KTM twin is a KTM twin. Keep Oc. I would actually want to include the 690s in here since to me these are all the same application. I use my SE different than some people, probably a 500 EXC would be better, however if I sell my Duc, than a 990 ADV or 1190 Adv would be better for my application.
I actually think splitting is petty. It's just the next generation of an awesome bike.
