The break in is a long debated subject ... best article I read in one of the bike mags, Sport Rider or Cycle World, etc. had a great comparison. Took 2 brand new 4 cylinder bikes, zero miles, and one they broke in according to manufacturers recommendations, the other rode flat out with no concern for “keeping it under 6,000 rpm”. After X amount of miles, they disassembled both motors and took various measurements of wear. There was no discernible difference between one or the other.
It was the best conclusive article on the subject I have seen. So don’t be so kind to your new bike! Gas it and enjoy!
