Im 5' 6" weigh 165. I rode many 125-2strokes (week) 250 2-strokes(own) and then just recently I road a 250F Kawasaki 05 and fell in love with the height, handling, Power. I gained so much confidence just from being able to plant my foot and turn hard. Hills is the second place I found the bike to be more manageable. First thing that you might want to do when getting a used bike is have the rear shock recharged then service the front forks and then have the spokes tightened professionally. More than likely this bike you buy will have been neglected so invest in new wheel bearings and breaks. Your bike will be completive. Next you have to have a good set of knobby and do yourself a favor stay off pavement it will chew your 80$ tire on the first run! PS stay away from backfiring 4-strokes! Good luck
