it depends on you too, and what you are looking for,and what your price range is, I has a friend just ride a sportster across country twice, so the reality is what can you afford?
Is the harley davidson sportster a good bike for the highway (65-70 mph) ? for like a 4 hour ride or so? i have heard it is not but i wanted another opinion. if not, what cheap bikes are good for the high way? thanks
Depends on how old you are and how easy you get TB.
But I wouldn't get one for many four hour trips, Sportsters were never designed as highway burners but more for local riding with an occasional couple hour rides.
