Engine break in

The time is nigh. I plan on getting a brand new bike by month's end here.

I have never had a brand new bike with 0 miles on it and there is the hugely controversial topic of break in that I have yet to go through.

I have been doing research for a while now and I would like some opinions and if anyone has any experience doing "aggressive/accelerated" break ins? Specifically on a dyno or at the track.

I know myself and I'm not going to be able to go through the "by the book" process.

If craps going to break or have issues its going to break n have issues regardless of what you did during the break in period. Its new and has a warranty n extended one if you get suckered into buying it...

Rode my new yamies reasonably hard, break in time is for you as well as the bike. Make sure you get use to the bike before being crazy...

I made sure to not bog it down. Use all the gears and RPM range, didn't stick to one rpm for too long for 300-400 miles(The standard crap). Did the last 100 at the track to work the upper end. Test everything abs, traction control, throttle maps etc...

Ride it like yer going to ride it...My 2 cents.

Are getting the FZ10? And are you selling your FZ1?

Billion threads on this out there.. The most important thing I've heard from pretty much everywhere is that you don't want to stay at the same RPM for long periods of time during the break in period. Rev it up, engine brake, keep moving around in the RPM range.

Other than that, everything else seems to be opinion. Some people say don't rev it hard. Some say spank the shit out of it. Who knows. Ride it and it'll probably turn out just fine.

I didn't do anything special on my Triumph - kept it under 7K RPM for the first couple hundred miles and slowly worked my way up to redline by 500 miles after that. After the first oil change, I gave no shits anymore.

When I was riding my Ninja 250 home from RMC I did about 6 WFO's from 4k-10K in 3Rd, slowing down on compression in between, by the time I got home the idle had gone up to just over 2,000 Rpm from just under 1,500 Rpm as purchased. From that point on I pretty much considered it broken in.

I have also gone by the book with great success

I've been using the "break it in like you'll use it" method.

well if anything goes wrong I guess you can get away with it since bike is still under warranty!

Pretty sure exactly 0 people in the world have ever 100% done that on any bike they've owned. (Save for newer Euro bikes that are hard limited).

Going off memory - I can pull the exact numbers when I get back home and look at the manual - but for a current gen Kawai 636, you're supposed to be in 6th gear @ ~35MPH. I think the upper limit on how high they want the engine to go is like 6k RPM.

You try doing that for the first 600 miles - I dare you.

I'm not sure I could even physically shift through all the gears from 1-35MPH that quickly while accelerating at "car-in-traffic" speed

Soft break-in if you're trying to set records for how many miles you can put on an engine.

Hard break-in for everything else.

You get 1 chance to set the ring seals. You have about 20 miles to do so. After that they are set until you replace them.

Well I put a deposit on the only grey FZ-10 I could find. If everything goes to plan I'll be taking it to the Ridge next Saturday to put it through it's paces.
