I picked up my bike yesterday and found that one of the gauge's is basically a thermometer. I asked the sales guy "what's the purpose" but didn't really get a reason for it. Is it useful for something I'm not aware of? I would think an oil temp gauge would be a better option.
Thanks,

Joe, it's main purpose as best I can tell is to fill the fourth hole in the fairing to make everything symmetrical. An ambient air temperature gauge can come in handy in a car or truck, but when riding an open air vehicle like a motorcycle I can't imagine needing a gauge to tell me officially that I'm either freezing my azz off or I'm roasting. Throw in the fact that Harley's gauge isn't accurate and it becomes even more of a mystery. Harley is big on tradition, even when it makes absolutely no sense. So regardless of customer feedback, and despite common sense, Harley is going to persist in providing you with a cheap inaccurate and basically useless gauge because they have always done so. Please do not try to apply logic to the situation, it will only result in headaches.
btw, the other gauges aren't much better. The speedo and tach seem to be decent, but the rest are just as cheap and inaccurate as the air temp gauge. I think Harley gets the entire four gauge set for about $5. I would prefer they eliminate the air temp and volt gauges, spend a little more on better oil pressure and fuel gauges, and use the two leftover holes for something useful like fresh air ducts or tweeters for the audio system.
