When activated, the rpm will be held at a steady rpm and once the green light comes on, release the clutch and take off - but be sure to hold on! The rpm is adjusted with two built-in rotary dials ranging from 1,000- 10,900 rpm in 100 rpm increments. A handy LED shows when the launch rev limit is active.
