Seriously, couldn't they just extend the tube a bit so it overhangs the exhaust pipe???

This is super common with motorcycles. The motor should be warm, but not ignite-the-oil hot during an oil change. Clean it up with some brake cleaner.

Use a piece of aluminum foil to make a little drain to direct the oil over the exhaust.

I know that's a solution, but as a solution to bad design it's a little bit "Just wear a rubber glove to stop your oven electrocuting you". Yeah sure, but maybe design it better?

Do you have any idea how much the manufacturer saved in not extending the pipe tho?

Because I have no clue. Probably wurf rite

What they actually probably saved was needing to design a whole separate engine case for each bike in their lineup to match all their exhaust configurations.

The idea of having a little pipe protruding out is a different kind of bad design. Things that poke out from engine cases tend to snag or get punched in during a crash, turning what would be some scrapes on the block into a completely totaled engine.

A genuine question if you would like please, I know you meant warm oil for easy maneuvering (oil moves faster when warm/hot), but what about hot oil? Is it safe to change motorcycle oil after an hour or more ride when the oil might be toi hot?

A co-worker of mine tried adding water to his car reservoir after he just stopped from a long ride, the water was near boiling point and it blowed up on him the moment he opened tha water reservoir (not sure that is the correct name). Can such a thing happens with oil exchange?

Oil doesn't expand and steam like water, so no that won't happen, but hot oil leads to very nasty burns and can melt gloves onto your hands. Most bikes run the oil around 200 degrees. So no it isn't safe to change hot oil. Don't do that.

No, you should just idle the bike until the temp gauge comes up. Should definitely not be after a long ride.

Foil is a great idea, I'll use that next time.
