If you were to pull off an exit and shut your bike down immediately, it would be as cool as it's ever going to get. Trouble is, nobody lives at a rest area so the bike just keeps getting hotter from the time you exit 'til you get home. In this heat that means about 225° when you hit the driveway. The engine can take that but if you want to try to ease it's pain you can pull in, set a fan pointed at the radiator and then after a while start the engine for a few seconds to clear the bearings and circulate cool water in. Cool-down is not exactly unimportant. Heavy equipment operators go through a regimented cool-down process at the end of every running. Why? The engines are expensive and they want to make them last as long as possible. Cars actually have it much easier. When you sit at a light in your car, the engine is cooling down. On your bike, it's heating up.
