would be nice for a bike larger than Scout, smaller than Classic-650# bike or so.
I think the Scout has that displacement range covered with the 69 ci (1130 CCs) and 60 ci (983 CCs) engines. It seems like there is a big gap between the 69 ci Scout and the TS111 (1819 CCs). I would think that would put the Spirit or Warrior somewhere around 85-97 CI (1400 to 1600 CCs). Then the questions would be liquid or air cooling? Stick with V Twin or try something different? V angle?Yeah, like a Spirit or a Warrior with somewhere between 900 & 1200 CCs.
I suspect a water-cooled V-4 of around 140 horsepower in a bike splitting the difference in size between Scout and Chief (I look like a bear on a mini-bike when astride a Scout) would sell like hotcakes.What might be interesting, though, is if the modern Indian 4 were a V-4, allowing for classic good looks with phenomenal power. Also very different market than the Chief, if anything they might be stepping on Victory's toes.
