    Hello All,

    I am wondering if there are any fender swaps (maybe with a little modification) that I could switch out my faded rear fender with...? The bike is a 1999 KTM 640 Adventure-R.

    Also, would it be possible to modify the subframe (i.e. cut and weld) to fit a different rear fender? Or is my bikes subframe the same as the newer Adventures? The 03+ ones... I like the look of that whole assembly.

    Thanks for any wisdom! :clap

    The subframe is slightly different on the newer ones.

    The cross member at the top back sits a lot higher (arched), on the older ones it is a flat piece of metal.

    I have older plastics on my 02 (same as the 03 etc) but the mudguard (fender) sits up at a bit of an angle so I will be replacing the crosspiece as soon as I get around to buying a welder.

    I also have a 93 LC4 that I put my newer rear plastics on.

    They fit OK but you need to fit a 01 or newer seat because they sit higher.

    Before.

    I painted the rear fender on my '99 with the Krylon Fusion orange paint. It's almost a dead on match for the orange on the rest of the bike.

    If you go with the newer fender the seat will also not match up with the plastic.

    While this is mostly a picture of the seat you can see the painted fender just a bit at the back.

    You could try a heat gun to restore the faded plastic. Just start on a low setting and work upward to avoid melting the plastic. And don't touch it until it's cooled.

    Thanks for the info.

    tHEtREV - So the only difference in the subframes is that the crossbeam is different? If I were to put the newer model fender on my bike, it would bolt up, except I would have a gap underneath where it sits on the crossbeam?

    Also, thanks bisbonian. I may go this route as a temp fix.

    From memory the newer plastics bolted straight on, but as I said, a newer seat is needed.

    I'll be down working on them in the next hour or so, so I'll double check and get some measurements.

    Great thanks!

    I figured I would need a new seat. I need a new one anyway, the thing gets too hot and uncomfortable!
