I purchased the Vapor from Trail Tech for $139 and installed myself. Install was basic and enjoyable. The only issue was the sensor that connects to the radiator hose was to small. I called Trail Tech and they are sending the proper one. The proper size is 22 millimeters. It reflects speed, ride time, timer, ride distance, odometer, total hours, rpm's, air temp, engine temp, max speed, max rpm and again it cost all of $139 and I think looks great. Awesome product and great tech support.
