IS the bike ok on the freeway at 60-70 mph?

My friend owns one of these bikes and the answer is.of course its stable at 70-90 mpg on the freeway, you are talking about a 650 afterall. Some people ride 250 and 500cc bikes on the highway and are fine. The V-strom is a big bike with enough weight to be stable and enough power to maintain and accelerate on the highway. l take it you have not bought the bike yet, perhaps you should search for a forum about this particular bike or Suzuki motorcycles.
