Has anyone done this? I’m about to wash out my airbox (have a wash cover) !and would like to remove the seat and lightly spray also (battery wiring etc).

Before you all accuse me of being a complete idiot there are a multitude of electrical connectors behind the front number plate that get sprayed indirectly with no ill effects when we wash our KTM’s.

Anyone ever done this with good/bad outcome?

Don’t unless you want possible electrical problems , just use a rag and windex or other type of cleaner for where the battery is ...

Don’t pressure wash the electrics. Just wipe down with damp towel.

Remove the air box and wash it by hand if you really need to.

Pressure wash no. Lightly spray with hose and wipe yes. I remove the seat every wash but i dont use a pressure washer. Never had an issue.

I wash mine out, with pressure washer all the time. Suzuki, Honda, Yamaha and KTM’s. I’ve never had a single problem.

I wash this area with my power washer all the time. No direct hit, but yes with the power washer.

I use this on all my electrical connections.

Dielectric grease is electrically insulating and does not break down when high voltage is applied. It is often applied to electrical connectors, particularly those containing rubber gaskets, as a means of lubricating and sealing rubber portions of the connector without arcing.

I had a 16 KTM 350 that I liked keeping clean. Didn't even wash with the seat off and it developed electrical gremlins. You've been warned. smile

Skip it bro, hand wipe carefully, I have the 18’ FC450, And believe me the pressure washer thought crossed my mind. Didn’t do it though.

I couldn't resist...wrapped plastic around and taped up the electrical connections, lightly sprayed it with the pressure washer and blew it all off with air. Bike started right up after.

I won't make a habit of this but it seemed to turn out ok.

I wash my 2018 350SXF with the seat off all the time. Never have an issue.

Soap and a hose. I never power was my bike unless it was a real mudder which is very rare.

The only electrical issue I've ever had is the fact that the ground wire for the battery is held on by a bolt that also holds the rear fender on. That bolt came loose and was causing an intermittent no start issue. I wouldn't relate that to washing it at all tho.
