Hero currently lists the Impulse in the available bikes but most of the above 125 cc bikes of Hero (Impulse, Achiever, Karizma R and ZMR) are not being produced as their already made units are selling at a very low speed. Hero's next update on their website will surely end this confusion and they may delete the bikes which have been discontinued or not being carried forward to the next generation. Impulse is a nice bike with good power to weight ratio and an excellent India friendly ground clearance. The lesser popular dirt bike design of the Impulse lead to its limited approach among the 150 cc bike buyers. You can easily get one from a Hero dealership on order.
