Cheapest to buy is not always cheapest to keep
Across the 6 motorcycles in this guide, the estimated monthly running cost spans about ₱2,632 to ₱5,038 — a difference of roughly ₱2,405 a month, or ₱28,860 over a year. On a five-year ownership horizon that gap matters more than most buyers expect when they are comparing showroom prices.
In this particular guide the cheapest motorcycle to buy is also the cheapest to run, which is not always the case — heavier or larger-displacement models often reverse that once fuel and consumables are counted.
Fuel is the part riders feel first, but it is rarely the biggest line. For the Suzuki Gixxer SF 155, the estimate splits roughly into ₱1,165 of fuel, ₱650 of routine maintenance and ₱817 of insurance, registration and tyre reserve spread across the month.
On that basis, budget somewhere between ₱31,584 and ₱60,450 for a first year of running costs, before financing. If you are buying on installment, add the monthly amortisation on top — that is a separate number, and the two together are what your actual budget has to absorb.
