After deliberating on which type of motorcycle chock to purchase to tow my bike on I opted for the cheap Harbor Freight one. It was $39.00 on sale. I had read that they could cause damage to the bike. I tried to imagine how that could be? I thought perhaps the tires would abrade against the side rails of the chock. I thought if that were the case I could buy some 1/2 pipe foam insulation, the kind that has a slot longitudinally and I could fit that over the side rails to thwart any possible damage. But, I'll see if that is even an issue because I haven't mounted it on the trailer yet. My main reason for posting is that I have the chrome rotor covers on my Ultra Class. They cover the rotors and although they are attractive ( to me) I'm wondering if, before I try to ride the bike onto the HF chock, will there be enough clearance with those rotor covers on? Does anyone have the same covers and tow there bikes without any problems? Thanks!!
