Accuracy of Speedo

Just wondering how accurate the speedo is, I heard upper speeds above 70 it will be off. any Ideas how much? 85-100 mph does not feel like you are moving that fast....

There are a few threads around here somewhere on this. Basically with the stock sprockets, the speedo is 5-6 MPH high at 70+ speeds. Several have referenced how their GPS speed did not match the bike's speedo. However, changing the rear sprocket to a 44 or 45 tooth (someone will jump in a give the right size) gets the speedo closer to accurate.

44 tooth rear made my speedo spot on at all legal speeds in all gears - verified with GPS.

Before, I was closer to 6 or 7 miles an hour under when my speedo was reading 70MPH with stock sprockets in 6th gear. Similar percentages while going slower. Also verified with GPS.


My GPS is spot on with both my Toyota and my wifes Subaru.

16 tooth counter on my '08 made my speedo pretty much spot on, GPS verified.

Stock it was off close to 10% (indicated speed > actual speed).

Many posts on this, I went with the 16 tooth Kawasaki front, speed is exact, odometer reads about 6% low. I changed it because I don't always have my GPS, plus my revs are down by that amount and less torque on the chain. Changing the rear will accomplish the same thing, however it is the front sprocket that has the least surface area, 16T is a 6% increase over stock.

A 43 tooth rear spocket will get it as close as you can get. Plus a 43 is about perfect for road use both in town and freeway. Also the rear tire can change it up some too.

Agree. I replaced the stock rear sprocket with a 43 tooth and now my speedometer and GPS agree with one another.

Who cares? I want to know my actual speed so I don't have people ripping by if I am way under or be ripping by a speed trap myself if I am over.


Only me or a potential buyer would care about actual mileage. So if the odometer is off a few hundred miles when/if I sell, I don't think it will make a hill of beans.

I don't understand how: if changing to a 16f or 44r sprocket makes the MPH "SPOT ON" how can the odometer "now be off"... the speedo only clocks miles per hour (or KPH depending on your country) and each recorded mile per hour is converted to tick on the odemeter. Does the V have two separate sensors? One for the speedometer and one for the odometer? I'm new here and still learning... if there is only one sensor, both have to change at the same percentage....

It is intentional error on Kawasaki's part. Go run a 10 mile distance on a highway with mileage markers. The odometer will be pretty spot on. But the entire time your speedo was off.

Pretty much every auto manufacture puts a intentional error on the speedo, but not the odo. My Honda truck is the first vehicle Ive ever driven with a accurate speedo.

I just dont see the point in adjusting your gearing, just to fix a speedo. Then I get gearing that I dont like on the bike...

I personally never look at my Speedo when riding. I always use my GPS. The Speedy mount above the V's cluster makes it quicker to look at with a glance.

I worked for a Kawasaki dealership and a consumer had concerns about his speedo accuracy after a ecu update, I told the Kaw Rep that it was out by 5% and he told me it's normal for the speedometer to be optimistic by about that much....lol

I changed my rear sprocket because I did not like the stock gearing.

So you don't look at your speedo! Glad it works for you. I happen to like having an accurate speedo with or without my GPS installed. And the taller gearing fits my riding style better. To each his own.
