Motogadget products are, in our experience, among the finest quality motorcycle components we've laid hands on. That said, on a rare occasion we might see a bad m-unit, m-Lock or LED light but it's limited to a couple a year at most. If you're having issues the first course of action is to follow the troubleshooting guides included in their manuals and refer to the more in depth guides we've created.
If you've exhausted all of your options and are convinced you have a bad component Motogadget warranties their products for one year from the date of purchase. If you have a bad Motogadget product that is under warranty and requires replacement it must be returned directly to Motogadget for exchange, their dealers and distributor no longer handle warranty exchanges or returns.
