On a heavy bike like a FJR I feel new Pilot ST tires slide around more when cool. After a few miles to warm up they are fine. One a DS tire I don't notice anything. The more powerfull and high reving the bike the more careful you need to be with cold new tires just put on. Seen many sport bikes dumped at low speeds when the rider dumps the clutch with even moderate rpm on new tires. Instead of feathering the clutch they want to show off and pull out quick in first gear with the engine in the power band. Its more of an issue when a camera is present.
