How long do you want it to last?Long time easy breakin. If you want instant gratification and have no patience hard breakin.

tp555 nailed it.
when i saw the thread title i knew before opening it you could probably get 500 opinions. by the time you finish reading them, you'll see there are exactly two ways to break in a scoot.
1. baby it.
2. ride it like you stole it.

A soft prolonged break-in is bad because the piston rings never get to seat properly. When your piston goes up the compressed air also pushes the rings outwards allowing them to seat with the sleeve, however if you do this too often in a single ride session the heat will be too much and glazing will occur with the result been a loss of proper compression. So Phaze5 is correct by saying let it cool off by normal riding before you stick it again. If you soft break-in, glazing also occurs because the rings are not forced against the side to scrape it clean. Also never let any engine labour and don't idle too long in the morning specially a new engine. Start, idle for max 20 sec just so the oil goes all over then drive gently until she is warmed up and then every now and then give her full throttle for 20 sec or so and relax for a few miles then give her gas again. After about 320 miles you will have a bike that performs like it should. You don't need to do this after say 320 miles because then the engine is properly broken in and your oil consumption will be correct. Too slow, forms glazing and oil consumption is bad for ever. Check google there are many posts on this topic.

avoid driving stop and go, do a long steady drive as much as possible. avoid aggressive /hard driving and uphill driving.otherwise you'll end up with a broken pistons. do moderate driving in one month.

Ride it like you stole it, but do it the smart way. oil, oil oil change change change. do it at 0, 20, 50, 100, 200, 400, then every 800. Like above no synthetic until 1000 K. I did this on my $4,000 SYM and my $1500 Xingyue. Always vary the throttle and don't keep it at this same RPM for too long. The most important thing is to open it up and let it coast back down and keep doing it for the first 20 miles. It will get very boring, but it will be well worth it in the long run. Before you do any breaking in, make sure that it is warmed up first. BTW, doing it on the stand is a no-no and there has to be a load on the engine.

Wow... this is great!
I'll be picking up my Xpeed 250i from the dealer 57 miles from me.
I was afraid that the long maiden voyage would not be good but I'm getting the impression that it would be a great opportunity to do some breaking-in.
One thing though... the scoot says 35 miles on the odometer. I assumed that it's normal for a vehicle to have a few miles on it during building and prepping and such. I also assume it's been taken out on test-drives.
I'm reading that the first few miles should be "hard breaking" miles. How does this affect the break-in?

Well if its a 150i would ride it like i stole it, If it blows up that just means you need to install a BB kit lol

Sorry, but the hard break-in won't work now as well. It has to be within the first 20 miles preferably at 0 miles starting. By trying to hard break it in now won't really do much as it's already been ridden 35 mles. That doesn't mean you can't do it, but the desired results of a hard break-in won't be the same in my opinion. Just make sure to keep varying your speeds and change that oil as soon as you get it home.
On the other hand, if it was a test demo scoot, then you can bet the hard break-in was already done by the testers. Hopefully they allowed it warm up a bit first though.

did the hard break-in on mine as dictated by Motoman. No problems after 4000kms. Miles of smiles.

Am I going to run into problems down the line? How do I do a "break-in" now, after it has been run? I called the dealer and he said that the miles come from when they receive the bikes. They take them apart, and put them back together, change all the fluids, etc. He said they run them after every phase of preparation to make sure all is ok after tightening up all the nuts and bolts and such. Plus, it comes with a 3 year warranty from United Motors. So do I have a chance of properly breaking-in my scooter? It's a UM Xpeed 250i. I just want to make sure I'm doing the right thing. |

there are many opinions on hard vs soft and me being a mechanic chooses the hard way. I did the hard break-in via the fast, then let coast down all the way up to 100 miles and it was quite tedious and boring, I also changed the oil at 0, 20, 50 and 100 miles while doing so. 35 miles isn't bad and I doubt they put them on by "making sure everything is ok." You can bet it was test driven or used as a loaner/demo with that many on it and I'd say they were hard miles too. My SYM came with 1 mile on it and the Xingyue came with 4km's on it so I don't buy that 35 miles to test things theory. In all honesty, the break in is mostly done but I'd continue to do so up to 100 miles the hard way.
