When did you service your motorcycle, what did you do, and at what mileage? Motorcycle Maintenance Log helps you record routine inspections and parts replacements, then check when your next service is due. ■ Record maintenance Save each task, such as an oil change or tire inspection, with the date, odometer reading, and a note. You can record one-time jobs as well as recurring maintenance. ■ Check upcoming service by mileage and date Set the next scheduled mileage and date for each maintenance item. Update your odometer reading to see how far away or how soon the service is due. ■ Keep photos and service history Add photos to maintenance items and service records to review parts condition and past work. ■ Set up items with presets When registering a vehicle, choose initial maintenance items for Standard, Harley-Davidson (belt drive), BMW (shaft drive), or Scooter. Maintenance intervals are general guidelines. Adjust them to suit your model, year, and riding conditions. ■ CSV backup for each vehicle Save one vehicle’s information, maintenance items, history, and photos together in a single CSV file. Importing a backup CSV from this app adds the vehicle as a new entry; it does not overwrite existing vehicles. CSV files are for restoring data in this app. Editing and resaving them in spreadsheet software may prevent them from importing correctly. File size and item counts are limited. ■ Free features Use the first vehicle registration, maintenance item and history records, photo records, and upcoming service schedule. ■ Premium (one-time purchase) Hide standard ads and register additional vehicles in your garage. Set service intervals according to your vehicle’s condition and the manufacturer’s recommendations.
