will 05 to 07 400ex plastic fit on a 03 400ex

 

Not without a conversion kit. I have looked for my 03 as well and came up empty. I eventually just bought maier race cut plastics. You could also get fullbore or laker custom plastics. I would avoid all of the hassle of a "conversion kit" if I were you.
I actually asked the same question on this forum and never got a good answer. Hope I helped.

 

do you know where i can get the conversion kit im not big on the race plastic just want to up date the look of my bike

 

Sometimes it pops up on ebay. Not really sure...

 

You can get it thru the Honda dealer, a little pricey but not real bad.
