Is there any way to calibrate my speedo on my 2011 limited ? It's about 4 off and drives me nuts.

 

Just like every other Harley speedo ....

 

Some of the ECM tuners will allow you to do that. Power Vision for one I believe, I have one but haven't tried that function. My speedo reads exactly 3 mph faster than the gps and that may have saved me a ticket or two.

 

As has been said, some of the tuners will do that. I have a Power Vision and part of the dyno service I had done was to calibrate the speedo. Expensive if you're not going to use a tuner anyway, but something to keep in mind if you do decide on one. Be sure to get one that will fix the speedo.

My Street Glide is off to based on those electronic school zone speed limit signs that flash your speed (in a stern bright red if you're speeding)....Pisses me off. Why can't HD just properly calibrate IMPORTANT instruments on the $23,000 machines they're selling people. I love my bike, but some of the BS shortcuts and laziness the MoCo pulls is really infuriating.

 

It's not just HD. As far as I know most of the metric bikes are the same way. I know my Honda VTX 1800 was. I'd bet that there was a legal reason. It's too wide spread among the manufacturers and too easily fixed. I've been told that the Rushmore bikes do NOT have a speedo feature on the built in GPS. Harley doesn't want you to know how far off the speedo is. According to my Garmin, my Ultra was 4mph off. Fixed it with the PV tuner.

I use a "Speedo Tuner" it plugs into the speed sensor about $80 on evilbay. Baker makes a plug in calibrator too.

 

I bought a HealTech Speedo Healer for my Yamaha FZ1 after making a sprocket change. It works great on that bike. For Harleys you need to know which ignition system your bike has. They are $116.99 through a vendor they link to on their site.

All vehicles are like this, its a liability thing. Better to say you are going faster than you are, than slower.

Many variables can affect this - wheel size, inflation, etc.

If you have a power vision, here's how you calibrate your speedo for free:

I run with a Power Vision and used it to adjust my speedo. I'm spot on with GPS now. Easy to do if you have one. I love mine.
