Universal KOSO GP-Style speedometer Type RX1N with white speedo face.



Dimensions 152x81x28mm. Has a very beatiful shape that compliments the lines of the scoot perfectly. The clearly designed instruments are easily to read even under hard acceleration. Here is a short list of the features:
  • Speed Unit reads km/h or MPH
  • Reading up to 360 km/h or 223 MPH
  • Odometer up to 99999,9 km or Miles
  • Two trip odometers up to 999,9 km or miles
  • Speed warning in the range from 30 to 180 km/h (20-110 MPH). Adjusting unit in 5 km/h or MPH
  • Memory of reached Top Speed (0-360 km/h or 0-223 MPH)
  • Rev Counter up to 15.000 U/min. Unit 100 U/min
  • Memory of highest revs
  • Temperature gauge in °C oder °F from 0-120°C or 32-248°F. Unit 0,1°C/F
  • Temperature gauge with bar chart from 20-120°C (68-248°F). Unit 10°
  • Digital Oil temperature reading from 0-120°C (32-248°F). Unit 0,1°C/F
  • Memory function of highest temperature
  • Fuel gauge with bar chart. 10 bars each 10 fuel level
  • Works with most common tank sensors. 100 Ohm or 510 Ohm
    Free setting of reserve warning between 10-50.
  • Clock
  • Acceleration Test 1, how long does it take to pass a given distance. Distance can be defined between 50-1000 m (1/32 - 20/32 Miles). Unit 50 m (1/32 Meile). Perfect to get used to sprint races
  • Acceleration Test 2, how long does it take to reach a selected speed. Speed selection is possible from 30-360 km/h (20-220 mph)
  • Top Speed Timer Testing, here you have info about your reached top speed, passed distance and max revs
How do you like it?

Yep, I have it installed on my bike...
Works great except of the fuel gauge.

I especially like that it shows oil and water temp :)
Ooooo...I'm interested to know as well. As I'm SERIOUSLY considering adding one of these.

What's the issue with the fuel gauge?
Here is a pic of mine:


The problem with the fuel gauge is that it "Works with most common tank sensors. 100 Ohm or 510 Ohm".

The SV uses some kind of two level switch that makes the fuellight flash or light up and that isn't compatible with the Koso speedometer.

Wow, it's so wee! I always thought they were bigger.
How did you mount yours?

I have to figure out how to mount it....

+1 on that.

Hi Luis,
the speedo comes with a bracket that is screwed to the back.
I built another bracket from an aluminum plate
and mounted it in the headlight.
How did you find the wiring project? I'm still in the middle of a big bout of indecision about the future of my bike but I'm looking at a similiar Koso as a possible gauge set... I'm OK with wiring but I'm no electrician ;)
Wiring seems easy...

Match cluster color wires to the SV650 color wires...

Splice the SV wiring harnes... No need to cut wires.

You mean you got a problem with connecting the Koso speedo to the right wires? Think I can help you with that...
Nah, I've not got one, just wondered how good the instructions for what wires do what is, etc. I fitted an older Koso to a mate's kit car a few years back and it was a godawful b*****d of a job, the instructions were all over the shop, very badly translated. But it sounds like they've upped their game a bit
I see. The instructions have been ok for me.
Haven't had any problems...
so... that means we loose all the fuel warning function installing KOSO?

isn t there a trick to fix it?
There is, with LEDs anyway, but it's a bit complicated... Worth looking for though, it's definately been done, but my link was for the old forum and it's gone.
Yep, there is a way to fix that with an equivalent circuit that replaces the circuit thats been lost with the stock speedo.
I have the Koso. I spent the extra money over the Vapor sets beause I really wanted the analog tachometer, and this one has excellent styling. Plus it's loaded with features, minus the fuel gauge (I just use my odometer).
I got a sweet deal on mine too... That is why I extra like it... ;D

$108.05 @ Cycle Gear... They have been awsome!!!

Luis
$108.05 is really sweet :eek:
I had to pay about $240 for this thing :(
I got mine from Blair at SV racing parts. He gives a discount (don't remember the exact amount)

It's a sweet setup. the only thing I haven't gotten wired is the temp sensor and the fuel gauge.
I also ended up running the speedo sensor to my back wheel cause it fit nicer.

nille, what did you do for the temp sensor?

TIA
