For 2017, Bajaj Auto has updated its entire range of Pulsar motorcycles - with updated engines meeting new Bharat Stage IV emission norms and the automatic headlamp on ( AHO) function. And along with some minor design and new colour variant that too looks good but bajaj bikes has certain disadvantages like new bike will be good as for you ride normal and as well as new engine will be smoother beacause it has 6 speed gear box and 23hp is good .and after 5to6months engine will gives noise and it will not be smoother even if you use high grade engine oils . for 500kms will be good after changing oil and after wards it starts giving noise . so this will be bad . this bike is not stable in high speeds also . mileage wise around 30+ in city and highways 40+ . not bad but disadvantages is engine noise and vibrations .
