According to the service manual the 163cc LIKE200i makes just under 11HP at a max engine speed of 7500RPM.
One of the reasons that I change the oil in my 2012 LIKE200i so often is because I regularly see 7000+RPM from my aircooled engine on my rides - and I'm never going much more than about 45 mph (actual)
Today I parked and saw that I had reached 7,280 RPM on my tach....which must have been on the uphill 40mph climb.
At less than a Qt. of good oil, 600-800 mile oil changes are not a deal-breaker for me. On a Burgman 400, 7500 RPM would equal 75+ mph.
On a down hill section of highway the LIKE engine will probably get to 8000+ rpms.
Of course, the figures which I am getting may be related to the Dr Pulley sliders I installed thousands of miles ago. I do remember that I quickly went to heavier sliders because I did not like the increased rpms at low ground speeds from the first set. (people do that to get better acceleration. higher rpms = +acceleration)
I was after the "incredible smoothness" that come from Dr Pulley sliders according to several members, not more acceleration. My drive train is very smooth - no clutch chatter or engine vibes bothering the ride, while the acceleration is perfectly adequate for me - one who does not stress the drive train of any vehicle.
