Bike intervals are shorter than car habits

A motorcycle engine works harder per mile than a car engine, and the maintenance schedule reflects it: oil changes commonly land at 3,000–6,000 miles, chain lube every 300–600 miles, brake fluid every two years, and a valve clearance inspection at whatever interval your manual sets — often 15,000–26,000 miles depending on the engine. Rain riding, short trips, and track days all shorten these further.

Because the intervals are short and mixed (some by mileage, some by calendar), memory fails faster on a bike than on a car. Write the odometer into every entry and set the next due point the moment a service is finished.

Log the chain like the consumable it is

The chain is the highest-frequency item on the bike, and its log is more useful than it looks. Record the slack measurement every time you adjust it: when adjustments start coming closer together, the chain is stretching toward replacement, and the log shows you that trend before a worn chain takes the sprockets with it.

At each cleaning, glance at the sprocket teeth and note their condition — a quick photo in the entry is enough. Chain, sprockets, and the mileage they were replaced at together form one of the first questions any knowledgeable buyer will ask.

Valve clearance records are resale gold

A valve clearance inspection is expensive, invisible from the outside, and skipped by a large share of owners. A log entry with the date, mileage, and the actual measured clearances is proof the engine has been maintained beyond oil changes — it is one of the strongest single records a used bike can carry.

The same applies to fork oil, coolant, and brake fluid: cheap services that are impossible to verify by looking. On a motorcycle, the log is not a summary of the bike's condition; for these items it is the only evidence that exists.

One log per bike, kept on your phone

Paper logs do not survive garages, and spreadsheets are painful to update with gloves half-off. A vehicle log app keeps each bike's history separate, attaches the receipt and the sprocket photo to the entry, and turns the next-due mileage into a reminder. GarageLog handles motorcycles the same way it handles cars and is free to start.

When you sell, the whole history becomes a shareable page instead of a shoebox. The format is identical to the shared car-history example linked below — every entry dated, mileage attached, evidence behind it — and it answers a buyer's questions before they are asked.
