Android / Apple / Windows based NFC (Near Field Communication) to allow our customers the fastest, simplest and quickest route to making changes to any of the settings. Being able to use your smartphone to make changes whenever you wish eliminates the “old school” problem of having to be attached to your laptop or desktop computer. Right from the smartphone in your pocket you can do ANYTHING you wish with your settings – anytime you wish! (If you are unsure if your phone has NFC capability please contact us for information and assistance – happy to help you!)

* Completely sealed and weatherproof

No LED’s to burn out, no buttons to fail, no openings or external add-ons to possibly compromise the shifter over time. You all have asked for durable, the Annitori QS PRO gives you that and more!!
A Quickshifter is an electronic device used by virtually every high performance rider that attaches to your motorcycle and allows for clutchless upshifting.Normally on a motorcycle you roll off the throttle, pull in the clutch, move the shift lever to the next gear; then release the clutch while reapplying throttle.  This is how shifting has been done for 100+ years on motorcycles.  All of this takes time, and also has the very negative effect of causing the motorcycle to change chassis attitude as the weight of the machine shifts back and forth during the shift.A well designed Quickshifter allows the rider to stay on the throttle and without engaging the clutch, execute a virtually instant and incredibly smooth upshift to the next gear.  The RL does this electronically by momentarily releasing the torque on the gearbox while the rider is moving the shift lever, thus allowing the gear to be changed very quickly, smoothly and with minimal effect on chassis position or attitude.  It’s the closest thing to a “paddle shift” you will find on a motorcycle!



The Annitori QS PRO Quickshifter is an extremely sophisticated, fully digital and microprocessor controlled, Strain Gage sensor based system that is the highest technology available in the World today. Strain Gauge based shifters are used by virtually ALL of the top racing teams in the World, from MotoGP to World Superbike; and now Quickshifters are becoming stock parts on the highest performance bikes you see on your showroom floor. Without a doubt, a Quickshifter has become one of the most important products to add to any performance machine.

The problem has been that Strain Gauge based shifters were VERY expensive designs, with very complex and sophisticated software required to have them operate effectively.

Much too expensive for anyone outside of Factory backed riders.

Until now.

Our engineering teams have solved this complexity and created some of the most sophisticated software ever designed for motorcycles, and by doing so have created one of the most reliable, smoothest and quickest shifters available to the public.



Quickshifters are a wonderful addition to any performance machine. So much so that now the BMW S1000RR, one of the TOP performance bikes in the World, one of the most expensive performance bikes out there, comes with a Quickshifter straight from BMW. Why?

Because Quickshifters ARE a very useful and beneficial addition to riding. All riding, all the time, anytime you are looking for added performance to your situation.


“I don’t know why I didn’t buy one of these a looooong time ago. I can say I will never own another bike without one though… and hell, I haven’t even gotten to play with it where I normally ride!”             Kevin, GA – USA


Better acceleration, better handling, smoother lines, more time to focus on other parts of the riding situation. For the price of a rear tire you gain more performance then virtually any other addition you could add to your machine.

And the QS PRO adds that performance every time you shift.  For your favorite day at the dragstrip a good Quickshifter can shave a couple of tenth’s off any riders times, and do it EVERY time you go down the track.  To a Roadracer or track day rider, these tenth’s of a second on EACH and EVERY run through the gearbox translates to saving seconds on every lap, and that is not counting the time savings of using the Quickshifter correctly in long corners where you need to shift but never could before.

BMW (and we are sure many others in the next few years!) has the Quickshifter on their top performance machine for a reason; a Quickshifter adds every moment to the performance and ease of any motorcycle’s fun.



Your clutch is still there, and still very useful when you are not in a “performance” riding mode.  Using a Quickshifter to shift from 2nd to 3rd at 1800 rpm’s on a modern, 15,000+ rpm 600cc sportbike is not exactly going to convince you as a rider of why you spent the money. Not that you can’t do it, but honestly, you don’t need to spend the money when pulling in the clutch to “short shift” works just fine in that situation.

But we suggest you should not expect a huge benefit from any performance product in those types of situations?

It would be like putting $500 sticky “best ever” tires on your bike to then ride from NY to San Francisco, never leaving straight up and down on I-80.  Great tires, but not exactly being used for what they were made for.

Let’s use another example that might help explain: steering dampers. All of you have one, some of you went out and paid more then a Quickshifter to upgrade the stock one. But we seriously doubt you did so, or set your damper up, to “maximize” its capabilities at 6 mph…?

That does not make the product “bad”, it just means the rider is not at that moment using the machine and the product in the manner they were designed/purchased to be used in.

Quick rule of thumb? If you are on the cams; on the power, then Quickshifters are wonderful additions to riding. But that does not mean “redline” or “racing”. It means you are accelerating and the gearbox has torque on it. The more the better!

On a CBR1000RR that is earlier in the rpm’s then the more “peaky” 600cc power curves; just a fact of life and engine size. We don’t think anyone is having their arms torn out at 4000rpm’s on a 600cc sportbike? But most of you did not buy 600cc sportbikes to “short shift” (we hope!), so there are an awful lot of opportunities on every ride to benefit from the QS PRO.

Quickshifters are a FANTASTIC addition to any performance machine, when you are using the “performance” side of the equation. If not, a Quickshifter does nothing wrong and simply waits there for you to need its services again…

In the end, what we are trying to say is that a Quickshifter is a performance product, to be used on a performance machine, in performance situations. That does not mean race “only”, because there is little difference between running through the gearbox to merge into traffic vs. running the high banks at Daytona; or needing the next gear during a long sweeping corner on your favorite backroad as compared to the carousel at Road America …

Like the stock BMW S1000RR, it means anytime you are looking for better performance, no matter where you are riding.

    The Annitori QS Pro 2 was pretty easy to install. I measured my pre-existing shift rod length between the heim joints and used a short rod and longer rod to keep the sensor fwd of my rearset bracket.
    It took a bit for my Pixel 6 to connect, by my Android tablet worked the first time.
    As stated by Norton, the stock settings in GP shift configuration were great. I tested the setup at Thunderhill West (2-mile track) where there is a lot of shifting on the tight course. Being able to just step for a gear while WOT was a great feeling.
