The Indian Scout is a nice bike and plenty quick. It will be easier to handle and cheaper to operate but is not terribly comfortable in my opinion, I know because we had one. The TS 111 bikes are much more comfortable but very heavy and more costly.
The Rocket is like no other bike out there in a class all its own. It is a monster of weight and power but is comfortable and quite easy to ride except is ponderous at slow speeds. All bikes need to be respected but this thing very fast. With right hand control it will putter around like a kitten but of you thwack her she’ll stretch your arms and get into trouble in a hurry.
All that said I have no use for a Scout, it’s a toy to me. The Rocket is a real top notch machine and an adrenaline rush. I generally would not recommend this bike to a very young man advising you work you way up but if you can exercise maturity past your years then it would be a fun ride. You choose and live with it, hopefully.
Sorry if I sound like a condescending old fart, but I am 59 years old with 49 years of experience on motorcycles.
Ride safe my young friend.
