I own a 98 Kaw Kx 250.. I think its time to buy a new bike. I ride MX and FMX, and my Kx has always felt a bit bigger, wider, and heavier than the other bikes. I was wanting to know if anyone knows which bike (2002 YZ, RM, KX, SX) is the lightest. Im NOT trying to start a brand war here... just wanted to know who makes the lightest, most flickable, MX'er these days. Any help is greatly appreciated. Also, are the new super 4-strokes (YZF, CRF) manueverable enough to ride FMX? Ive never seen any pro FMX'ers on them yet except for Trevor Vines, who was on a Yz426F.. and now back on a 2-stroke. Just need some of you're opinions. Thank you very much.
