1. If it has a steering lock, lock it.
2. Disc lock on front and rear if you have it. Preferably use an alarmed disc lock.
3. Chain it to something
4. Keep it covered
5. Buy an actual motorcycle tracker, cheap ones run like $200. They’ll alert you if there’s movement and if it’s tilted.

Anything small is likely to get stolen. Dirt bikes are gonna get stolen fast. Newer sport bikes are a target but older ones are a little safer. Cruises are probably the hardest to steal since they’re heavier.

Why not just get an electric bike? They’re cheaper than a ruckus and you can bring them inside if you need to.
