Cateye Velo 7 computer install

I used 2 3/8 inch Neodymium Rare Earth magnets, glued in with JB Weld epoxy.

The computer is attached to the dash with existing hole; a longer shaft bolt is necessary. Also the wire is not long enough for the handlebar.

The true speed of 60 registers 64 on the factory speedo.

Nice install, esp the magnet. Just curious though, what is the purpose since the bike has a speedo? I am used to people, esp dirt bikers, using the bicycle units to replace their busted stock speedos.

The factory speedo is 6-7% fast; in a highly monitored hiway stretch, you could end up rear ended because you are going too slow. My 12 mile work commute has 3 speed traps, so I want to be at least going the speed limit, if not a bit over to keep up with traffic. There are plug in computers that correct the factory speedo, however they also decompensate the odometer.

I did this same thing back when I had the V-strom; it was a lot simpler and cheaper than the speedometer healer. The only glitch is that, since the speedometers are made for bicycles, they don't sample very fast, so your speed reading lags a little when you change speeds. They still work great, plus you get an accurate odometer since you can set the computer to calculate based on the actual front wheel diameter.

Front tire diameter?

As you mentioned, you can set the computer to actual wheel dimension. I have new Bridgestone Trail Wings (OEM), and measured diameter at 27 inches which makes the factory speedo overly fast by about 2-3 mph. I was expecting more difference than that. Do other folks have other diameter tires? .

You should expect about 8% difference.
With your cyclometer, you would have much more precision by measuring and entering the wheel circumference instead of diameter.

Definitely will do the comparison. Thanks!

There is a method called the rollout method that makes it really easy to measure the wheel circumference. Just put a spot of ketchup (or whatever you have handy that will transfer from the tire to the floor) on the tire, then roll the bike along a hard surface till the ketchup marks the floor in two different spots. Then measure the distance between the ketchup marks, and that's your wheel circumference, which you can input into the cyclocomputer to get a very accurate odometer and speedometer reading.

Sigma BC 1609

I've been using a Sigma BC 1609 for years now. I frequently cross the border so it provides an easy way of switching between km/h and mph.

Correct speed

I use the Garmin GPS Bicycle speedometer. It mounts with a half turn and I can use it on my V-Strom, YZ450F and on my Specialized. No setup required, no cables and no wheel sizes. Very accurate and it records your entire ride including elevation changes and top speeds. When you get home you can look at all kinds of information on your home computer if you are so inclined. I charge it every couple of weeks.

I looked at the speedo error correcting devices and new speedo faceplates, but they can not guarantee the accuracy of the GPS. It is disappointing in this age of electronics that Suzuki can't make an accurate speedometer.
