Had the 999s mono since June and the Termi box with tail light assembly underneath is falling down / loose below the rear frame, and pivoting on the forward bolts holding it on. I was told by another 999 rider who actually noticed it that this is a common problem but I've not yet found another resource or photos / diagrams so I can work out how to fix. Grateful for any assistance. Thanks
On my 999 the exhaust bracket at the end of the subframe had detached from the two welds. Worst case the subframe could have snapped. The attached image shows a broken subframe, the bracket that went on mine is the last one on the right.
Ah yes, that is exactly it. The bracket with the two welds on the far right is completely missing on mine. Presumably this is stainless and can be welded / fabricate a new one? How did you resolve? Any idea on material? 316? Many thanks.
If yours is a factory 999 mono it will have and aluminium subframe. My local Ducati dealership gave me the name of a chap who does all their aluminium repairs, cost me about £30 to have the bracket welded back in place. A new subframe will cost you about £750!
it is aluminium, which grade i do not know. easy repair for the right welder but for it to be straight it needs to be jigged up to prevent warpage under the heat of welding . By the time you add in fuel, stress and paintl/ powdercoat you should be something close to 100 quid for the repair by my experiences. used ones go for all sorts of money and there are bargains to be had if you keep a watch out. there are three generations of subframe and the latest can be found new on ebay from usa sellers for 260 ish quid the last time i looked. look for the extra bracing to the later gen ones.
cbreeze This is a know issue on the subframes, happened to mine too. Worthwhile contacting your friendly dealer and requesting a new one from Ducati. I had a new black stronger subframe fitted foc!
Thanks all. Have been recommended a good frame welding shop by my mechanic who had a whole race frame built.
Well known failure on early monos. If you contact your local dealer and ask them to speak to Ducati, you may be lucky and get a replacement at cost. I did, and even after 9 years Ducati looked after me and only charged £160 for a brand new clear anodised replacement.
The repair manual on a 2005 999S says the subframe is "ALS 7003 steel tube trellis frame"? Isn't 7003 an aluminium alloy spec?
Better tell the guy with this 999S then Broken rear exhaust mount. - ducati.org forum | the home for ducati owners and enthusiasts
Mine snapped recently, welded and powder coated for 50 quid. Jobs a good un! Not sure where you are based but drop me a PM and I'll pass on a number for the welder. Midlands based. Scrawn #17 - So my pointless piece of carbon fibre bling turns...
If you compare the 2003 and the updated frames, there are significantly more gussets and bracing. Especially around the "ears" where the seat mounts. Here is a nice aftermarket one and not too salty on price: XTEL749M: Lightweight Aluminium Mono Rear Subframe, 749-999-749R-999R
