It is a much more powerful motorcycle !
You can get into trouble pretty quick.
Riding position is much more aggressive.
The forks are sprung for a light rider while the rear is sprung much heavier (200 lb range)
So if you are in the 130lb range the fork springs are OK otherwise springs should be switched out to match your weight.
This will better balance the bike
The front brakes are awesome !
Gas mileage will be 35-40MPG depending how you ride.
First off, it's my dream bike. I just LOVE LOVE them. That said, I caution you on the first bike thing. IF you have a few years of steady riding experience then I wish you happy trails. If not you risk encountering issues. The bike is less forgiving. If you grab a hand full of brake you can end up ass over tea kettle which is sub optimal. If you slip a gear....same same. The power is another issues. Some riders comment "it's all throttle control". That is true. However, throttle control is learned with experience. On so called beginner bikes the moment the rider lets free of the throttle the bike immediate slows down enabling the rider to gain control, not so with the SS bikes.
I'm not saying this to discourage as only you know your skill level. Buyers remorse is expensive and serious injury or worse can be permanent. Many new and experienced riders have travelled this road and for some its too late to go back. Go for a test ride, research the pros and cons. Chat with someone who won't blow sunshine up your a$$ cause he wants to make a sale.
