OK Im new to posting usually just search and read everyones great advice.I searched for this topic but found nothing. Im 34 215lbs 6'3. I mostly trail ride but where I ride(duramtown in georgia) there are some nice jumps on the trails and they have some mx tracks also that I would like to get into.my 01 wr250 had plenty of power but on the jumps it landed pretty hard and I hated the decomp. crap.I got a good offer ($2400)so let it go.now Im looking at 2 bikes that look to be about in equal condition(very good). the 03 yz450f looks almost new,bone stock,very fast.the 05 yz250f looks to be in good condition some after market parts nothing major I know of. $2500 which is the better bike.seems like the 05 would be more advanced but the 450 is a 450!!
