Trail Tech’s Vapor dash is the most suitable for street riders since it offers a bar-style tachometer (as well as a numeric display) that reads to 12,000 rpm. Other functions include current, maximum, and average speeds, tripmeter, odometer, ambient temperature, engine temperature, and more. The unit offers several customizable display modes so you can tailor the layout to your liking. The backlit screen is about 3 inches wide by an inch tall, and the Vapor itself is just 4.2 x 2.3 x 0.9 inches. Snapping on the accessory indicator dashboard shown here ($55) widens the dash by about an inch and allows you to add up to four indicator lights.
