hey guys, i'm curious to know how far out your speedo is. it seems mine is about 10 kms out. 110km/h by my speedo is pretty close to 100km/h in a car. i haven't tested it with gps yet. but am curious to know if anyone has this problem.
Apparently those that ship to the U.S market have accurate speedometers, but for all other countries, the speedo is out by +10% which tallies with your experience.
I too would like to have my speedo accurately tested. When riding in some particular speed zone, I just read 10% over on the LED and think should be about right.
If misguided in doing this, I'll let you know if I get a ticket.
I reckon 10, 11% optimistic is about right. I sit on 110 indicated in a 100 zone, 120 in a 110 zone, and havent (touch wood) had any speeding fines yet. If i'm not on the highway, i just go with the flow though, pretty much regardless of speed
WRT a GPS like waze, the speedo is out like -10%..
But w.r.t other cars in my country we have the same Speed, so I guess all speedos are inaccurate in my place xD
I passed by a couple of those big speed signs that tell you how fast you are going and it was only about one off or my speedo was reading 25 and the sign was flashing between 23 and 24mph.
Mine is spot on and WAY more accurate than my Ninja250's.
I used to sweat going by known speed traps on my Ninja because I really had no idea what speed I was actually going.
You could chop off 5mph and still worry you were speeding, it was that inaccurate.
I feel a lot more confident on the CBR in the same situation.
I can not figure out why the speedo's on the bikes used in Australia and other countries that use km's are not accurate. I have checked my U.S. model with my gps in mph mode and the bike is spot on. Then switched both the gps and the speedo on the bike to kph and it is still spot on. It would be interesting to find out if the part # of the speedo is the same on an aussie bike to a yank bike.
Something to keep in mind, is that as your rear tire wears down the speedo will read a slightly higher speed than what your actual road speed is. The smaller diameter of a worn rear tire has to rotate more for a given distance, than a new tire (of the same brand, model, and size) would for the same distance. Thus, the worn tire will cause the speedo to read faster than the true road speed. A larger diameter tire than the OEM stock size would have the opposite effect... the speedo will read slower than the true road speed.
I purchased a SpeedoDRD speedo healer from 12 O'clock Labs online. Now my speedo readings matches my GPS perfectly. Others have stated on this forum that a speedo healer is apparently illegal in some countries. That may be true - and I don't know what the legislation reads in Canada - and personally - I don't give a flying f*&k. I want to know exactly how fast or slow I'm going at all times. I appreciate precision and accuracy. All of my three bikes now have speedo healers. This is the best single mod I've done to my CBR250R yet.
That seems so crazy that something which can correct an inaccurate speedo, would be considered illegal in certain countries. Maybe the lawmakers are concerned that, because it has to be programmed for each individual application, there is too high a probability for errors which would then lead to people driving well over (or under) the posted speed limits. Must be some sort of logic behind such a law.
