hi all looking for some advice i want to buy a ktm but dont know what one,i am coming from a drz400sm so was thinking either a 625,or 640,i am 6ft 6 tall so i am a big fella,did not want to go for 660 as me never had a bike with a kick start,i have also got a fireblade so am not coming from a 400 to a 625 with out being big headed so i can handle a bit more power,so i would be very gratefull for any info
