Speedometer inaccuracy

[Raprider]

Well, a dozen folks seem to. But I'm with you - same with fuel consumption and listing all the special do-dads attached to or hanging off my trike.

Freddy, I was just assuming you have no doo-dads :joke:

My 15' RTS is off about 4 mph. My wife's 2018 Toyota Camry XSE is off 3 mph on Cruise, but only off 2 mph when using the gas pedal. It's not because of the radar Cruise control slowing it for a car in front of it.

With the General, I am .5 to 1 mph off. Keep on ryding.

I have only a few doo-dads, cruise control being one of them. The others doo-dads don't work any more, so the less said the better. :cheers:

But this thread is nearly as animated as an oil or tire thread.

Good morning all,
When I had my 16 RTL I noticed that the speedometer was off by about 2mph at highway speed. I've just traded for a 19 RTL (see photo) and it has the same issue. Am I crazy or have you experienced this also? Is there any corrective action? Thanks for your help. Chris

The difference is to comply with Federal and International law. I explained it all here: https://www.spyderlovers.com/forums...edometer-error&p=955980&viewfull=1#post955980

as far as my experience, most motorcycle speedos are optimistic.
Hey, that 2 % ? If that makes or breaks your relationship with your RT,
then I don't know what to say. Some folks fiddle with tire sizes (rolling diameter) to affect a change.

Land speed racing on a 1 mile airport track with a 132' timing trap at the end. On the top end several motorcycles showed 15 mph higher than actual timing trap speeds. 2 mph at highway speed is fairly close. Tire wear makes a significant difference. A few years ago--OK--several decades ago I had a 53 Ford that would show 103 mph with worn tire. New tires top speed showed 89 mph.

Every bike I've ever owned over the past 50 years has always shown 2-3 mph greater then what I was actually traveling at.
The Spyder has been no different

Hi C.Lee,

I have a 2017 RTL and there is sometimes up to 10km difference between the dial speedo and the digital. Add to the "equation" My GPS shows a different speed again

at 100km/hr on the GPS
The Digital speedo will read 103
The Dial type speed will read 110
