Victory does use the same 106 motor and transmission in all its machines, although the muscle cruisers and tourers get different cams (I believe). The company makes full sized cruisers & tourers, and the 106 is a proven bulletproof design appropriate for that type of motorcycle.
They haven't yet found excuse to make a starter bike, dual sport or sport machine. After all, they haven't been around for over 100 years (yet).
Those things take a big investment and Polaris isnt up for that yet. They are staying in the cruiser/touring market because their research proves it has the highest actual transaction price and greatest profit margin per unit. Engineering a good <1000cc engine, adventure type dual puropse chassis, starter (or right-sized bike) etc then increasing production capacity for a lower return isn't going to happen at Victory anytime soon. In short they do not have the commitment to being a full range motorcycle company.
With Harley its a different matter. They could IF they wanted to but they feel it would have a negitive impact on their all important image. Even when they had Buel they were carefull to keep it seperate from Harley. Hell even Sportsters are considered "girl bikes" in the Harley world. Marketing has the Sportster as a "get them in the door" price point motorcycle, with the intent to trade-up within 1 year to a "real Harley." I looked at a V-Rod a few years ago and the salesman had to go find someone who knew anything about "those bikes" they kept only one in inventory and it was clearly not considered a real Harley either.
