A Spyder will take more effort to turn than a motorcycle, or even an ATV. You have to physically steer it into turns, unlike a motorcycle, where you countersteer slightly, then lean. Since most of the speeds are higher than an ATV, there is more straight-line momentum, so you have to steer a bit harder there, too, IMO. Spyder steering is just an assist, not full power steering, and it is proportional, so it reacts differently under different conditions. If you think you may have problems, compare to a dealer's demo, or have another rider try yours. For most of us, there are no issues, but we do get more of a workout than motorcycle riders, for sure.
