I have Suzuki 110 sprinter bike model 2009. As it has just run 49000km up to now, its ring piston have worn out and are needed to be replaced because smoke with Mobil oil comes out from its silencer. I did extra care of bike and never time it happened that I did not change its engine oil within 1100KM then why its ring piston has worn out within 49000KM. If we compare it with Honda, its ring piston runs up to 70000KM. I always use Shell motor bike oil and change the filter after 4000KM also according to the manufacturer’s recommendation. Please share your experience with me as next year I shall change the bike insha-Allah and I had plan to buy again Suzuki but I think I am needed to change my mindset now.
