The 950, with its FI and belt drive is much more powerful and smoother than the 650 , in highway riding. More power, lower RPMs, and a longer wheelbase make the 950 more enjoyable on longer rides. It is also heavier, but not noticably so, unless you have strong crosswinds. I had ridden my 650 to Waco Tx. And back from Dallas, Tx.about a year ago. While it was doable, the stock seat just wasn't all that comfortable. Just last month, I rode my 950T through Waco, all the way past Austin, and was much more comfortable with the stock seat. Mileage on both bikes was comparible, but the 950 gets the nod for the greater horsepower. HTH!
