If you want to know how often to service a Honda Grom, the honda grom maintenance intervals are the place to start, but the published numbers are limited. The one hard figure is the air filter, rated for 10,000 miles in normal riding conditions. Honda also says the Grom has low operating and maintenance costs. For oil, valves, brakes and other items, the material gives no interval, so you will need the owner’s manual for your model year.
Honda Grom Maintenance Intervals: What Needs Attention and When
The Grom is a small machine with a simple service list. It has a 124cc two-valve, overhead-cam, air-cooled engine with a 10:1 compression ratio. The oil filter is replaceable, and Honda highlights that owners who do their own maintenance can change it.
Only one service item in the source material carries a stated life. That is the panel-type wet-paper air filter, which lasts 10,000 miles in normal riding conditions. Treat that number as the baseline, not a promise for every ride.
When to Do It: Service Schedule by Component
The table below lists each component, the published detail, and what it means for your maintenance planning. Where the material gives no interval, the table says so instead of guessing.
| Component | Published detail | What it means for you |
|---|---|---|
| Engine | 124cc, 10:1 compression | Another spec sheet lists 123.9cc and 10.0:1, so confirm the figures in your manual. |
| Air filter | Panel type, 10,000-mile life | This is the only published interval. Inspect and replace on that mileage in normal riding. |
| Oil filter | Replaceable by owners | No interval is given. Follow the manual. |
| Front fork | No adjustable preload or rebound damping | There are no suspension settings to log at service. |
| Rear shock | No adjustable preload or rebound damping | Nothing to adjust or record here. |
| Front brake | Dual-piston caliper, 220mm rotor; 2-piston caliper, 220mm disc | Pad and fluid intervals are not published. Inspect at each service. |
| Front brake, standard and SP | Same caliper and disc, without ABS | Your maintenance is the same whether you choose ABS or not. |
| Rear brake | Single-piston caliper, 190mm rotor; 1-piston, 190mm disc | Inspect with the front brake. No interval is listed. |
Those brake rows matter most because the source gives no pad or fluid schedule. Check the pads and the fluid level at every service, and follow the manual for replacement. The rear caliper is a single-piston design with a 190mm disc, so it is simpler than the front setup.
The two engine figures differ slightly between sources, so use the manual for your exact bike. Neither the fork nor the shock offers adjustable preload or rebound, so you will not have those settings to maintain.
Tools
You do not need a large tool kit for basic jobs. The exhaust downpipe and muffler are two separate parts, which simplifies replacement. That separation means you can deal with the muffler without treating the whole exhaust as one piece, but confirm the procedure in the manual first.
For the oil filter, plan on a filter wrench, a drain pan and the oil spec listed in your manual. Because the filter is replaceable and owners can change it, the job fits a home garage. Keep a log of the date and mileage each time you service the bike, so your intervals stay accurate.
Step by Step: Routine Service Tasks
Check and Replace the Air Filter
- Remove the airbox cover and pull the panel filter. Replace it at 10,000 miles in normal riding.
- Inspect the filter before the mileage limit if you ride in dust. The wet-paper design is rated for normal conditions, so harsher use calls for more frequent checks.
Change the Oil and Oil Filter
- Warm the engine, drain the oil and remove the old filter.
- Install the new filter and fill with the oil grade listed in your manual.
Inspect the Exhaust
- Check the downpipe and muffler for leaks and clamp tightness. They are separate parts.
Use the Dash to Track Miles
- The LCD dash shows a gear-position indicator, speedometer, tachometer, twin trip meters, fuel gauge and clock. Reset a trip meter at each service to count miles between jobs.
Plan Stand Work
- The seat height is a low 30.0 in, which helps when you set the bike on a stand or lift it.
- Honda’s sheets list the ABS version at 231 lb and at 227 lb. Confirm the weight for your version before you lift the bike.
Safety Notes
The ABS version uses an IMU to help prevent front-wheel lockup. Honda describes the front ABS as working through the IMU to keep the rear wheel down during hard braking. ABS is a version option, so check whether your bike has it.
Brake maintenance deserves more attention than the published intervals suggest. The front uses a dual-piston caliper with a 220mm rotor, and the rear uses a single-piston caliper with a 190mm rotor. Inspect both systems at every service and replace worn parts before they wear to the limit.
The Grom carries a transferable one-year limited warranty, with extended coverage available through a HondaCare Protection Plan. Read the plan terms before you assume a repair is covered. For a broader look at costs, see How Much Does the Honda Grom Cost? 2025 Prices.

FAQ
How often should I change the air filter on a Honda Grom?
The panel filter is rated for a 10,000-mile life in normal riding conditions. If you ride on dusty roads, check it sooner. That is a judgment call, not a published interval.
Does the Honda Grom have a replaceable oil filter I can change myself?
Yes. The oil filter is replaceable, and owners who do their own maintenance can change it. The source does not give an oil filter interval, so use the manual for timing.
Does the Honda Grom have adjustable front suspension?
No. The front fork has no adjustable preload or rebound damping. The rear shock has the same limit.
Is the Honda Grom still under warranty after the first year?
The standard coverage is a one-year limited warranty. Extended coverage is available through a HondaCare Protection Plan, so check that plan’s terms if you want coverage beyond the first year.
Bottom Line
The clearest interval in the published material is the air filter at 10,000 miles. Honda describes the Grom’s low operating and maintenance costs, and the model comes in standard, ABS and SP versions. For everything else, use your owner’s manual and keep your own service log.
