Honda CB 125 Hornet mileage and running cost

CB 125 Hornet's claimed mileage is 55 kmpl, and unusually, owners and our own riding land right on it: expect 51–57 kmpl in everyday use. Few bikes get this close to their brochure figure.

Among the 67 sports bikes we have reviewed it ranks 10th for mileage, 13 kmpl above the group average of 42 kmpl.

At Delhi's petrol price of ₹94.80 a litre and a real-world 54 kmpl, the CB 125 Hornet costs about ₹1.76 per km in fuel. Ride 30 km a day and that is roughly ₹1,369 a month, or ₹16,432 a year, before servicing.

The 12-litre tank gives a realistic range of about 648 km, so a 30 km commute means a fill-up every 3 weeks.

Spread over five years and 46,800 km, the CB 125 Hornet works out to about ₹5.3 per km all-in, of which 33% is fuel and 53% is the purchase price itself. Resale value is not counted; expect roughly 50–60% of ex-showroom after five years for a well-kept example.

The quickest wins for the CB 125 Hornet: keep tyres at the recommended pressure (under-inflation by 5 psi can cost 2–3 kmpl), shift up early and avoid idling at long signals.

Short trips hurt most. A cold engine on a 2 km run can return half its normal mileage; if that is your use, expect the low end of the real-world band.

Service on time. A clogged air filter or old spark plug shows up in mileage before it shows up anywhere else.
