Hello everyone. I'm new to this board and a proud recent owner of a black 1125 cr. I have loved the bike so far, but am perplexed when it comes to one part of the break in procedure. When they say "vary the engine speed and avoid operating at any steady engine speed for long periods", how long is too long? What about a 20 minute ride on the super slab with speed varying between 60-85 with a constant speed being held for 5 minutes or less? I know that engine break in theories are in the same passionate boat as motor oil but was wondering if anyone had any solid info. | ||

Engine speed, not vehicle speed. Just downshift or upshift occasionally. | ||

Thanks Moosestang, I should have thought through a little longer before posting. Here's to the intersection of stupid questions and first impressions! | ||

You don't have to roll-on / roll-off continuously either, which would make the other highway travelers wonder if you know how to ride that thing. Ride a few miles at "X" rpm, ride a few at "Y", some more at "Z", etc. Mike | ||

I'll refrain from getting into a debate about engine break-in techniques, but the reason for it is to get a good ring seat, which needs cylinder pressure, which is made by being on the throttle. So when I get a new bike, I'm always either on or off the gas as much as reasonably possible for the entire time I feel the break-in period should last. | ||

I used to up and down shift at one song intervals. I usually ride with music and every song I would downshift until I got to fourth, then back up to sixth and so on. On a lower speed road just do the same to vary between 3500-6000 RPM. No music? Three to five minutes works. Just whatever you do don't listen to Motoman. He's an idiot who's only claim to fame is telling everyone to ignore the R&D that factories put into their engines. The rest of his site is made up of crap from other websites. | ||

Motoman rules. Break in procedures are more written by the legal department that want you to get you to know your bike for a loooonnngggggg time before driving it. This is a low quality video of a friend that met me after I left the dealer with a Triumph Sprint, it had 13 miles on it. The camera bike is a CBR600RR http://www.youtube.com/watch?v=6wUr3LXTDLs sorry for poor quality, | ||

I've run in a couple of Rotax aero engines on home built aircraft. The factory approved method is similar to Motoman but you hold certain RPM for certain periods of time and allow the motor to cool in between runs. The tail of the aircraft is usually tied to a tree (which gets stripped of any foliage in the process  ) for the half to full throttle runs. | ||

You guys crack me up, really you do. I've built my share of extreme performance engines, if the legal department wrote break in procedures then it would be a lot more than 600 miles. Besides, Motoman doesn't even know how rings actually work. |
