Hello all, I purchased KTM Duke *** in the year **** month of December this is the month which was mentioned in the invoice and got rto registration in the month of Feb ****. Coming to the main topic, after my first service there was an oil leakage in the engine head and they said that there is a fault with the rubber which was placed between the head and body part of an engine and later with in * months there is been cranking noise from engine head and they have charged with around **** rupees as there are some things wont cover under warranty. Nearly * times they have opened the main part of a bike which is engine in the time perioud of * and half years. Now in the last month there was some low battery issue in the bike and service adviser replaced the stater coil and charged me around **** rupees. But still the issue showing low battery persists in my bike.
