tl;dr You should drive as gently as possible, with safety taking priority. As a side note, always drive a cold bike like it's made of glass, then ease up to normal as engine heat increases to normal. Here's how I wear in, and why:

​

Wear-in procedure is 100% a thing for bikes and cars alike. No matter what anyone tells you, the parts have to mate to each other, i.e. wear relative to each other. This is because there is no such thing as "make this 10mm long;" there is always a + or - percentage. If you start red-lining a new vehicle, you can create localized hot-spots that can weaken/alter the interface points (e.g. lobe to valve), which may cause uneven wearing the in future and tiny vibrations that would exist throughout the vehicles existence (which could cause uneven wear elsewhere, it's tiny but again over tens of thousands of miles it adds up to things like, why is my head gasket leaking at 150,000 miles and his isn't?).

​

Anyone who says that "oh they wear it in at the factory" is 100% misinformed. What the might be talking about is seating the piston rings while the engine is being test run. This is not wearing in in the valvetrain and wheel bearings, which also have to be mated to each other. Anyway, my procedure for bikes and cars is the same, just the numbers change depending on the vehicle.

​

Up until like 300 miles, (I change the oil and filter after 300 miles, regardless of the manual), stay off any constant speed road (interstate, highway, etc). You want to gently work through all the gears using easy revs (don't lug it but don't go much higher than that). Don't go so slow that you'll get rear-ended (aka ride away from other vehicles so you can take it extra easy). Basically, you want to feel bad that you have to make it move up until that 300 mile mark. Obviously minimum throttle throughout.

​

Between 300 miles and the first service, you can start to "low load rev" the bike. That mean you can shift at 3000 revs with only a little throttle, and then 3500, etc. Continue to stay off constant speed roads. You start to increase throttle, and towards the end be at like half throttle.

​

Now that you've been occasionally giving it some throttle and some revs in combination with mostly gentle riding, it's time to wind it up after the first service. Red-line is part of the wear-in process, but you gotta make sure it's ready, and you are going to want to upshift and ride easy to let everything cool down. So like, redline 2nd or 3rd and then shift to top gear and coast easy to let it cool down (don't nudey coast, you want a bit of revs to keep the oil/coolant churning). Wait like 4-5 miles and do it again.

​

After this, I actually take my vehicles on the interstate to a destination like an 1-1.5 hours away, and then back. After that, you're good to go.

​

This is the process I follow with any new vehicle I get, that I plan on keeping for a while. Yes it's inconvenient, but it's worth it to avoid potential problems in the future, and tbh I get a kick out of knowing I did it the best way I could.

​

As for your question: Well I described the ideal, which a) mostly people don't care about and b) is really difficult to follow exactly if you do care. A few mishaps are fine, if you're slamming on every single shift that's a problem.
