Are there any aftermarket shells made to fit my '01 200?
Yep, all sorts. If 'fit' means can you bugger one on??
Maier (sp?) makes a KDX look-a-like. Has a square type lens. Acerbis and UFO and others make units that strap on..not bolt on. Those are usually 2-light (round ones) units.
Basically, pick one you like.
BUT...be aware that many of them will require you to purchase/rewind your existing lighting coil. The stock KDX is good for 45watts. That's a 35W front and a 10W rear. Put a dual Acerbis on a KDX that has a couple of 35 watters..and it will be very dim. Effectively useless as a headlamp.
Also, some units have no baffle on the back of the lamps. The light off the bulbs into your face in the dark makes it hard to see. Make sure the unit you buy comes with some sort of guard to block the light from the rear of the shell.
If the shell you really really like doesn't have a baffle..you can take the bulbs out and paint the backside of them. That works on my riding buddy's bike.
