i like the ltr450 the best myself. own a raptor 700 and if i bought a 450 that whould be the one.

 

DS450 for sure. With my rossier pipe so far i have beaten every piped bike i have raced.

 

well the 450r isnt on your list on bikes to get, but my buddy has John Natalies old race quad, which u might see in an old dirtwheels or something but check it out on my page, there not the strongest off the start but when u start modding they really wake up like crazy and are easy to work on and are very durable, so id think of that possibility also, kfx450 dont get me wrong there fast and everything and have a strong motor but i just dont trust there durability, yfz 450 would be my personal choice, best all around bike, very comfortable bike, whether track or trail you wont be dissappointed, IMO the DS450 and KTM450 are very nice also but u gotta have $$$ lol hey if you got the money just go out and buy the KTM525 and put everyone in the dust lol

 

the standard yellow ds450 is a good price, i got mine for 7200 out the door.

then about a month or so i later i saw a different dealer selling them for $5800! to make room for the 09's.
