Andrew The GTS will easily exceed twice the speed limit so I think 2PSI drop warning would be the minimum performance I'd be interested in, especially if it "remembers" a given setpoint, i.e. adjust the tire pressure, push a button, & it warns you anytime you're down 2PSI even after the bike has been shut off. I, and most other people, would prefer a monitor to a warning if it wasn't too much additional $$$. Two situations where it could be a tire (& skin) saver are 1) when you're making miles on the interstates & only stopping for gas, running 200 miles/ tank at 80+ MPH; and 2) when you take off straight after work to ride some twisties with a couple of friends after the bike has set for 8-10 hours since you checked the tires that morning. But those two cover almost everything except the ten minute commute to work. As for cost, as you say it depends on performance. IMHO At $100 you should sell a ton, it's less than the cost of one tire. At $500 you'll probably only catch the gadget freaks and folks who've blown a tire in heavy traffic (especially if the wife was on the back) :^). I'm going to post this to the GTS list so it is possible you'll get some additional feedback. I'd be glad to help out with prototype evaluation. Along that line, it might help you to know I'm a research engineer.
