V4 Tool Bag Tray Full Of Water - Drill Drain Hole?

Discussion in 'Multistrada' started by baines93, Feb 18, 2026 at 2:47 PM.

  1. Hi all. Does anyone else find their tool bag / puncture repair kit under the pillion seat is often sat in water? Especially after I wash or hose down the bike, water pools in there. As per this post...

    Given most of the time it's on the side stand, thinking about drilling a small hole in the forward left corner to drain, but I think there's a void between this panel, and the plastic undertray above the wheel/rear hugger, so not exactly sure what it would be draining into... although i'm sure it would find it's way out. Does mean road spray is unlikely to get in through said hole...

    Has anyone else got this issue? Or done this?

  2. I had this with a car a while back. I drilled a hole wide enough to accommodate some fish tank air line and pushed that through with some silicone to seal. Ran the line away from car boot and it worked a treat. Worth a shot?

  3. Similar on a different bike.
    Making a small hole and inserting a small length of rigid pipe and glued it into place.
    When the glue was set and the pipe solid I attached a length of flexible pipe to it and ran it down alongside other wires/pipes so it could discharge away from the bike.
    Worked well, although really it’s an oversight on the manufacture behalf.
     
  4. My toolkit was rusted quite badly when I got my bike at 21k miles. I didn't know to look there though.
    A good indication of previous ownership that I'll be checking if/when I buy a second one!

  5. Bike tool kits are usually made by Cadbury's. Take them off store them dry and put them back on for a resale.

  6. In the V4 it’s predominantly the tools, strips and co2 canisters to repair a puncture and reinflate. I carry a rechargeable inflator but I need the rest and it’s a handy place to keep it.
     
  7. Am I the only one that always keeps tools etc on a bike in sealable freezer bags?

    I don't think I've owned any bike where that sort of compartment was truely dry.
    Except maybe my M900 where the compartment was built into the underside of the seat.

  8. @baines93 exactly the same happens with mine too, sometimes the tray gets so full of water it’s almost into the power socket. The puncture repair kit is sodden now. I too should drill a hole so it can flow away. It will eventually find its way out between the 2 plastic trays.

  9. I think I’ll try a little hole in the forward most left corner where it pools on the side stand - and keep the kit in a sandwich bag!
     
  10. Let us know how you get on, please (and where it goes if you just drill a hole and have no tube).
    Thanks!
