If not I would look at the tyres first as well. Recently, I can feel my car shaking when I try to accelerate. While the fuel injector starts pushing more fuel into your engine cylinders, the air drawn by the engine increases exponentially, the crank starts rotating at high velocities, the rpm rises and all these in effect make your car move very fast. The 2012 Honda CR-V has 7 problems reported for vibration when accelerating. None of them seem to mention if it only does it while accelerating like mine. I only get the shudder when I accelerate while moving. In addition to being susceptible to engine vibration, a propeller produces torsional excitation which varies with rotational and translational speed, flight attitude, airframe characteristics, and the specific properties of the engine torsional excitation which are applied to the propeller. That Piaggio engine is pretty bullet proof and the clutch should be good for 20,000+ miles with the belt/rollers good for around. When lifting the foot off the gas, the vibration stops, even at very high speed (ruling out any tire or wheel balancing related issue). If you coast at any of these speeds it is NOT present or significantly reduced. I felt a strong vibration from his car as the speed increased.
