I purchased myCBZ Xtreme in 2007, and its been running non stop till date, clocked 60, 000 Kms. Getting an average mileage of 50 kms / Ltr. Very well adapts it self for City and High way driving. The other brands of bike famous in this segment is Pulsar and Apache. I have driven these bikes and after 3 years of continuous driving I find my CBZ to be way more stable, less prone to repairs.
I have done xtreme biking like the Bike drive from Bangalore to Goa than from Goa to Dudh sagar, where you have to some time drive on the Railway tracks. Only the tires have worn out, rest of them look brand new.
Bullets are the ultimate but this is best bike for a typical Indian.
