Cant really say which is better. Some say Cbz is a better handler than the pulsar and along with they say that double down tube is better in handling, so you see the conflict?
Single downtube has the adv of less weight and using the engine as a stressed member gives the weight advantage.
Double cradle chassis gives more rigidity but compromises in weight.
But the anomaly still remains between CBZ and Pulsar.
The doulbe cradle chassis of the RX series has been proved to be one of the best on indian bikes in terms of handling.
Guys what do you think?
