I am 5'7" and come from a mountain bike background. When I ride my buddies bikes (they all hve four strokes) the bikes feel real heavy and cumbersome. Who makes a bike with a low saddel hight and ight wieght that still has some guts?
I would look into a Gas Gas Pampera. Very low saddle height, lots of power. I have a KDX 220, and I am 5'8.5", and I have made some modifications to bring my bike height down. Had I to do it over again, I probably would have bought a Pampera. I also rode mountain bikes for many years, and know that you become acustomed to about 2 to 3 inches of clear space when straddling the top tube. Makes the bike much easier to handle in the woods. With my Kdx, the feeling is really high up, and the weight is 218----a pampera weighs in at under 200. Check it out before you buy.
