what mods/changes can i make to get a 450r to suit my height for track racing. I am 6'7 230 lbs and i really like this quad. Thanks

 

Whatever you need....... if the bars feel low get a riser and some nice Renthals.... If the seat feels too low get a desert racing seat with extra thick foam to ease the bend in your knees when seated..... there is an endless list of aftermarket parts for the 450R ......

 

I think about the only thing you can do is get a longer steering stem and that is about it.

Not to tell you to get away from a great machine like the LT but you might think about another quad such as the Raptor 700 or a DS 650. I am only 6'2 and cannot fit on a 450 comfortably I cannot see how you you cana! LOL This is why I went with the Raptor. Sorry if this not much help!

 

its fine but i tend to be able to manage on smaller things, i ride a gsx-r 600 and my downhill mtb frame is a medium, so gah im in a debate between 3 quads..... the ds650 the lt 450 and the banshee

 

I realize this is a bit of an old topic, but I feel your pain. I'm 6'5 and 275 pounds. I used to ride a friends TRX 450R with very little discomfort. In stock dress it pulled and fit just fine. Might be worth tryin on if your lookin for a good sport quad to run. my .02

 

I'm 6'4" and simply switched the handlebars for a set of ProTaper CR high bend bars. Originally was going to change the steering stem for a +1 stem, but didn't need it after the bar swap. Just an inch or two makes a HUGE difference in the feel of an LTR.
Keep in mind that the 'zuk is lower and a lot wider than a Honda 450R, so the bars are already a little taller in relation to the bike's center of gravity.
