    Still not quite buying that method is appropriate for Chinese bikes, as the manufacturing methods here are not like what he mentions. He's talking about "modern" manufacturing methods and not the 25 year old technology used in most bikes here. That said, I've never babied any of my bikes in their early life, just avoided long bouts of high RPM running.

    Cheers!

    Quite interested in this topic, as I'll get the bike soon.
    I already heard and read about the "hard break-in" theory, or at least a normal break-in period, without going too high in the RPM for too long, but not necessarly always under a given number of RPM, just as long as you often change the RPM, not only same RPM over a long run (highway cruising for example).

    What do you guys recommend, what did you do for you bikes, and what results can you see ?

    After upgrading to 150cc cylinder, replaced rings and piston, I rode a few kilometres to a hill and climb hill with full throttle. Changed oil after 30km. That was how I break in my GS150. It has been running OK.
    Inspired by the theory, I also ride a 110cc pitbike, hard on engine early, the engine runs OK.

    All the methods might work but I have been going for the easy break in for the last 50+ years.

    So the first 20 miles are really that important? I was under the impression that the break in period was more like the first 500km's.
    Like Fred, i'm soon to buy my first bike and interested in this issue.

    There's a lot of opposing ideas, i'm still thinking i'll take it slow n steady for the first few hundred K's. No prolonged bouts on the revs, but i might stretch it a little in 2nd and 3rd during the first few days of use. That's seems a balanced mix of the two trains of thought...

    I'd be interested to learn what ZMC says on the matter, and how he broke n his Raptor 250G.

    I just ride sensibly.

    On my gsxr600 I had, I just rode around, varying revs. Once I hit 300miles, I wound her up once to about 10,000rpm, then back to normal sensible riding.

    On my pulse I am just riding it. Only riding in 30/40mph zones, although 40mph is 6000rpm which is about the manuals limit, I am not too worried. At the end of the day I am not looking for 1bhp more power because of the run in, its only a 125, just want it to last. Even once it is run in, I wont be going much over 6000 rpm, no point on the route I ride.

    Barnone - Your telling your Age! But glad that method has worked for you. How many bikes you got now? 6? 7? hahhahahaha. I'll probably take it in the middle of both methods.....I wonder How BoostCrazy broke in his XF. Having gotten 20HP with his Mods, I'm guessing he broke it in Hard......

    I think BoostCrazy needs to recalibrate his dyno. No way the XF200 will make 20 rear wheel HP with just jets and can. BTW, He bought his XF200 used.
    Take all HP,MPG,fishing claims with a grain of salt.
