i´ve been having a karizma for over 6 months now . we race it on the chennai race track every weekend and commute 60 km everyday . on track it gives me 30 and normal cruising it gives me 40 kmph -- the secret ,,, perfect running in . the karizma is a highly detuned bike , my friend has made it produce 22 BHP by justa few mods on the head . just ensure u dont rip a new bike and never exceed 4500 rpm for the first 2000 kms ( its easier said than done) and the bike will give u great performance . the engine should be good for atleast 30000 kms
