WOW i broke it til 1,000 km but i guess you guys are talking miles. I kept it below 7 ish but varied the range. I have 3500km on it and still find that the speed keeps getting a litter higher and the rpms keep gettin a little lower. But I could be wrong. -i
I broke my F4i in hard, not according to the manual. I've thrown over 10,000 miles on my bike and I haven't had a problem yet. Basically, I stretched the entire rev range of each of the gears while staying above 4,000 RPM. I also avoided constant speed for the first few hundred miles and changed the oil every 200 miles for the first 600 miles.
