At the bottom of this page is "Similar Threads" Lots of Q & A on racks there. At the top of the page third from the right is search. If you punch in "Rear Rack" over thirty threads will come up. All pretty good reading on "Rear Racks" Kelly over @ MotoSportz make a nice one. And just happens to be a Sponsor here at CH. The OEM one for the 610 bolts up nicely too. TE-510
is the 610 subframe the same? i used the search function to begin with, just didn't see anything regarding 04 450 - it looks like the subframes are different on the parts fiche..i know they're slightly different for exhaust mounts.. my rear fender has the tail light on top of it.......................
Our Motosportz unit will bolt up to an 04... http://www.motosportz.com/HVA-SS/TR_details.htm http://www.motosportz.com/HVA-SS/HVA-SS-Home.htm
