Honda SP 125 Mileage

Launched in November 2019, the Honda SP 125 quickly became a popular choice among Indian commuters due to its stylish design, smooth performance, and fuel efficiency. On average, Honda SP 125 mileage is around 65 km/l; however, real-time mileage may differ for different variants across different users. Why is the mileage of the Honda SP 125 important, and how to calculate it? To get the answers to these questions, stick till the end.

The Honda SP 125 stands out with its premium styling, digital instrument cluster, silent start with ACG motor, and fuel-injected BS6 engine. It’s packed with practical features like an engine start/stop switch, real-time mileage display, and eco-indicator, enhancing the everyday ride experience. The bike is also known for its refined engine performance and smooth gear shifts, making it a favourite among daily commuters. The SP in its name stands for “Smart Power,” reflecting Honda’s intent to combine efficiency with technology, and so is seen in the mileage of the Honda SP 125.

Even though the ARAI-certified mileage for Honda SP 125 is the same across all variants (65 km/l), the real mileage of Honda SP 125 variants may differ, depending on the riding conditions like traffic, type of petrol used, bike’s condition and maintenance, etc. Here’s a mileage comparison table for the Honda SP 125 across its available variants:

Note:

• ARAI mileage is tested under ideal conditions and may vary in real-world usage.
• User-reported mileage depends on riding habits, road conditions, and maintenance.

Checking the mileage of Honda SP 125 is crucial for fuel calculation, understanding the total running cost of the bike and checking if there are any damages or hindrances to the mileage of Honda SP 125. Here’s how you can check Honda SP 125 mileage:

Method 1: Digital Trip Meter + Fuel Injection Sync

Step 1: Use the Mode/Set button on the SP 125’s digital console to toggle to Trip A.

Step 2: Reset Trip A (long-press the button) before heading to the fuel station.

Step 3: Fill exactly 1 litre of petrol. Due to SP 125’s fuel-injection system, it delivers consistent combustion - giving you accurate mileage in smaller volumes.

Step 4: Ride under mixed conditions (city + open road) and monitor the trip meter as the fuel burns.

Step 5: When the engine starts to sputter slightly or nears reserve, stop and record the trip reading. That’s your mileage.

NOTE: SP 125’s precision FI system ensures that mileage measured, even with 1 litre, is realistic and not erratic like older carburetted bikes.

Method 2: Eco Indicator Assisted Mileage Test

Step 1: On the digital dash, look for the green ECO light — it glows only when you're riding economically.

Step 2: After resetting Trip B, maintain a ride style that keeps the ECO light on continuously (avoid hard acceleration and sudden braking).

Step 3: Ride for 50–60 km this way, using consistent throttle.

Step 4: Use the fuel fill data or track the exact petrol used via a measuring bottle for even better accuracy.

Step 5: Divide kilometres covered (Trip B) by litres consumed to get a hyper-mileage number.

Method 3: Full Tank Calibration Using Digital Odometer

Step 1: Fill the tank completely (until auto cut-off). Record the initial odometer reading.

Step 2: Ride normally for a few days. Thanks to the SP 125’s refined HET engine, you’ll get smooth and predictable fuel use.

Step 3: When the fuel gauge drops to the last bar, refill fully at the same pump and dispenser.

Step 4: Record the odometer reading again and subtract the initial reading to get the distance covered.

Step 5: Divide that distance by litres filled to know the actual mileage under day-to-day conditions.

Honda SP 125 mileage is required for calculating the total running cost of the bike and the fuel cost it requires. A formula is used for calculating the fuel cost of the Honda SP 125, which uses the fuel price, the petrol mileage of the SP 125 and the distance travelled. Let us understand this with an example:

• Tinku uses his Honda SP 125 for travelling to the office every day. He travels 10 km to the office and home 7 days a week. He wishes to budget for his monthly expenses, and for that, he requires his petrol usage on the bike. To calculate that, he uses the following formula:
• Fuel Cost = (Distance to be travelled ÷ Mileage) × Fuel Price per litre
• Fuel Cost = (300/65) * 103
• Total Distance Travelled = 30 days of work × 10 km daily
• Mileage = 65 km/l
• Fuel Price = 103 average petrol price
• Fuel cost = ₹475 (approximately)

In this way, Tinku adjusted his monthly balance and kept ₹475 for fuel expenses for his Honda SP 125 bike.

To improve the mileage of the Honda SP 125, you can follow these simple tips and tricks:

• Use the Eco Indicator Smartly

The SP 125’s digital console includes a green Eco indicator light that glows when you ride efficiently. Always maintain throttle input that keeps this light ON for longer durations to maximise fuel economy.

• Maintain Tyre Pressure as per SP 125 Specs

Keep front and rear tyre pressures at Honda-recommended levels (typically around 25 psi front, 33 psi rear). The low weight and HET engine synergy suffer even with minor pressure drops.

• Optimise Gear Shifts

The 5-speed gearbox is tuned for city and semi-urban use. Shift gears at around 4,000–5,000 RPM for smooth acceleration. Don’t stretch the revs — SP 125 performs best in mid-range torque.

• Rely on Fuel Injection, Avoid Over-Throttling

Since SP 125 uses programmed fuel injection (PGM-FI), rapid throttle inputs don't inject more fuel like carburetted bikes, but can still upset efficiency if done repeatedly.

• Switch Off at Long Signals

Thanks to the SP 125’s silent-start ACG starter motor, switching the engine OFF during red signals (over 30 seconds) and restarting doesn't harm the starter — and helps save fuel.

• Use Honda-Recommended Engine Oil Grade

Stick to 10W30 engine oil as advised in the manual. Thicker or non-recommended grades reduce engine efficiency and strain the HET system.

Pay-as-you-drive bike insurance for the Honda SP 125 uses the mileage (total distance covered) of SP 125 to calculate the premium price. Here, the mileage of the Honda SP 125 directly affects the bike insurance premiums, categorising the driver as a high-risk or low-risk profile. Here’s how bike insurance is affected by SP 125 mileage:

• Premium is calculated based on SP 125 mileage

If the distance travelled is high, then the insurance price will be higher as the rider is more likely to be at risk of accidents or mishaps; on the other hand, low mileage riders have a low risk profile, gaining discounts and lower premium rates.

• Mileage is calculated through the Odometer

The total distance travelled or mileage of SP 125 is calculated by the insurer through the odometer, in order to price the bike insurance premium for the policyholder.

• Application-based tracking

Some insurers track the mileage of the SP 125 using a dedicated application for bike insurance premium calculation of the Honda SP 125.

Honda SP 125 mileage has more than one use: to calculate fuel costs, understand the complete running cost of the bike, and check if there are any hindrances with the bike that are obstructing optimal usage of the bike. Hence, it is important to have regular mileage checks of Honda SP 125 bikes. Also, make sure your bike insurance is up to date – to ensure legal and financial safety. Enjoy riding!
