Loses out, by an inch, to the competition.

All the tweaking to the engine has left the Boss with an undeniable edge as far as Performance goes but there has been a slight downturn on the Fuel Efficiency front. The best figure the Boss 115 returned was 80kmpl while the worst figure she returned was 52kmpl. On the city test route the Boss returned a figure of 67kmpl.

The 100cc Boss on the other hand returned a best figure of 84kmpl and worst figure of 70kmpl, much better than the new model. The Boss 115 fails to make much of an impression on the competition in this segment all of which manage best mileage figures in the high eighties.
