I really have noticed it can be quite a soft ride and that while at speed, particularly if you transition from one lane to the other behind a large vehicle I get this rubbery sensation like a little headshake, nonsustained, not severe, maybe scary to some but I'm used to other types of riding and it usually happens at speeds well above 60. I thought it was probably the solid wheel thing. Otherwise I would say the V-Rod is a solid ride. I feel the wind with the solid wheel thing is overrated and that probably some are more wary of it than others, not that bad but some get scared a little. But really a shimmy, if you mean by this like when car wheels need balancing and you feel it on the steering wheel or like when you put very large tires to say a Jeep (CJ5) in need of a damper, I have to say, never felt it on my V-Rod, not once I believe. It is not a cheap add on but possibly worth the try. I believe I am a very loose rider (zero tension) and possibly may have passed without notice. Don't think it necessary but I'll pay more attention. Never hurts to learn and seems like that kind of a thread. We'll get something out of it. $150 to try and compare seems steep but WORM swears by it. Seems like an easy install so will follow on vrodjohn experience.
