I have been riding CBZ since Nov 2009 and till now great performance!! Flawless pickup great for Redlining! Just take care of the lube & filters and the bike will take care of you!!
For the negative side!, it has body vibrations after 9 months or a year! Gear change too noisy which is common on all Hero Honda bikes. I have been using Synthetic lube Castrol Power 1 Racing! the pickup is enhanced and also got extra drain life of total 5 to 6 k Km use unlike 2k Km in normal mineral oil.
Altogether, I would like to add is it is a great bike and one can blindly opt for one for years of peace & maintenance free biking!
