I agree with shoelessjoe
had an edge, put on riser but also added the shorty seat. it was great, considering I was just trying it at this time.
Then a fuze-bomb which I put a riser on but didn't want to buy thorottle cable, brake cable and lengthen all the wires as needed, added a 2" and wasn't happy but delt with it.
Now I've got a rev with 5" riser and 4" rise in the bars (non x-pkg) when I stand it feels like a dirt bike, good bend in the elbows, no reaching bars are right where I want them. When sitting arms can get tired but if they start to, I stand for 5 minutes and the fatigue goes away. Only issue now is with essentially 9" of rise from the steering post, I can't seem to get the clamps tight enough, they move once in a while, not much but I've noticed 1/2" to 1" movement from the start of the day to the end. usually from riding ditches and driveway approaches or hill climbing, not from trail riding. Still I wouldn't want them any lower. I love my bar height even though everyone I ride with thinks they look weird.
