+1 on this one. I have heard this debate a few times myself and to each his own but I back this method myself. When I did mine I did it by the book. I mean doing the "hard" break in method may work and might make the engine feel stronger but is it gonna make a noticeable difference compared to a break in done by the book......I highly doubt it. My bike screams and I take it to redline quite often and it does not lag on me at all. Also when I took my bike in for it's first valve adjustment the head of the service department told me he had never seen a busa's valves so perfect on a busa. They were DEAD ON Zuks specifications at 13,000 miles and everything in the motor was sealed up properly. So knowing that the next bike I get will be broke in the same way. I think that the hard break in when the motor gets some high mileage on it will produce trouble but thats just my thinking. I mean like u said if the Zuk engineers that MADE and DESIGNED this motor say to do this I am apt to believe they know what they are talking about. And as good as my motor has done off of it I am gonna stick to iti broke mine in by the book... bought it new like a month and a half ago. first 500 under 5000, then i dint remember the rest but its in the book. I did 670 miles after the first 2 days and took it in for the 600 mile service. I did it by the book for longetivity purposes. Sure you can break it in hard and it will feel stronger MAYBE, but, if you break it in by the book you have a piece of mind. There were a room full of engineers who came up with this procedure, i'm sure they know more than any of us. I want 100k on my busa with no problems, just follow the book for 1100 miles or whatever and you'll be fine. I put 1100 on literally within 7 days of owning it. I now have over 3500 just because i've been busy with school. 110 is achievable at 5500 rpm
As far as the engineer part I think it is more manufacturer CYA than a technical study. I have worked with engineers for years and that surely doesn't give me any comfort. They all have their own opinion and then spew a lot of crap to back their point. 3k to 5k rpms with a lot of accel and decel for 20 minutes. Let it cool down for 20 min. Ride again for 20 mins with 1/4 to 1/2 throttle accel and hard decel to seat the rings (5k to 7k rpm) and then let it cool down. You are heat cycling the engine because it will have some hot spots. Change the oil (should be around 50 miles or so). Ride varying your rpms with a lot of accel and decel going up to 9k accel as you want. Just don't lug the engine at all. Change your oil at 500 miles. Work toward redline briefly. Change to synthetic oil at 1500 miles.i broke mine in by the book... bought it new like a month and a half ago. first 500 under 5000, then i dint remember the rest but its in the book.

that's too funny, Jesus did the robot toomy Breakin' period was back in '84 thanks to people like Turbo and The Electic Boogaloo. I could jostle my feet, do a robot, wave my arms, and spin on my back and head quite a few times if you threw down a sheet of card board.

Suzukis full of it and i don't mean oil. After 3 2500 mile oil changes I have yet to be even 1/4 a quart low.per suzuki a busa will use a quart of oil every 500 miles as normal consumption
I was wondering if I was the only one that caught that?that's too funny, Jesus did the robot toomy Breakin' period was back in '84 thanks to people like Turbo and The Electic Boogaloo.

Load it (hammer it), shift to upper gears to let the engine cool slightly then hammer it again.
I've always broke my stuff in like this even before I knew what was going on. Break it in like you're going to ride it.
Please cite a reliable source that proves a bike broken in hard has more power than one that was broken in according to the manual.with 29 miles on my busa i ran up to 180 and kept running it hard and i am at 27k with no problems. these bikes come out of the crate ready to go you just need to scuff the tires. it will run like it is broke in so if you want a slow bike follow the manual.
