In the 75 mph indicated range, mine is running at 72 according to my Garmin.

I'm probably pretty close to that.

Re:How fast is too fast? 10 Months, 3 Weeks ago  
Hmm, I would think the odometer and speedometer are one in the same. I rode to Cocoa from home, maps said 50 miles home to destination. Following the exact route round trip was exactly 100. Yesterday while riding on I-95, every mile marker I passed came in at the .2 miles on odometer. What's the difference in speed vs distance? Has anyone actually checked against other vehicles? I drive a particular route for work which is 30 miles round trip via my truck, Roadie says 30 miles too. What am I missing with this 'error'?

I work my way up to speed, when I'm first starting out, 50-60 is as fast as I want to go due to wind. However after a 10-15 miles, 75-80 feels natural. However there are those that don't like it because they have lost their confidence as the years pass and htey start to slow down. My father really doesn't like it above 50, so I try to keep it reasonable for him.

Here is a long article from Car & Driver about the speedo thing.

The way I understand it is that manufactures never want the speedo to read lower than the actual speed and they are given a pretty wide latitude when overstating the actual speed. Odometers are held to a higher standard since they are responsible for recording the mileage of the vehicle.

Kind of like I tell the pencil pushers at work, "What do you want me to make the data show?".

I can't quote the MVSS right now, but they keep them on the bottom end of the acceptable error range to guarantee they don't bust the top end. They would probably have to issue a recall if they were notoriously slow! (on the gauge)

My GPS, the little portable radar thingys that police use and show your speed, and my phone speedo app all show the bike at between 3-4 mph slower than the speedo, depending on the speed. It's a percentage off, as the gap widens with speed.

My car reads a reliable 3 mph higher than actual speed at all times.

Side note, I read a review of a GPS speedometer that criticized its accuracy because it didn't match his car speedometer. Wanted to reach through the computer and strangle.

Might as well throw mine in too. By the GPS my speedo is off by 5 mph. That's at pretty much any speed.

Re:How fast is too fast? 10 Months, 3 Weeks ago  
I caruise 80 on the interstate, from the top to the bottom of the tank... No problems, as a matter of fact she licks it when I talk dirty to her....she like to speed up.... As for speedo accuracy, prior to going to a ct I was almost always 5mph fast on the speedo. always being passed. with the ct, my speedo matches the gps on the button, and I am usually doing the passing. just sayin
