I have been looking at the 650 savage for an up-grade from my Rebel 250. I was concerned about the one cylinder engine of the savage. I drive 30 miles one way to work and I was wondering about the endurance and the vibration (if any) of the savage. The drive is 4 lane highways and interstates all the way and I won´t to be comfortable both in all the traffic and on the bike. Any helpful information would be greatly appreciated. Thanks, Keith.
