interesting , however a bit hard to do on the real world.
I try to check the tyres, oil, chain every 2 weeks, but really i do when i feel there is something wrong.
You get used to the feel of the bike and if something goes, you notice.
The lights and brake light almost daily, i can see the reflection on the door when i park, heheh
The other points i have a good look when i clean and lube the bike, at least once a month. I like the bike clean.
Anyway i guess it depends on how much your ride , bike age and how you take care of your bike.............
