This topic (but not this specific question) has been beaten to death on moto forums, so I don't dare ask it there, but it's probably safe here:
I don't have one yet, but hopefully in the near future I will be purchasing a new motorcycle to replace the Ninja 300 I bought used as a newbie's bike. For that last 6 months or so the Yamaha XSR900 has been at the top of my list of options.
Regarding engine break-in, the XSR900 owner's manual says what you see in the quote below.
>>>> In this context, what do you think the term "prolonged operation" means? <<<<
More than 5 seconds? 10 seconds? 30 seconds? 1 minute? 5 minutes? (red line is 11250 rpm)
I have no way of knowing what they're thinking. Do you?
TIA
0-1000 km Avoid prolonged operation above 5600 rpm
1000 km Change oil and filter
1000-1600 km Avoid prolonged operation above 6800 rpm
> 1600 km Knock yourself out. (my words)
