Yes but most garages/workshops don't have any motorcycles in them!motorcycles do [catch fire]
(thinking back to my fire marshal training … ) I'd say extinguishers aren't a Should or Must in any domestic setting. UNLESS you have risk items, or are doing Risky Things (e.g. with flames ). Another factor would be whether your garage is part of your house i.e. if it's detached then there is much reduced risk to life (of course cherished bicycles also come into this … )
It's illegal to store certain quantities of most flammable liquids etc, so it's just a few people who are legally storing enough flammables to justify an extinguisher. But having one won't do any harm!
