The heart of the Pulsar 135 is an engineering marvel, the World’s first 4 Valve DTS-i engine, which provides greater power and can be revved to much higher rpms without any engine strain. The bike boasts a power to weight ratio that is higher than some 150cc bikes giving the Pulsar 135LS the ability to go from 0 to 60kmph in 5.1 seconds and a fuel efficiency that is comparable to 125cc bikes, I also bought a pulsar 135 sl I blue its look great with almost or above 55 km .
