Thread: best mods for my 05 rmz 450

I run 14-51 for MX and most offroad, 15-51 for desert races. 13-47 is nearly identical to 14-51, so I'd recommend trying...

Haven't tried the FMF on the RMZ but they make good stuff. I wouldn't bother spending the extra $$ though. A Quick Shot accelerator pump cover will help with the off-idle bog, or you can do the very cheap o-ring AP mod at the top of the Intake forum.

Im interested in that too I have the same bike. I heard all those mods dont do much except for a high compression piston setup which is about $800.00. But if you get that your bike will go insane.

if u can afford to go with a ktm 450 xcf or 505 that be a much better choice the ktm lugs down better and has more power , if ure interested im selling my fmf megabomb header and a brand new thunderalley exhaust i will sell cheap pm me for more info

I have a 05 RMZ 450. Biggest performance gain was the FMF Ti Pipe and the mega-bomb header. It's awesome. With all that said. An awesome pipe that increases power on a bike with bad suspension is just as good as a clapped out engine on a bike with bad suspension.
