My opinion,
Brand new bike break in=
Start let it warm through up to temp then ride hard as hell for 30 miles then dump the oil as full of crap.
with fresh oil ride it hard as hell through hills or the track is best up to first service. the harder you ride it the better the rings will seal and will result in better compression thus you will have a stronger more powerfull engine. seriously punish it to redline as much as you can.
Perfect for race engines that will be cracked open and refreshed fairly often, pointless for a road bike. The reason race teams do that is it is proved to help get the max power out of the engine. Anyone using that excuse for a road bike needs their head read. Most average riders wouldn't notice a 15 bhp difference, let alone a 2-3 bhp difference.
Also, as BMW impose the 9000 rpm ECU limitation from the factory that isn't removed until the first service how do you propose to run in a road S1R using your method without invalidating your warranty?
We're lucky to have a limiter. The new M3 doesn't have one but anyone revving past the factory's suggested running in limit void their engine warranties. The cars ECU stores max rev information for the dealer's workshops to discover.
