i noticed u said ktm the standard ktm 450sx is 11,500 the xc is 10,699 or u can go with the 505sx for 11,800 i personally like the can am ds450 for 7,499 and those come in an mx version for 8,949 or a xc version for 8,749 and they both have all the goodies u would buy to put in the yfz like like piggyback shocks kyb hpg c40 aluminum piggyback rear shock itp gncc holeshot front and rears and they have nerfs and the xc has barkbusters and a full skid also honda came out with a trx700xx for 7,999 with a wet weight of 505the wet weight of the yfz is 404 so 101 pounds more for 686cc compared to 449. thens theres the new kawasaki kfx450r weighning in @ 395.7 wet weight i personally think they r some bad ass looking quads and they start out at 7,549 or the monster energy version for 7,849.then u got ur ltr450 very nice price 7,699 or the special edition at 7,799 with a wet weight of 414.5. i almost forgot about the ktm 525xc 10,999
