2021 Yamaha GPD125-A Nmax 125 ABS 0.1L Petrol · CK21 ADZ

The NMAX 125 is one of the most economical scooters on sale, with Yamaha claiming well over 100 mpg in real-world use. Expect to cover roughly 150-180 miles from a tank, making it ideal for urban commuting. Road tax is minimal for a 125cc Euro 5 machine, and insurance sits in a low group (typically group 1-2), so premiums for an experienced rider should be modest.

Annual servicing at an independent motorcycle shop typically costs £120-£180 for an oil and filter change, rising to £250-£350 if you include a brake fluid refresh or air filter. A drive belt and roller replacement is usually due every 12,000-15,000 miles and costs around £150-£250 including labour. Tyres are modestly priced, with both wheels usually coming in under £200 fitted.

Based on moderate mileage, fuel, tax, insurance and routine maintenance, expect to budget roughly £600-£900 per year in total running costs. This makes the NMAX 125 one of the cheapest-to-run vehicles on UK roads.

With a clean MOT record across all three tests and no advisories or failures logged, there is nothing specific to flag from the test data itself. However, you should still carry out a thorough physical inspection because MOT records only cover roadworthiness items at the time of test, not general condition. Given the unusually high mileage accumulated between January 2025 and February 2026, pay particular attention to wear items.

Inspect the front brake discs and pads — heavy commuting use can wear these faster than expected, and replacement discs alone are typically £60-£90 per side. Check the rear brake shoes, the condition of the tyres (look for uneven wear, which can indicate alignment or suspension issues), and the throttle cable for fraying. Examine the centre stand springs and side stand for wear, as these are commonly bent or damaged on scooters used for courier work.

Finally, listen for any rattle from the variator area at idle, check for oil leaks around the engine cases, and confirm the LCD dash functions correctly with no flickering segments. The NMAX 125 is generally reliable, but early signs of drive-face wear or water ingress into the dash are worth checking before purchase.
