The Bajaj Pulsar N160 and NS160 are both the same displacement but different engine architecture. The NS160 has a more traditional air cooled unit while the N160 uses a new air oil cooled engine. The result has been much discussion and debate among riders regarding the real world performance differences. Every aspect from low end torque, mid range punch, top end performance, fuel efficiency, to engine heat management in different riding conditions are points of contention. There are those who say the N160's newer engine design gives it a bit of an edge, and then there are those who say the NS160's tried and tested motor is more reliable and fun. Often, the discussion extends to how these engines hold up in city traffic, highway cruising and some spirited riding on twisty roads.
