Best value in each row is marked green. "Not applicable" means the specification does not exist for that bike (an electric bike has no fuel tank); "Not listed" means the manufacturer does not publish it. A dotted underline marks a value published for the model rather than for that variant — where variants are known to differ on a specification, each shows only its own value. Assumes petrol at ₹105/litre and electricity at ₹8/unit; claimed mileage and range, so both sides read optimistic. On the on-road price at 9.5% for 36 months after a 20% down payment.
