    Been lurking since I bought a used 990R last week. The bike came with the KTM branded H & B panniers and I'm trying to figure out the best way to mount a couple Rotopax gallon tanks to the bike when I have the panniers attached. After a 325 mile ride yesterday, I learned that bike sucks alot more gas than my XT225.
    I searched the forums, but couldn't find any good ideas except on the upper seat plate - and I want to tie a bag on there.
    Thanks in advance - I think I'm catching the KTM fever.

    I'd post a pic - but can't figure out how.

    I mounted the Rotopax to my rear top rack. It's an aluminum plate similar to the one the Black Dog sells. Rode 3K miles this summer with it and it worked great. Jessie panniers on the sides.

    Keep an eye on your sub-frame guys. I, and several others, have broken the subframe by carrying one 1.25 gallon Kolpin tank on the rear toprack.

    Seen several comments on this happening but curious why it's only been mentioned with the 1-2 gal roto or similar? Surely the luggage some load onto the rear in the same place is heavier but haven't read of any problems with that...


    And so I don't derail the thread...google images of numerous roto mounted to the 990

    Maybe these people installed the rear rack and loaded it down with fuel without the Pannier racks which beef up the rear of the bike. The 1 Gallon Rotopax weighs in at 5 LBS empty or 11 LBS when filled.

    I seem to remember someone mounting rotopaks on the tank protectors. Maybe that's an option?

    The issue with the tanks is their rigid mount. The plastic retainer that the tank sits on is bolted tightly to the tail rack, which is bolted tightly to the subframe. As a result, every bump in the road transfers that 11 + pounds into the subframe- more specifically to a specific weak point on the subframe. The subframe will crack where the plastic attaches to it by a screw, from the underside. Luggage racks make no difference on this. The end of the subframe- about 3" in length, is the part that breaks off.

    I suspect that if you were to ride street only, the tank and subframe combo would work out just fine. As soon as you take if off road, the risk of breakage is pretty high.

    I broke my SE subframe within about 2 months of buying it. I cracked my crank case on the first ride.:bluduh That was before anyone made an aftermarket skid plate or side stand relocator.

    What about these guys with the GIANT tailboxes? Are they breaking subframes?

    Seems like a LOT more strain than a flat 11 lbs of Rotopax.

    Thanks for the feedback. Looks like there's no easy answer if you're riding offroad. Those Rotopax seem pretty slick, just wish that back plate was more solid.
    I just found out I live right down the road from Black Dog CW. I think I'll pick his brain.

    Broke the tip off my subframe recently (2012 Adventure R) running a Trax top box with very little load (10-12 lbs max including box). I've been running it that way for some time, broke around 15,000km.
