I Bought my CBZ Xtreme on 2012 and have to say so far so good with millage and comfort. My bike gives a solid millage of around 50 kmpl on any road. Its suspension is the only minus i’ll say about the bike. I would like to say about the solid body make of the bike even thought I had a few accidents the bike damage is very minimal like scratches and broken mirror.
After two years of riding my tiers still gives a solid grip to me on even slippery roads. I say Go for the Xtreme . to ride Xtreme.
