Hmmm, I've been wishing they would build one for years. In the mean time I've been rolling my own out of my little garage.
Lots of guys have done a reasonable conversion out of the Kawasaki parallel twin which is the perfect candidate for what many of you want. Good power, lightweight, bulletproof, fuel injected with good range. All you need to do is rebuild the subframe to accommodate a KTM rear suspension and start trimming the fat.
Plus it would be a crapload cheaper than a new bike
