I have recently serviced my bike by a local mechanic and he changed the engine oil with castrol active 1 Lit engine oil.According to latest news reports, Hero Honda(No.1) and Honda(No.2) are top sellers of two wheelers in India. Bajaj is third and TVS comes fourth. HMSI overtook TVS and Bajaj within few months. Bajaj saga: Bajaj got very good technology, training etc from Kawasaki.Pulsar and CT100 were the fire, I bought my new honda unicorn bike on nov 4th 2006. The bike is really cool. It has a smooth engine, good mileage, good looks and many more. But the worst thing about the bike is its monosuspension. I have crawled the honda website to see the technology behind the monosuspension.
