I put Avon Cobra Chromes on my R3 T in December and absolutely love them. Metzler discontinued the radial version of the front tire for the R3T, so technically, these were the only option for radial tires. Handling is vastly improved over the Metzlers. My shop said they’ve had great feedback from Honda Valkyrie owners on Avon Cobras. They’re getting 18K miles out of the rear tires if you can believe that. My mechanic is a big proponent of over-inflating tires. 42psi cold; check the pressure at least once a week.
