Mine is more or less 10 mph off (too slow) up until 55 or 60, so I just add 10 to whatever I see on the speedo. I recall from other sites that some people do what Mrscoot says (find out where the real speeds are) and then make a new speedo face from an on-line template, like this: forums.vwvortex.com/showthread.php?4838553-Template-for-speedometer-anyoneif you google "speedometer template" you'll see dozens of choices. |

I lie the bicycle computer idea. If they are setup right they are very accurate.

My majesty is correct up to 60mph then it goes off by a hot 5mph

Most chinese scoots I ran across may have mph on speedo face but are set to kph. Even some that are labeled kph are still off... but we keep buying the crap anyway.  |

Despite all the other issues with my 2007 Lance Vintage the speedometer was spot on 100% accurate. Matched GPS and measured mile calculations.

Re-marking the speedo face is a good fix! If you can get the speedo lens and needle off, you could even make a new face on your computer, print it on good paper and laminate it, or simply spray it with several coats of clear lacquer and glue it over the original. You COULD try fitting a larger-diameter front tire, which would be OK if it fits under the fender, but a new speedo face is probably the best option. If the speedo face is NOT readily accessible, marking the lens at common speeds is a good alternative. You could do it with sign-makers vinyl, or model airplane "Mono-Kote" or similar product which will hold up for a good time in outdoor use. I'm with you, in that I'd like an ACCURATE speedo. No factory "fudge-factor" to keep me legal, thank you... Incredibly, my 2007 Xingyue 150 speedo AND tach were dead-accurate! I'm now riding a 2007 Kymco 250 and the speedo is 5-7 mph "optimistic"... It's a digital speedo, so there's not much I can do, so I just subtract 5 mph from the reading... Local traffic routinely runs 20 to 35 mph OVER posted limits... So I'm used to my speedo showing 55 to 70 in a posted 35 limit. The old Kymco WILL do an HONEST  , with the speedo reading 91-  but THAT is absolute WOT and not suitable to cruise at. Like others have said, most scooters and bikes have wildly optimistic speedos... It's just the way they are. Ride safe, Leo in Texas |

Yup a bike with a pestimistic speedometer... It could be due to quite a few factors. Speedo puck from the wrong year bike is my guess, or it could be just gummed up too. It is an '82 afterall. My point being, it's always good to GPS a speedo to see what you got. I found out, for example the wing is doing about 73mph at 65 indicated. The Aprillia, is pretty close, about 3mph off at 65 (optimistic)... the 250 I own, just always says 0mph... (bad speedo puck) but when it worked, it was really optimistic... say like 85mph at 50. It lies I tell you, it lies..... Anymore, I just stay with traffic. It's just better that way! What do I have to prove, the Aprilia and the wing, will both do the ton, or so close to it that it won't matter until you a street pizza on the pavement. |

I read a write up not long ago " I posted it on one of my threads " not sure which one . But someone opened the speedo and adjusted some needle or something and It fixed the problem . It wasn't the speedo needle on the gauge it was something inside .

Some speedometers use a clock mechanism that can be adjusted while some of the electronic ones may have a pot that can be adjusted however the newer ones are reading a magnet or optical wheel passing by a sensor and are programmed to a particular wheel size and that's it unless you get a device that reads the pulses and lets you adjust its output to send the correct data to the speedometer.

Urbanmadness may have the BEST answer: Just ride with traffic! Duh... Simple but effective!
Thinking back, my first rides (Harley chopper and BSA Hornet 650) did NOT have speedos at all... I just rode with the traffic... 25 or 125... LOL!
My first bike with a speedometer was a new 1967 Honda 305cc "Super-Hawk". THAT speedo was spot-on. Some of my later bikes had speedometers, some did not. "Back in the day" they were sorta "optional"... But were usually accurate if your ride had one at all.
With TODAY'S riding bouncing around from EXTREME over-the-limit speeding to run with traffic, and occasional EXTREME no-tolerance enforcement, an accurate speedometer WOULD be nice... But not always possible.
Ya just gotta do your best...

Here's what I did to fix the speedometer. Tore out the guts, gutted a 17-euro Sigma, cut a hole in the speedo face and attached the sensor to the fork and a magnet to the brake disk.   |

, with the speedo reading 91-
but THAT is absolute WOT and not suitable to cruise at.
