For the 16V models, but fits also 8V's...homemade mounting bracket.

Slotting the belly pan (on my K75S) into the two rubber grommets at the front end, is incredibly tricky, and after tightening up the bolts once you *think* it's in place, it still wobbles around a bit.   Is there an easy, failsafe way to do this as I'm slightly afraid of it coming lose... at 90mph

Yes, the 2V and 4V BPs are slightly different but can be made to interchange with some DIY effort.

I've owned something like half a dozen K75Ss and as long as you get those two long M6 bolts properly threaded and fairly tight then it won't fall off.  And at 90 MPH there's lots of wind pushing on the front of it to keep it on the mounting brackets.

Good point: I'll just have to ride everywhere at 90mph !  And I guess there is no easy way to slot it into the grommets...?

It's a bit tricky. No way around that.

I wasn't satisfied with how hard it is to do on a K75 so I decided to mount a K75 belly pan on a K100. That one's even harder to get mounted on those grommets and I had to drill new holes in the BP in just the right places to get them to line up to where that lower front bracket gets mounted on the longer engine.

Hello all - I am looking to fit a belly pan for my 1986 K100RS. I know that the belly pan wasn't introduced until later models - 

* Can a belly pan be fitted to a 1986 K100RS?
* Any advice/tips on what to look for when looking for them on eBay?


Many thanks!

Yes. But get the one for the 2V RS, not the 4V RS. They look very similar but are slightly different and mount differently.

Find one with both the mounting bracket and BP if you can.

I have a 16v one with the mounting brackets for sale if anyone needs one.

Hi BobT - what colour is your Belly Pan? How much are you looking for it?

It is black, and want about £70 plus P&P, which will cost a fortune due to the weight of the thing.

Hi - could you send me some pictures of it? I would like to see it if possible - I am based in the UK, would you be able to post it here if a sale was agreed?

I could post it there with no problems. I will be in the UK on the 8th of August for a tour around Devon and Cornwall, but will be on my Ducati Supersport 939, and that has no room for much in the way of luggage.
I'll take some pictures over the weekend.

Okay - brilliant stuff - thank you

Hey - hope you're having a good weekend! How are the pictures coming along? (sorry to chase) - where are you based by the way, trying to figure postage costs!

South of France mate, if you can figure out the postage costs then let me know. I shall have to weigh the pan and mountings, get rough dimensions and then ask at the post office which will be funny. 
You could join the Irish contingent and visit in September and fit it here, talk to Olaf and he will give you the dates.
I'll do the pictures tomorrow afternoon.

Hey BobT - hope you've had a great weekend. I not sure what the costs would be for postage, but recently purchased full K100 panniers from Germany (via eBay) and it was around the £20 mark. I am sure we can figure that out! Any joy with the pictures?

Many thanks!

Hey - hope your week is going well - any updates on that BP? Thank you again!

Love the bike what sort of paint have you used

It's not actually paint, it's Line-X truck bed liner. I use it because it's inexpensive and incredibly durable compared to paint.

Note that you can buy truck bed liner in a rattle spray can at the auto parts store but I've tried it and it doesn't hold up like "real" truck bed liner. The reason is that stuff like Line-X is actually a two part material similar to epoxy so when applied it doesn't dry, it actually cures. The Line-X shops have special two nozzle sprayers that mix the two parts as it's applied.

Back on the issue of belly pans: On the K75S I've been playing with lately I discovered that it's much easier to get the K75 BP properly mounted if the fairing radiator panel is removed so it doesn't get in the way of the top front of the belly pan. It seems like extra work to remove and then have to reinstall the radiator panel but IMO it's worth it because it makes getting the BP on properly fitted so much easier.
