So I've heard that cops give bikes a little bit more leeway on speed because the speedometers are sometimes off and harder (if not impossible) to properly calibrate. (don't know if it's true, don't care. I am just saying what I heard. Don't flame me for that comment.)

I do know that I was riding the other day and went past one of those "This is your speed" speed traps, and the blinking light said my speed was 41 (I was in a 45 zone)....But my speedometer said I was doing 49. So I figure my gauge is about 8 miles off. My brother has a GSX-R 750 and his speedometer is off too, but he said something about a "speedo-healer" or some other gadget. (never heard of it before.) Is there a way to re-calibrate my speedometer, or am I pretty much out of luck? If it is possible to re-calibrate it, does anyone near me know how, and would be willing to do it?

Thanks for your help.

It's not a set mph that it is off, it's a percentage. The faster you go, the more incorrect.
Buy a speedoDRD.
Inexpensive, easy to install and calibrate and works flawlessly.

Be aware that many modern motorcycle speedometers are off by as much as 10% (the manufacturers build 'em that way,) but the odometers are pretty accurate.
So if you use a speedometer-correction device (such as the speedoDRD,) your odometer will now be off by the amount of correction you dialed in to the speedometer.

This could work in your favor, as the odometer will now typically read fewer miles than actually ridden.

I refer to those Radar speed signs as "high score wins!" signs........

Hmmm. I didn't know that. Is this true as well with digital indicators? Good to know!

Same with cars. Mitsubishi is one of the worst offenders.

Really screws with MPG calculations!

I have a speedo healer and it works great. My bike was off by 19% due to after market gearing. You just use a GPS to get correct speed at around 60 mph then calculate a percentage difference to what your speedometer says and input to speedo healer. My speedometer is dead on at 60 mph and only off by a mile at 30 mph. Not sure what is happening at 145 but at that point who cares.

 

[inod3]

My bike is off by about 10%. With speedohealers you have to decide, do you want accurate odometer readings or accurate speed readings? I can't see myself spending the money when I'm still going to have something inaccurate, so I just figure my speed - 10% = real speed. You adjust fairly quick, perhaps if I had multiple bikes with varying differences in the speedometer readings it could get more confusing.

Now, if I could get both accurate odometer readings AND accurate speedometer readings that'd be perfect. Seems stupid as fuck that motorcycles have intentionally inaccurate speedometers. (I understand somewhere there's high penalties on manufacturers if a bike speedometer reads less than the speed so they all just make them read too fast. OK, fine. The manufacturer should give me a way to adjust it back to normal.)

Maybe this could help?

Both my Kawasakis were off 8.8%, Speedohealer and then GPS verified. I want to know exactly fast/slow I am going. I care less about the ODO.

Mine was off that % accross the board.

PS: In packwood during the SCCA events, police say they will ticket anyone 3mph over. Thats why I don't want to do mental calculations on my speed, I want it exact!

LEO's are real picky in school zones too.

cheers.

Not mine, my SpeedoDRD corrected both my speed and odometer!? I checked with GPS and against mile markers, both are very close now. :secret:

I've just installed the Speedohealer in my 09Fz1. Was off 5 mph to the slow. I have heard the other has issues, just an FYI. None the less you'll need a good GPS on the bars to set it. I like the high score..

I play that game too. Most of them around my house don't detect bikes though

I'm so glad you guys are talking about this and sharing your stories. :mfclap: Wow can't believe dude's was off by 19%!!! I think I've heard of a few others that high, but not often. I heard about this and the speedohealer for about 3 years now and people just don't believe me. Even had one person say that they did see those street radar things showing a different speed than their speedometer and though the radar was off.

+1 My bike is off my 10%, checked it against my phone's GPS, and that's across the board at various speeds. Sucks that when I did a buck 10 on my '87 Honda Shadow 750 that it was slower than that. Bummer.

+1 I just do the calculations in my head. I've got a good legal services to fight those tickets is I get caught going 3 over or so. Egads!

+1 Checked my car too and I'm off by a couple of MPH. Grrrr.

So before my group rides I warn people about that and tell them I go by GPS speed especialy for rides I lead for novice riders. Went okay on my last one. We'll see how it goes on the next. (Feel llike the boa Kaa in the Jungle Book singing "Trust in Me") :ROTFLMAO: Trust in Me

Where did you hear that and what issues?

Fz1 forum, may be just an FZ thingy IDONO. Took them dudes a long time to get it to stop but it did. Google it, it should pop up.

Here's a link to the speedohealer I heard about. Still there after 3 years:

I'll stick with my first hand experience I think.
