boys you will not believe this but i did 80km/ltr on long route straight road on honda cd 100 2011 model,u can achive this on mostly constant speed and if it is drived on speed on above 50 till80.but on regular ride it is upto 55km/ltr.earlier there was a problem with starting i.e, missing but if warm it up for 10 min before travelling it will never bother you with missing problem. i recently ride to khunjerab pass pak-china border i travelled 1500km in total fuel of Rs.2500/- for long rout ride its the best.
