Modern dirt bikes are more reliable than ever, but it is important to ensure that a regular service schedule is maintained. And one thing with dirt bikes, there isn't the traditional schedule to adhere to. It comes down to hours on your machine. Ideal intervals vary depending on the mechanic you're dealing with, the level of abuse the machine is copping from the rider and your own level of concern for your machine. But to keep on top of the time your machine has been in action, a Works Connection Hour Meter is hard to beat. These units offer a lot more than just engine run time and can give you a clearer picture on the treatment you have been dishing out to your machine as well with Max RPM recording, and Auto-Reset functions.
