Installing a Sigma bicycle computer

From Ninja250Wiki

Notes: There are a couple things to remember before you get a bicycle computer for your bike. The following articles are a couple years old, and, as you may have noticed, electronics companies change models with the seasons these days. So, the models that are mentioned in these writeups are no longer being manufactured.

Just go to Sigmasport US, look at the specs, and find the one that best suits your needs. The way you mount them hasn't changed. Just remember to get a wired version. Wireless won't work on the EX250.

If you're going to be riding your bike after dark, please note that bicycle computers do not generally have lights, and the one model that does requires you to reach out and push a button to turn it on, and it won't stay on for more than a few seconds; not a great idea when you're tooling down the highway at night. Sigma tells us that if the light was on all the time, the battery would go out in about a week. You'll either have to rig up some sort of light that can shine on your computer, or go to the streetfighter article and look at the companies that sell gauges that are wired into the bike's 12 volt system.
