Hardened Valve seats and guides

I know with cars you can replace valve components with hardened ones to get around the fact there is no more leaded gasoline in the US.  Is there such a monster for bikes?

It isn't that big a deal on these motors anyways. The seats are already hardened and any new valves, unless totally cheap junk, will be up to the task. Honda made these engines to run on unleaded fuel. As long as it is done right, and oil changed regularly, the engine will go 100,000 miles before needing another rebuild, if not longer.
The ride IS the adventure. The destination is just to get gas!
