Full fresh engine, initial power still as a new one.. break in period maintained from 0km to 2500km. And it gives a great mileage. You'll have 40-42km in the city and 42-45km on the highways. I've gone up to 136kmph without full RPM, and you can go even further. No accidents happened. The bike doesn't have even minor problems. The reason I'm selling this bike is I'm going to abroad and there will be nobody to use it.
