What kind of acceleration rate and top speed does the 2008 harley sportster XL 883 and 1200 have?

I am 16 and buying my first harley. I have narrowed it down to either the 2008 sportster XL 883 and the 2008 sportster XL1200. Does anybody know what the acceleration rate and top speed of these bikes? Thanks.

HAHAHAHHA a 16 year old on a harley nice… if u looking for acceleration go with a sport bike. I recommend a 2008 kawaski ninja 250r i ride the 07 models and they are a blast
