My speedomiter is off

For about $100, or change your sprockets (insert 17/39 joke here). Or do mental math like everyone else.
 
An elegant solution is to migrate the speedo cable from your front wheel to the rear (the circumference of the rear wheel being about the same percent larger than the front as the percent error in the speedo), but this is not possible on every bike.
 
If it bugs you that much (like it did me) these guys make a device called a speedohealer. It's about $100 but for me, it was worth it. Easy to install.

Having it read faster is fine. It saves you money in the long run. (you avoid tickets...and it gives you a good excuse when you do get pulled over when they ask you "Do you know how fast you were going?" "Yeah, about 10 mph less than my speedo said." It's the perfect way outta that one. :laughing)
 
Yeah, that the CHP's job!:shame

BTW, how do you know how fast you're going?

Funny thing lol a bunch of little towns on the coast up here have the you are going this fast signs set up on the road as you come into the town everytime I went past one it said I was going almost exactly 10 MPH slower then my bike
 
Most bikes have a built in percentage error that is pretty linear. For my bike, the speedo is off by 7.2% or there abouts. It's an error that is very easy to live with, but it annoyed the heck out of me!
 
My bike is 17% off. Apparetnly I cruise at 90mph on the freeway yet still have no tickets :teeth
 
After I put on a different set of tires on my ninja (Dunlop GT501, front 110/90/16 rear 130/90/16), the speedo matches pretty much the GPS speed.

(However, the front fender had to be raised for the bigger tire, simple mod. Dunno about the newer ninjas.)
 
Don't the EX 250 and 500 have the speedo sensor on the front wheel? If so then the sprockets shouldn't matter, and I'm not sure if the speedohealer will help.

The cheapest way to get this "fixed" would be to install a bicycle computer. A cheap one can be bought for $20. Superglue the magnet onto a spoke of your front rim, then zip tie the sensor onto one of the forks. Mount the display to your handlebar, and pay attention to the bicycle computer instead of your speedometer. If you input the right tire circumference into the computer, they are extremely accurate.

sixtytwo wins this one. Speedohealer only works on bikes that get the speed from the transmission. 250 gets it from the front tire.

What size sprockets? Your bike does 220 mph, no?:nerd

Only down one in the front (think it's a 13). Only does 200 at the moment but I'm working on it :thumbup
 
sixtytwo and TheRiddler are correct. A speedohealer isn't listed for the 250,:(

if you go the bike computer route buy a sigma, they are one of the few bike speedos that work above 60 mph.
 
It's the speedo's way of telling you to watch the road and not it.

Seriously, it'll make you a better rider.
