QS linkage sensor small photo sensorimagesm_zps923b8063.jpg  


The Annitori QS PRO Quickshifter operates from a signal created by our exclusive Strain Gauge sensor which is attached to your shift rod.


The sensor in our kit is 50mm long, so to attach the sensor and still maintain the correct shift rod length for your motorcycle you need to have a shift rod which is 50mm shorter than the one you have now.

 

WHY DO I NEED A NEW SHIFT ROD?


The reason we make the purchase of the shift separate from the Controller is that many riders and racers have a toolbox full of shift rods, so they don’t need a new one from us. Or, many riders have aftermarket rearsets on their machines, and each of these brands has their own length of shift rod depending on the design and thus need different lengths then the stock motorcycle.
So although we have quite a list of known shift rod lengths for the OEM (stock) setups, there is virtually an unlimited number of possibilities from all the other options out there; and those setups need to use the guide below to help determine the current length of shift rod so the new shift rod length can be purchased.
If you motorcycle footrest is all stock, then please click on our STORE link and the shift rod length needed should be listed there. If not, then please use the information below to determine the shift rod you need.
As always, if you need assistance or just want to be sure, please feel free to email us at info@annitori.com and we will be happy to sort this with you. Be sure to include the exact make, model and year of machine you have, and attach a few photo’s of the shifter setup with a measuring device below the shift rod (as in our example below) so we can see what you are looking at and what length we are needing to discuss.
This is not a difficult task, just takes a few minutes and you can be on your way to the best upgrade you have ever made to your motorcycle!

 

SHIFT ROD MEASUREMENT GUIDE




To install the QS PRO Quickshifter on your machine you need to attach the Strain Gauge sensor to your shift rod. The reason we make the shift rod a separate purchase is because many riders have a toolbox full of old shift rods, and can source their own.
For everyone else who needs a new shift rod, here is a guide to determining what shift rod length to purchase with your Annitori QS PRO Quickshifter.
The RL Sensor is 50mm long, which means you need a new shift rod which is 50mm shorter than the one you have now so the overall length will be normal again after you install the sensor.
For example: if your current shift rod is 215mm, you subtract the QS PRO Sensor of 50mm and this means you need a 165mm shift rod from us. 165mm + 50mm = 215mm, the correct length again.

 

MOST MODERN OEM SHIFT RODS

Virtually all of “stock” modern sportbikes use a solid body shift rod, double female ends where the rose joints screw into the shift rod.

From the above:
RED = The “body” of the shift rod, not threaded
BLUE = The extra thread length for adjustment, left and right
These are very easy to work with, simply measure the length of the RED section, subtract 50mm and that is the length of shift rod you need to purchase from us.

 

MANY OEM SHIFT RODS WITH THREADED ENDS
(mostly older bikes)

Here is a photo of a shift rod with normal length threaded “male” ends. This style of shift rod mostly uses female rose joints which screw onto the threaded shift rod. For many of these applications you will need to make sure you have a left hand (also called reverse thread) grub screw for installation of the QS PRO shifter.

From the above:
RED = The “body” of the shift rod, not threaded
BLUE = The extra thread length for adjustment, left and right
GREEN = The amount of thread needed to attach lock nuts and joints at each end, left and right
Do not “over think” this; it is not algebra or calculus. With your shift rod installed as you like it, there should be approximately
5mm of extra thread at each end, like the photo above, for adjustment.
VERY IMPORTANT NOTE: If the threaded portion of your shift rod is longer than this, consider using the next section for shift rod measurement. If you are unsure, email us photo’s of your setup and we will help you sort this.
Now simply measure the RED length, subtract 50mm for the QS PRO Sensor, and this is the length of shift rod you need to order from us. For example: If your shift rod “body” is 165mm long, then you need a 115mm shift rod from us.

 

OTHER SHIFT RODS WITH LONG THREADED SECTIONS

Here is where the measurement gets to be a little bit more involved. But DO NOT PANIC, it is just a bit of “thinking” and then addition and subtraction!
Many aftermarket rearsets (and some OEM) shift rods use a very short “body” length, and very long thread lengths. See the example below:

From the above:
RED = The “body” of the shift rod, not threaded
DARK BLUE = The extra thread length for adjustment, left and right, just like the OEM version. It is normal to have approximately 5mm at each end for adjustment.
GREEN = The amount of thread needed to attach lock nuts and joints at each end, left and right, just like the OEM version. This length will be determined by your particular setup.
YELLOW = The “extra” length that is the body, but is threaded in this version.
LIGHT BLUE = The actual “body” length of the shift rod to use for measuring and subtracting 50mm out of for the QS PRO Sensor.
Comparing the images from above, you can see in this example that the body length “RED” is not nearly the full length of the shift rod. The “threaded” portion is extra long and is now part of the “body” for our calculation.
Again, do not “over think” this; it is not calculus. Make sure your shift rod is installed as you like it, then measure the LIGHT BLUE length, being sure you have allowed for approximately 5mm of extra adjustment thread on each end in additiion to the thread you need for lock nuts and ends. This is the length of your shift rod. Subtract 50mm for the QS PRO Sensor and this number is the length of the new shift rod you need to purchase from us.

In the end, if you have ANY questions or are unsure, simply email us some photo’s of your shift rod setup to info@Annitori.com and we will help sort your questions quickly with you.
