CBR250R is a great choice for a first timer
and it also depends on how hard u pushing the bike.. As for me my bike is new and in am still breakin in.. 6k RPM @ 100kph.. i am sure others will have a view on this..
Will sit at an indicated 100kph at exactly 6000rpm. A very sweet spot for it to lightly cruise at.
Indicated 110 feels good but it's entering the powerband so it doesn't sit as well there imo, you feel you want to open it up a bit more.
Whenever I'm 2 up with the missus I cruise very happily at 100kph indicated at 6000rpm. It will still get you up to 140kph indicated pretty quickly if you pull back.
On an empty highway I always pin it and cruise at anything between 145-160 indicated depending on wind resistance. It cruises easily when pinned... stable and secure as anything for hours on end with the throttle pinned.
Yes it's 10% for my Australian delivered version. So:
88 km/h indicated=> 80 km/h true (gps)
So now I ride at 88, 99, 110 etc. for respective speed zones...what's the point Mr Honda?
I considered getting one of those electronic pulse frequency modifiers to compensate, but have found that the odometer and trip meter function is accurate as it is. Tinkering for the speedo may very well screw the odometer.
