Hi guys,
I have a question about the break in period on a new bike. My manual just says to avoid the high RPMs for the first 300 miles.
Is there anything else I should be doing or not be doing during the break in period?

Thanks,
Justin

 

Well, parts are machined within specific tolerances. So breaking-in gives moving parts the time required to "rub away" machining inconsistencies that fall within a given range of tolerance so they can form a more custom fit to one another. If the manufacturer recommends moderate rpms for the first 300 miles, you should probably prepare to change your oil after that mileage interval so you can remove all of the metal shavings and filings from the engine. Other than those two things, you should be in the free and clear as far as babying it goes. Proper break-in has a huge effect on the over all life expectancy of the engine. You may want to have that first oil change done at a shop as opposed to doing it yourself so you can save the work order as proof of proper break-in. This could be a valuable bargaining chip should you decide to sell the bike in the future.

 

The avoid high rpm's is for sustained periods of time. It won't hurt to occasionally
blip the throttle. You should, actually, avoid maintaining any specific rpm for long
periods of time. Or that's what I've always been told. I.e. don't drone along at exactly
40 mph, gradually roll up and down on the speed, around your target goal.

After the break-in be sure to change the oil AND filter to eliminate the flash wear
from parts seating in.

Hope this helps, Ern

 

This is probably controversal to say but they way they build new engines today, they don't really 'break in' anymore. Back in the day there was a whole 'process' to break in an engine properly.

The 300 mile period is really just a shake down period.

Follow the suggested guidelines and after the 300 , bring it back to the dealer for the 300 mile check up and your good to go.
