The full motorcycle service checklist

A complete motorcycle service touches five systems: engine (oil, filter, plugs, valves on their schedule), drive (chain and sprockets), brakes (pads, discs, fluid), wheels (tyres, bearings, pressures), and chassis (cables, pivots, lights, battery). Work through all five and nothing on the bike is quietly going overdue. Skip one, and that is usually where the next fault comes from.

The checklist

For most road bikes the rhythm runs: oil every 6,000–12,000 km (4,000–7,500 miles) or yearly, valve clearances every 24,000–40,000 km (15,000–25,000 miles), chain lube every 500–1,000 km (300–600 miles), and everything else in between. The table carries the schedule-driven items; intervals are typical for modern road bikes, and your manual narrows each range to one number — the manual wins. Every interval is distance or time, whichever comes first: service intervals explained covers why a low-mileage bike still needs the calendar half.

Item	What to do	Typical interval
Engine oil and filter	Drain warm, new filter and crush washer, refill to the mark	6,000–12,000 km or 12 months
Air filter	Paper: replace. Foam or gauze: clean and re-oil	15,000–20,000 km, sooner in dust
Spark plugs	Replace nickel plugs; iridium last far longer	10,000–15,000 km
Valve clearances	Measure cold, adjust if out of spec	24,000–40,000 km
Chain and sprockets	Clean, lube, set slack, check wear	Lube every 500–1,000 km; check monthly
Brake pads and discs	Measure pad material and disc thickness	Check monthly; pads out below 2 mm
Brake fluid	Replace with fresh fluid of the specified DOT grade	Every 2 years regardless of mileage
Tyres and wheel bearings	Pressures cold, tread depth, age, bearing play	Pressures weekly; the rest each tyre change

The chassis items are missing from the table because they are condition checks rather than intervals — do them at every service, since together they take minutes. Lube and inspect the clutch and throttle cables and set their free play. Grease the lever and side-stand pivots. Test every light and the horn. Check battery voltage: 12.7 V or better rested is healthy. Run a hand over the fasteners you can reach; anything loose gets torqued to spec, not guessed tight.

Minor vs major: what shops mean

A minor service is the oil service plus the inspection round: oil and filter changed, then chain, brakes, pressures, cables, and lights checked and adjusted. It lands annually or every 6,000–12,000 km. A major service is all of that plus the long-interval and calendar items as they come due: plugs, air filter, valve clearances, brake fluid, coolant. That is why the prices sit so far apart — $100–250 (€90–240) for a minor against $400–800 (€370–740) for a major, with the valve check carrying most of the labour.

The word service is not a standard unit. When booking, ask which items are actually on the sheet. When comparing quotes, compare the item lists, not the totals — a cheap major that skips the valves is a minor with a markup.

A home service day, in order

The order exists so nothing gets done twice:

1. Warm the engine for a few minutes, then drain the oil — warm oil carries the contaminants out with it.
2. While it drains, do the wheel end: tyre pressures and tread, pad thickness, and a bearing rock test with each wheel off the ground.
3. Fit the new filter and crush washer, refill, and leave the final level check until after the test run. How to change motorcycle oil covers the torque discipline that keeps drain plugs alive.
4. Plugs and air filter if they are due — often tank-off jobs, so batch them together.
5. The chassis pass: cables, pivots, lights, battery voltage, fastener once-over.
6. The chain last — clean, lube, set slack — after any wheel work, so you set the alignment once and leave it alone.
7. A short test ride, then re-check oil level and chain slack.

Two practical notes. Order the parts a week ahead — filter, crush washer, plugs if due — so the day is not lost to a parts run. And drain the old oil into a sealed container for the recycling point or an auto parts store; it is the one waste product of the day that cannot go in the bin.

First time through, expect 3–4 hours. Once familiar, about half that. The honest exception is the valve check: on screw-adjuster engines it is a patient afternoon, on shim-under-bucket engines it is cams-out work that most riders hand to a shop — valve clearance explained makes the case either way, and skipping it is the one economy that eats engines.

The record is half the service

A service that nobody wrote down has a half-life of about six months in memory. Every item you touch gets a line: date, odometer, what was done, what it cost — how to keep a maintenance log covers the format that makes the file useful. The next service starts from that record instead of from guesswork, and the same file becomes evidence of care when the bike is eventually sold.

Between services, the two-minute pre-ride check covers the gap — tyres, controls, lights, chain, leaks. The full checklist keeps the bike sound; the short one catches what changes in between. Run both on their own schedules and the bike stops producing surprises.
