You’ll be fine. Slap on the cylinder head covers you already have and come on out.
This is just a nice back roads ride around Oakland county. You won’t need the knobbies, won’t need the beefy skidplate, and the stock handguards are good for one drop at least. 🙂
What kind of 250 did you get? Sounds like a bit of an old wives tale as far as keeping the rev’s under 6k for 1000 miles. That would be several service intervals on a KTM before even being able to ride the thing.
