Here's a question for the group...
Should someone do a fly and ride out of state, how would you handle the break in period considering the amount of super stabbing that might occur?

Your owners manual (page 6-3) states that what should be avoided are:
"...do not put an excessive load on it..."
and
"...During this period, prolonged full throttle operation or any condition that might result in engine overheating must be avoided."
and
"Keep the engine speed out of the tachometer red zone."
What I do not remember is the sticker with limits of rpm for the first hundreds of miles.
While we do already have other threads about breaking, the bottom-line biggest goal of break-in is to keep cylinders from glazing which prevents the piston rings from seating. The second biggest goal is to create what will be the engine's wear pattern on gears, cams, and other sliding surfaces. While there are all sorts of opinions about how long this can take, aircraft engines have for decades had very clear break-in instructions prescribed in minutes and the total is 2 hours. Ref:

While nothing in the Yamaha guidance says to stay off the highway and highway use would be very similar to the steady throttle of helicopter operation, you could avoid any question by simply running the first 2 hours off of the highway to be comfortable. This will let the engine run up and down through the allowable range, allow the gearbox to spread wear among the gears and shifting forks, etc.
Go do your fly-n-ride and enjoy the new bike!
