used these now for the last 18 months and found them to be better than the power commander 3.
reasons being- once you have bought it and you change bikes you can just buy a new link harness (about £60) fit it to the new bike and have the new software installed thus saving money. it has 4 map settings changeable at the flick of a switck (on the move). and also available is a QuickShitter to plug into it. how good is that?
