Got caught in a frakin monsoon yesterday. Calling the bike rinsed.
How waterproof are those electrical connections behind the headlight? There's a pretty big connector there that's just open to sucking up water.
it really depends. they are supposed to be pretty good but you might find some people (ahem) who went behind our fine bolognese engineers and put electric grease into the main ones. i've pretty much gone thru my bike and removed and replaced everything so it wasn't because i was bored one sunday morning. i have just found it good practice to add the grease when you remove a connector.
