I would like to share my experience and opinion about the hero Honda Karizma R which is not at all reliable bike and is very dangerous to ride. My father own a Karizma and I ride it sometimes. According to my experience the most important negative point of this bike is that whenever you apply the rear or front brakes suddenly, the tyres get locked immediately and the bike slips on the road and can cause accidents.
Once I was riding and suddenly a man came in between and I applied the brakes, the Tyres got locked and I was thrown from the bike on the road. The brakes are to much powerful and the bike doesn't have any kind of road grip.
