Triumph 400-series bike engine broke down; service initially said warranty would cover the repair, then rejected the claim after finding the oil change was delayed by two months. The stated fault was a loose tensioner, and the centre offered only one part covered while leaving the owner with about ₹35,000 remaining cost.
