What is the difference between KTM EXC and KTM XC-W?

Answer 1

Basically, the XC-W is the same as the older EXC models. XC stands for cross country, XC-W stands for cross country- wide ratio transmission. The EXC is the enduro cross country bike, that is now set up with a headlight, tail light and very restrictive silencer for road riding. The EXC is street legal out of the crate. The XC-W is the race bike that comes with a Motocross number plate on front but has the wiring harness and headlight switch, plus a wiring harness for the tail light as well. You can take the EXC and derestrict it and change the jets and set it alongside an XC-W that has the lights added and you will have the same bike.

I have the XC-W that I have made street legal for dual sport rides, but it still rips through the woods.

The EXC is also more of an Enduro and the XC-W is more of a racing bike so the revs can be pushed higher.
