I didn't do anything to temper my use of this bike and mine runs perfectly with zero oil burn. Of course, as far as statistics goes, that means nothing to anyone but me.

RE: Break in period - Guth_imp - 06-03-2014
Not long after I took delivery of my CB1100, I stopped by my favorite local independent bike shop to show it off. The shop owner previously worked for Honda Racing Corporation and was Miguel Duhamel's lead technician. He has one other person on staff, who was a mechanic at a local Honda dealership for 25 years until they had to close their doors. I feel very confident in their combined knowledge and tend to pick their brains whenever I get the chance. By the the time I stopped by the shop, I probably already had a little over a hundred miles or so on the bike. When the subject of break-in came up, they said to make sure that I had it fully warmed up before doing anything too crazy and to avoid constant RPMs for long stretches. Other than that, just ride it like I normally would, and then some, even taking it up around the redline if I felt like it. Then they reiterated that I should take it easy until I was sure the engine was warmed up. Honestly, I've never tended to baby new engines all that much, although I've always tried to avoid long stretches at constant RPMs early on. Still, I was caught a little off guard by the fact that they didn't frown on visiting the upper end of the RPM range so early on. Regardless, I didn't go there right away as I rarely wind it out that much anyway. Every once in a while though it's fun to experience.

Yes, listen to Miguel's wrench, he is right. I ride my bike like a racebike much of the time, keeping the R's between 5-8 and sometimes getting into the red zone. It loves it. I only have 3500 miles on it but this is how I've broken in every bike since 1983 and some have had 30-40 thousand on them when I traded or sold them, and no worries.
My bike did use a touch of oil in the first couple thousand miles but that is normal for an air-cooled engine during break-in.
Doesn't seem to be using any more oil now, though. Seems practically bulletproof.

Article is exactly correct. Break-in for the engine is 90 percent piston rings. Bearings, gears, etc. don't need to be broken-in, but the rings need to seal and mate to the cylinders, otherwise compression will be poor and the engine will use excessive amounts of oil.Other items on the bike, such as brake rotors, brake pads, tires, and such also need to wear-in so for this reason Honda tell you to take it easy until it's more certain something wasn't put together backwards.
I've found that brakes these days seem to take several thousand miles to really come in. Some guys right away toss the rubber lines and install stainless but I held off on that, and now that the CB1100 is fully broken-in, the brakes are great and I see no reason to change anything. Same was true for my FZ8 but ironically the GSX-R absolutely needed not only stainless lines (I used Goodridge) but a better more aggressive Galfer pad. And those are Brembo calipers.
These days the thing we need to work on is our skills, constantly. They've got the hardware sorted out, meseemeth.

Disc brakes require proper "bedding" to work properly. Basically, this involves transferring an even layer of pad material to the surface of the rotor. The procedure for doing this is not included in any motorcycle manufacturer's break-in recommendations, for reasons similar to those for engine break-in.
Since this thread didn't erupt into a flame war over engine break-in maybe the subject of brake bedding can be maturely discussed here too!

RE: Break in period - metalmaven_imp - 04-17-2015
When you guys say "dont hold it at a constant rpm for too long", what is too long? 30 seconds? 30 minutes...?
I just did my 600 mile service yesterday. There were times even before 300 miles that I held it at a constant rpm for minutes at a time.. Hopefully I didnt hurt anything. I dont really understand why it is bad for it..
RE: Break in period - Lord Popgun - 04-17-2015
I'm sure you will get a LOT of different opinions on this. Its like an oil thread.
30 seconds is not too long. 30 minutes is. The idea is to ride around normally, varying the RPM so as to properly seat the rings (and pretty much everything else). Sounds to me like you did good.
Some ride um like they stole um. I always do the break in.
Now, ask which oil is best so I can sit back and eat popcorn and watch the show
just noticed this was already a 4 page thread. Getting popcorn now!

Did you also notice the thread is a year old? lol Popcorn is going to get stale.
RE: Break in period - Lord Popgun - 04-17-2015
I didn't notice that. Just saw Metal's post is all. Its that recent post thing we have now. I'm blaming that
