Pulsar SS400 would most probably be called as Pulsar RS400 and the news of it being spotted testing in the production version had came a long time back. The motorcycle must be ready but Bajaj Auto has not decided any of the launch date currently. It will be using the KTM RC 390's engine in a different state of tune while we can expect a 7 second 0-100 kmph sprint from the motorcycle.
It is expected to carry a price tag of around INR 1,75,000 and most probably you will be able to buy the bike in the year 2016 itself.
