Get those rings bedded in properly to ensure good compression and minimal blow by in the long term. Cruising is no good for that. Rings need firm combustion pressure to force them into the bore to bed in before they glaze up.

I drive my m2c, on average, more gently now AFTER running in.

During run in I only took it out on "run in" drives. At least 45 minutes for full heat cycle, open roads, wide use of revs (5k is plenty), up to 2/3 throttle, drive it enthusiastically. Load the engine, brisk runs to 100mph.

Then get the oil changed (995 miles for me) and relax.

Now i use it normally, odd school run, traffic jams, town etc.
Yep... this is what I do as well! Nicely stated.

I also try to let the engine cool completely to ambient, when possible, before the next full warm up heat cycle drive.
