Hi All,
Recently I was selected by 12'oclock Labs ( http://www.12oclocklabs.com/ ) to road test the new plug and play speedo healer. If you have ever swapped out your stock sprockets you are aware that by changing the amount of teeth on your spockets throws off your speedometer reading. This speedo healer is this first plug n play calibrator for the 2007-2010 CBR600RR (all other calibrators require wire splicing)
Anyhow I figured I would do a write up on the simplicity of installing of the speedoDRD. I am by no means the most mechanically inclined person and this is my first DIY write so please bear with me and feel free to contribute.



The speed sensor is located above the transmission and below the gas tank. The easiest way to access the sensor is by removing the tank fairing, and tank bolts



Once the tank fairing has been removed located the speed sensor wire harness located above the transmission. (the speed sensor harness has violet, green, and pink wires on one side and red,
back, white and green on the other)



After locateing the wiring harness disconnect it and connect the speedoDRD directly to the male and female ends of the speed sensor.




once you have it connected you can either run it out the side near the shift rod



or route it up above your airbox



i choose to route it above the airbox. reason being is that i was required to do a quick roadtest and verify that the maxspeed feature was working properly. in order to perform this test you have to be able to access the board rather easily after riding (it only save the maxspeed from your most recent ride). for the roadtest i used zip ties to mount the sensor slightly above the shift rod. above the transmission near the original speed sensor harness. after a quick five mile ride i tested the max speed feature and noticed that the board got extremely hot. a little worried i would melt the board i choose to reroute the board above the airbox. by doing this i will not be able to use the max speed feature unless i remove the tank fairing.

12 o'clock labs has a calculator on there website to determine your calibration factor. they use an equation based on your stock sprocket teeth and what you have changed them to. in my case my stock sprockets were 16, and 42. my aftermarket sprockets are 15, and 43. my cal factor is -10.4% using that cal factor programming the sensor took less than 5 minutes. got it right the first time and once the test is complete it verifies the cal factor. 12 o'clock labs also has a youtube vid on programming the sensor.

i am sure i forgot something, and will add it as needed. that is all for now thanks for reading my first DIY. i hope my broken grammer didnt give you a headache.

On most bikes you can. It's a good way to ensure you plug the speedoDRD into the correct harness. To unplug it and ensure the speedo isn't working and then you know you have the right harness. Not sure about the honda's, but on most all bikes you can ride w/ it unplugged.

so question.. can i unplug that speedo harness and run my bike w/o a speedo and w/o it gaining milage?

Woah! This looks awesome. Anyone getting just to correct the factor speed error? It would be nice to not feel like I'm speeding on the freeway when im at the speed limit.

Most don't get it to correct the factory error. I mean most cops won't pull you over for going 2% off. That means if you're speedo says 55 you're really doing 56 lol. Some bikes could be off a bit more, but still not enough to warrant a ticket. Most do it only when they change their gearing on a bike.

my speed reading is almost exact. i have tested it with a garmin, and when crusing at 60 mph the garmin reads 60-61mph.

Alright quick question. If you change your gear size, and it screws up your speed, it also messes up your correct mileage right? Will the speedo healer fix the mileage error? I havent done the change so i have no idea if its wrong... Or is mileage read from somewhere different?
