Little engines - mine too
My bike barely runs below 5500. My ride to work is relatively downhill but even so if I am rumbling along in 6th gear at around 60km/h and about 4000 revs I have to chage down at least two gears before I can open the throttle and get a response. If I do try to make the bike pull below 5000 it chugs and splutters pityfully. Change down to fourth, roll on the throttle and it's all go.
Once the engine is at operating temperature rev it, that's why it has a rev counter and short gearing. It is also much smoother over 6000. At 8000 I can almost see in the mirrors!
I'd be suprised if any 250 single made pulls strongly at such low revs. If you don't like revs make sure you keep away from the smaller Japanese multi cylinder bikes. My CB400SF didn't go at all until about 8000 and pulled happily right up to 14000, all day!
The guys at CSC did over 5000 miles with the original bikes and wrote about it at length - 5000 at 8000 the had no hassles at all. I think the 250 motors will outlive us all.
