lifespan?

if a bike is not broken in properly, whats the life span? i completely forgot about of the break in period on me 600rr, i guess it was just the excitement of riding...  

i wouldnt trip too much. just keep your maintenece up thats the key to a long lasting healthy bike. not the break in period  

i asked one of the tech guys at the Suzuki shop and he said...after the first 100 miles and even less but he said, "You're going to ride your bike like you want to ride your bike...It will break itself in by learning from you."  

I have heard some guys say take it easy and follow the owners manual. And, I have heard others say "ride like you stole it to breakit in....................???????????????????????  

I've got just about 12,000 miles on my Gixxer 1000, and I didn't really follow the break in.  I rode it like a bat out of hell (first stock rear tire only lasted me 1734 miles! LOL)

No problems--runs as smooth as the day I bought it.

Of course, I'm not planning to put 100,000 miles on the thing.

Oh--and I ALWAYS use the clutch when shifting!  

I wouldn't think that it would be all that big of a deal, cause think of it this way-even if you were riding pretty hot at the start, it's mostly just excitement and unless your a racer, you're not going to ride like that all the time, and besides it's just about impossible to destroy those japanese engines, especially if you keep up on the maintenence.  You'll be fine.  

You guys really need to read this if you haven't....

This guy is absolutely right...  

If you want the lifespan of a race engine... break it in as as the dude in Caseys post suggests. Manufacturers don't suggest break in procedures just for the heck of it. Nor is it a "teaser" period so you can "get used to" the bike.

In fact, if your motor has issues later that can be attributed to break in problems (they CAN tell if looking at pistons and cylinders) your warranty will be void.

There are guys like moto-dude all over the engine world, MOST would disagree with these procedures for a primarily street machine. Race motor... different story. But keep in mind, race motors lifespans are measured in hours, not mileage.  

Until motoman starts giving out warrenties his opinions don't mean much to me.  Personally I'm not going to baby it all the way to 1,000 miles, but I'm also not gonna abuse it on the way home (or wait til 600/1,000 miles to change the oil).  It's not gonna hurt the motor to use a few more RPMs than suggested during break in, it's far worse to lug the motor or really get on it when it's not full warmed up.  I also think its a good idea to avoid WOT and jerky throttle movements until you rack up several hundred miles.  All that said I know guys who thrashed their R1s the second day they had 'em (first oil change the night they rode it home from the dealership), thrashed them for over 30k miles and not had problems....but I'm still not gonna treat my brand new bike like it's a rental car.  

I guess I read it differently. I didn't see anything in there about thrashing a new bike like a race motor. All I saw was "load the rings hard the first 20 miles before the honing pattern wears off, that way you get a good ring seal." Then change the oil.
If you put it in top gear, coast down, slam the throttle open to load the rings, then chop throttle at whatever RPM, could you not load and unload the rings like that and still stay within the manufacturer's RPM spec? I don't know. I've never broken in a bike.
But I have broken in a Ford 351 Cleveland and a 302. Not that it means anything.
I don't know. Motoman's advice makes sense to me. Maybe I'm taking crazy pills or something.  

I've heard a few guys who break in race engine wring the thing's neck after they build it to break it in and send it to the track ASAP.

I've just gone through breaking in my S3. Triumph is VERY specific about the break in period. The oil change at 500 miles is to get out the semi-synth and the metal debris and get right to the synth oil.

The biggest issues when breaking in are, stay off WOT, don't let the throttle sit in one spot for any real length of time, and don't lug the motor. I stuck to the plan verbatim... I think Triumph has a clue at what they are doing...  

I think they would demonstrate a little better 'clue' if they would install conventional oil for the break-in instead of a synthetic blend, and knock that first oil change down by about 450 miles.
But what do I know?    

I've read all sorts of motor break-in procedures from Formula Atlantic race motors, airplane motors, etc.

From what I've gathered, let it get up to operating temp, and use moderate throttle as you do need adquate cylinder pressure to break-in the rings.  I wouldn't got WOT though, just like 1/3-1/2 throttle.  Also, try to never let the rpms stay constant, keep on going up and down through the rev range.  As you put more miles on, I'd up the throttle and the revs.  

For changing the oil, I read a study done by a university that found that 90% of engine break-in occured in the first hour of operation.  So personally, I'd change the oil at 100 miles and probably again at 500.  But that's just my opinion.
