      Rated 5 out of 5 by from Every bit as great as my buddies told me it would be! I wasn't too sure about setting colors, but then I gave it a shot and I figured, why not have the dial (top part) set to RED, the tech (needle) set to WHITE, and the LCD (bottom) set to BLUE. Wow, I got a few positive compliments! :D

      Rated 5 out of 5 by from 4 in. Combo Digital Speedometer/Analog Tachometer As a computer tech, Internet lineman, System Analyst, System Administrator and programmer with a masters degree, I prefer digital computer functions over analog functions. This system has more digital functions than the default.

      Rated 5 out of 5 by from Lots of info It is so nice to have a gas gauge, see the gear I am in, my rpm and speed all at the same time on such a nicely coloured display. Being able to check my miles till empty is nice too. A nice upgrade from the stock unit.

      Rated 5 out of 5 by from Pretty nice upgrade over the stock If I had known you could see your rev's and gear position on the stock gauge I never would have ordered this one. That being said, I'm so glad that I didn't know that because this speedo/tach is so nice and easy to read. It is so nice being able to see all the information at once. The optional fuel sensor is nice even though the stock one still has a low fuel warning. My only complaint is that the digital readout is so nice that I'm now disappointed when I drive my car because it doesn't have one.

      Are there any Plans to make this available in a 5" model for a 2012 fat boy?

      P/N 70900100C & fuel sensor

      Good day, I have a non US 2014 Forty-Eight, is this the right part (4 in Combo Digital Speedometer/Analog Tachometer P/N 70900100C) for my bike? And if I install it without the fuel sensor kit, would it still signal the low fuel light as the original one does? Also, I cannot find in your page the fuel sensor for this tach for non US models. Many thanks!

      Is there anyway I can install this on a 1997 Sportster 1200?

      I really like the look of this piece and I'd like to put it on my 1997 sportster 1200. I'm not worried about the fuel level indicator or the gear indicator, but can I still use this for the speedometer, odometer, and tachometer?
      Asked by: Alex717
      Hey Alex717, Unfortunately, this Speedo/Tach combo isn't validated to fit a '97 XL1200, and we can't make any recommendations on fitment that's outside of what's been tested and validated by our P&A and Engineering teams. Thanks! Rockstar883

      Will this unit be a simple plug and play for a 2016 FXSB ?

      Asked by: ajetna
      Hi Ajetna, Well, the installation of the 4in. Combo Digital does include a little more than plug & play. You will have to make all the necessary adjustments for this part to work correctly. Please see full I-Sheet on H-D Online Store. Thanks!

      Fuel level Sensor incorrect reading

      2016 Iron 883xl Speedo/fuel level sensor kit installed. Will not read proper level of fuel, approx. half level on empty tank. Rode 3 full tanks already, still won't calibrate.
      Asked by: SParkerx7
      Hey SParkerx7! This part is for Non-US models only. An additional P/N 61200008 is needed for the fuel level and range to function properly. If you have an U.S model, please see part (70900475). To configure this part you will need P/N 61200008A. Contact your local dealer if part will not configure correctly.
