I weigh 160 lbs. and ride 2-up with my wife about 35% of the time (290 combined). I have a 17" Clearview SS replacement, 18T, AI & snorkel removed, 128/42 jets and SS exhausts. I consistantly get 133-138 around town and 140-145 on the highway (solo). I have never gotten over 145 under any riding condition during my 4000 miles. I'm a moderate rider and my around town traffic is a lot of stop and go.
