Hot sizzling comparo between pulsar 180 DTSI and karizma. chck out  

The Karizma is one of a kind from Hero Honda. No other bike from Hero Honda features the fixed fairing combination that leaves the handle bar and forks free to turn within the gap in the panels housing the fairing, headlamps and instrument cluster. The large headlamps and elongated body panels may be a bit distracting and will take some getting used to. But in terms of performance and effectiveness it will be no different from the other bikes. In fact, the large 35/35W halogen headlamp (same as in the Pulsar) in the Karizma will perform just as good as other bikes under night riding conditions, with only a small blind spot on either side past the headlamp beam.

The Karizma is a big bike with unique looks. The sculpted body panels and the classy, chrome-plated exhaust pipe give it a much larger look. It also features diecast wheels and quit powerful engine as tht of the Pulsar 180(matches 180 due to DTSI technology inspite of being 225). Despite the points in favour of the Karizma, the biggest difference between this bike and the Pulsar is really only its looks. A comparison of the other performance parameters between the Karizma and the Pulsar 180 DTSi comes up with little that is dramatically different between the two. The Karizma's engine is nearly 45 cc bigger than the Pulsar 180 DTSi's but is only about one bhp more in terms of peak power. Both the bikes have design themes that may be appealing to different buyers. Build quality and maintenance costs will be similar. So, the decision really depends on our likes and dislikes. The Karizma may still be a better choice given its unique design and the bike is also currently available at a lowered price.

i still say both stand on diff corners with respect to their configuration. so finally it depends upon taste of an indivisual. still my opinion 180 DTSI!!!!!!!!!
