Just curious what the engine break-in recommendation will be as far as mileage and RPM? Thank you. | ||

+7 Or the minimum number of recent motors I have broken in with that regimen (except for the 25 mile oil change, I usually do 500-1000 miles, whether motorcycle or car). Buell M2, XB9s, RD400 rebuild, MINI Cooper S (2), base MINI, ZX7,(1989 & 1997) plus a few more | ||

Wow, that is like totally opposite the book. I don't know enough about engines to confirm or deny. What do the expert badwebbers think??? | ||

This would be a good one for anony to chime in on, too.... | ||

well i realize my dad is no not a expert but he used to tell me break it in like your going to ride it. But I would say the safe bet would be to go by the book. | ||

This has been discussed on the BAdweb AT LENGTH... Please search . If we could just let Anonny reply with the breakin procedures in the manual? | ||

Wow, that is like totally opposite the book. Not nearly as much as it used to be. RPM recommendations for break-in were raised significantly for the 07 bikes. IMHO you can now meet the spirit, if not the letter, of the Motoman method without violating the recommended break-in procedure. | ||

I have no solid proof...but it's always been my belief that the "by the book" break-in procedures are more for liability reasons than anything else. Can you imagine the law suits that would be filed if the book said, "Run it to redline under a load". We'd be scooping up newbie riders left and right, especially on a bike like the 1125R.

That is very interesting. I never thought about that aspect. Not nearly as much as it used to be. RPM recommendations for break-in were raised significantly for the 07 bikes. I had no idea as my '06 had a max RPM of 3,000-3,500, or something like that. Damn near impossible to go on the highway without being run over by the cagers. | ||

I'll guess....6,000 rpm max for 1000 miles. | ||

I have no solid proof...but it's always been my belief that the "by the book" break-in procedures are more for liability reasons than anything else. I absolutely agree. It has been shown recently that the very best way to 'break in' a bike is on the dyno or on a track where you can safely vary engine load and speed without having to worry about other traffic. Doing it this way has been documented to result in much beter bhp figures and engine life than normal running in methods. | ||

I believe Matt (Trojan) has it right from all that I have been able to determine over the years of learning and experience building engines. Most automotive engineers and race engine builders agree that varying the RPM's "under load" on the street or dyno is the best way so as not to create particular wear points on critical engine components such as cams, pistons, cylinder walls, valves, rockers and bearings from the harmonics of continuous RPM's. I also like dino oil for break in, as stated, and then full synthetic after only a few hours of engine run in time. The old "break 'em in hard and they'll run hard" is only true if given the proper circumstances. Just my $.02. Bob | ||

I have a favorite "Break In" road that I use every time I get a new motorcycle. It's up on the Long Island north shore and has lots of traffic lights, and lots of rolling hills. It FORCES me to go through all of the gears as well as load and unload the engine. I absolutely stay off of the freeways until the engine is past the 600 mile mark. With the exception of my 2000 M2 Cyclone, all of my motorcycles have been leak free and reliable for their entire lives (two bikes with 100,000+ miles on them). As for the M2 Cyclone, it had "issues" beyond the sort that could've been prevented by proper break in (much as I loved that bike). |
