The all new 150cc four valve engine brings some interesting figures to the 150cc class. To start with, it's the first under square engine in the Pulsar line-up, and shares the same 56mm bore as the Discover 150. Its 17PS power output is second only to the 18.5PS CBR150R and equal to the Yamaha R15's.
It also features a four valve head like the Discover engine but that's where the Discover similarities end. It's quite refined in terms of vibrations though the thrashy engine note betrays its air cooled single layout. The vibes are only really noticeable through the foot pegs when the tachometer needle nears redline. Power delivery is smooth too and fairly linear with a slight surge upwards of 7, 000prm up till the rev limiter. Strangely, the characteristic long stroke mid range punch is missing and the AS likes to be revved to get a move on. It doesn't hinder the riding experience though and there is enough torque in the motor so you're not manically shifting up and down the box in town. There is some sponginess in the gear shift linkage though that makes gear changes soft and not crisp, as they should be. In our acceleration runs, the AS crossed the 100kmph mark in 21.85s and went on to a top speed over 125kmph. It's quite efficient too, returning a very respectable 52.8kmpl in our combined city and highway run.
