The new steel-trellis frame might look the same as on the 750, but it’s stronger and stiffer and hence a little heavier. Aprilia has compensated a little by making the rear subframe lighter, but there’s no reason to think that improvement won’t benefit the 750 in the future. The Dorsoduro 1200 tackles the corners with great agility and that supermoto feeling where you can place the front wheel exactly where you want.
The Dorsoduro 1200 is a fairly heavy machine (457 pounds claimed dry weight) compared to something like the Ducati Hypermotard but with 30 extra horsepower to compensate. The chassis is ultra stable for this type of bike. Nailing the throttle out of first and second gear corners there’s nothing but smoothness with the correct traction control and riding mode selected.
