Hi people, i decided to get a CBR 250RR as my first learner bike. I asked my friends about their opinions and they said i should get a bike that is less than 20k km on the odometer. However my budget is limited to 5k so i could only find some 1991,1992 model CBR 250RR with about 40k km on the odometer. To me, i think my friends are right in some way... Am i going to have a bit of trouble with a 40k km cbr? like maintenance cost....?
