I see KTM's choice to increase new Adventure displacement to 1190cc very logical - all other bike manufacturers are making1200cc bikes - BMW, Triumph, Yamaha. It's hard to compete with 990cc bike in 1200cc class and attract new customers.
I see KTM 690 competing more with other 1-cylinder bikes like BMW Sertao and Yamaha Tenere.
That leaves new 800cc multi-cylinder Adventure bike class (F800GS, Tiger 800) somewhere inbetween - it would make a lot of sense for KTM to come up with new bike to compete with BMW and Triumph. I would expect ca 100hp (like original 950) and 170-180kg (sub 400lbs) wet weight. Let's hope for the best!
