Your motorcycle checklist
- Fill the tank and add fuel stabilizer, then ride or idle a few minutes so treated fuel reaches the injectors or carbs.Helpful gear: Fuel stabilizer — Recommended pick
- Change the oil and filter before storage so acids in used oil do not sit on internal parts all winter.
- Put the battery on a tender for the whole layup rather than starting the bike for a few minutes now and then.Helpful gear: Battery tender — Recommended pick
- Set tire pressure to spec and, if you can, lift the wheels with stands so the tires do not flat-spot.Helpful gear: Front paddock stand — Recommended pick
- Lube the chain and wipe down bare metal with a light protectant to fend off corrosion.
- Plug the exhaust and airbox loosely so mice cannot nest, and set traps nearby as a backup.
- Cover the bike with a breathable cover indoors so moisture does not get trapped against the paint.Helpful gear: Breathable motorcycle cover — Recommended pick
- In spring, remove the plugs, check tire pressure and brakes, and reconnect the battery before the first ride.
