What to check on a Ninja 400
- Check both sides for drop damage: levers, bar ends, mirrors, pegs and fairing.
- Check that the shift lever and brake pedal are straight.
- Inspect the chain and sprockets for neglect.
- Confirm whether it has ABS (it affects price and resale).
- Check that aftermarket turn signals or lights work and are wired cleanly.
Do these on top of the standard walkaround. The free kit has the full list.
