thats what I would do.

 

I just bought late last summer a 1200 Nightster I love the bike but my wife is 6'1 about 200...hope shes not reading this as im 5'8 190 I can ride all day, with 2 up we ride but her butt hurts on badlander seat and she refused to ride it alone due to her height. and yes this is my first bike I put over 4000 miles on it in less than 2 months now looking at a FLHTP go figure rember the sportster is for the hard tail bones out here i just realised that when i test rode the bigger bike.

 

I Had a XL1200 and I am around the same height weight. Without the right seat and a upgraded suspension, it will be a PIA. Forget about 2 up. Solo you will be fine for short trips. Dynas are a nice next step up. However the sporty feel is rather cool and is great for short hops. It is a great bike when you get the stage 1 and has a nice Harley feel to it.
