Benelli TRK 251 acceleration + top speed

I was offered to exchange my SWM Silver Vase 440 for Benelli TRK 251, I had known it was going to be weak but the top speed suprised me :) In the end I decided to keep my SWM but Benelli, considering it is only 250 ccm, is really nice bike full of technology (ABS, USB, well functional windshield, LED lights, 6 gears, LED display, ...). It has not enough of torque (compared to the 440 ccm SWM engine), but I can imagine to travel long distances in speed much higher than 100 km/h, even on highway.
