Choosing an Avenger among 150 and 220 depends upon the motorcycling need of a rider. City driving is better with 150 as it consumes less fuel and provides adequate power whereas powerful highway rides are offered with the 220 cc engine of both the 220 Cruise and 220 Street. If you love cruisers and chrome, there is no other choice than 220 Cruise while dark themed Avengers can be selected according to the preference between economy and performance. The best looking shade on the bike is actually the Midnight Blue from 150 Street.
