. I bought this TT Vapor to replace one on my bike. The previous Vapor has been on my daily ride for 50 thousand + miles. While working on the bike a while back, I stressed some of the wiring and began having problems with the display (no fault of the product). The bike was already set up for the Vapor so install was that much simpler. Setup is easy once everything has been installed and, if desired, contacting TT or a quick Google search will tell you how to set the total hours and odometer reading if you wish to maintain the data already on the machine. I am NOT fond of the company Trail Tech, as I have had many problems with company in the past. However, the Vapor is rock solid and is a great product. My only complaint is that the ambient temperature is always off by 5 to 10 degrees.
