I'm looking into my first scooter. I've been legally riding and owning motorcycles since the 60's but no experience with scooters. Been focusing on Vespa's new 300cc models, but the price for the 150 variations is much cheaper. I need to be able to cruise at 55-60mph "without" the motor being wound up/maxed out. I won't be doing interstates rather just 2 lane hwys and some dirt roads. Will the 150's handle those pavement speeds on a regular basis w/o constantly stressing it and prematurely wearing it out? I'm retired so income is very limited for future major repairs especially those due to abuse.
