Speedometer correction is serious business. That’s why we’re talking about how your speedometer can get out of whack, why it matters, and how to fix it.
That’s because nothing’s more annoying than having an unreliable instrument panel. But that’s exactly what bigger tires and a gear reduction do to your UTV’s speedometer.
When you upgrade, your speedometer stops reading correctly. That’s not just frustrating—it can also be dangerous and illegal in some situations.
So let’s look at why speedometer correction matters.
The reason your speedometer reads wrong isn’t because of some defect or damage. It’s because you’ve changed something about your machine.
Changing your tire size is the main thing that messes up your speedometer (and probably the reason you’re reading this right now).
When you upgrade to bigger tires, you travel farther with each rotation of the tire than you would with smaller tires. Since your UTV doesn’t know you have bigger tires, it’ll say you’re going slower than your actual speed. This also means that your odometer will tick up slower too.
The opposite happens if you switch to smaller tires. Your speedo will say you’re going faster than your actual speed, and your odometer will tick up faster.
Changing your gear reduction messes with your speedometer in the same way. If you get lower gears, your UTV will think you’re going faster than you really are. Your odometer will tick up faster than it should too.
It doesn’t matter what form this gear reduction comes in. Whether you’re rocking a transmission gear reduction or a GDP Portal Gear Lift, your speedometer will read wrong.
If you install high gears for a higher top speed, your speedometer will read too low instead.
So your speedometer is wrong. So what?
You’re wheeling on off-road trails anyway. And when you’re not, you’re on private fields or open dune parks. It’s more about feeling the speed of your machine than reading it on a dashboard, isn’t it?
Not so fast, buddy.
There are several issues a wonky speedo can cause.
An incorrect speedometer can cause lots of problems in lots of different situations. It’s worth fixing.
So how do you correct your speedometer for larger tires or a gear reduction? It sounds tough, but it’s straightforward if you have the right tool.
That’s why you need something like our SpeedDoctor Speedometer Correction Kit.
The SpeedDoctor is a little device that plugs into your UTV to override your dashboard speedometer. A quick calibration will fix your speedo, so you don’t have to second-guess your speed anymore.
It’s not a completely universal gadget though. Currently, we have SpeedDoctors for many models for:
