I bought CBZ extreme KS&ES 2 weeks before. I have completed 400KMs, I have never ride above 50km speed( Due to New bike am controlling myself when other bikes crossing me). it gives 45kmpl in city and 60kmpl in highways.
PROS:-
1) Really So smooth when we ride in Highways, some more moderate Roads.
2) No sounds coming from Engine, it having so smooth engine
3) If you ride between 40-50km speed, it will give 45kmpl in City and 55kmpl in Highways
CONS:-
CBZ Extreme KS&ES having only disadvantages is BAd Rear Schockobsers( This prob resolved in CBZ xtreme 2011), you will get back pain if you ride in Bad condition Roads.
Conclusion:- Who are all want to buy bike with very smooth Riding Forever(without back pain) and with 3yrs warantee( in my research no bike having warantee in india) Please go for New CBZ Extreme 2011 with GRS Suspension.
