KOSO RX2N

Got an unused, never installed Koso. I was troubleshooting a different one I actually installed and feared mine was defective which ended up not being the case so my loss it your gain.

Only thing different from a new one is the speedo wire was cut during the troubleshooting process but if you are soldering your connections it shouldn't be a big deal for you. It also has 2 miles on it but the factory protective thingy is still on the gauge.

Asking $200 plus a few bucks for shipping depending on where you live.

All yer Koso info is here:

If it was in the budget, I would be all over this. Unfortunately a deck is the expense of the summer.

It was not too bad. My bike is an 03, so it uses the old harness. The "hardest" part is getting mounted cleanly because the gauge no longer uses the mounts on the headlight ears. I ended up cutting and bending some steel strips in the stock location on the triple and it worked out well. Specific to wiring, here is a modified list that I posted on the big Koso thread with wiring directions. Just make sure that you solder and use shrink tubing.

This was copied from arctic954 wiring a KOSO RX2N gauge to his 919, the title of the thread was "Koso RX2N Finally installed" and a modification was added from the thread titled “Gauge cluster Wiring Digram for 2007 919” to add 12v constant from the harness and 12v switched from the harness. After a couple hours of digging, I found the nugget of goodness that allowed constant and switched to come off the harness and I wanted to have one central place with wiring info.

By following this wiring guide, I was able to get Neutral, turn indicators, high beam, oil, CEL, and temp to work on my 2003 using all harness connections, making the unit plug and play with my 2003. I am using the Koso speed sensor. Contributors, among many, are arctic954, bpolunin, ganktor.

Hope this helps, use at your own risk, I am not responsible for any damage
