standard and 's' exhausts are the same. rear link pipe is 45mm outside diameter. smallest termignoni starts at 50mm
Going off topic....but pretty sure my Termi's are 45mm as I was measuring the link pipes this week. They were purchased separately so maybe that is the reason why. Will measure them.
The 2005 onwards 999S also had ti rods from what I read and a few other bits, more or less the early 999R engine.
very wrong indeed. different bore different stroke. different cases early 999s had Ti rods any 999s engine is not any version of the R
as I understand it, ive read it somewhere but cant find it right now. they all have ti rods it made reference latter to the latter S having heavier internals but the same Hp. it was deffo a cost cutting change to save production costs
they werent im afraid they had a few very minor detail changes more or less to cut costs. a few oil lines were different. I will find what I read and post back of course if someone has a parts list you can cross reference the rods crank valves and piston part numbers
Sorry to hear about one more 999 with bearing failures - I trashed my 999S main bearings + cracked the casing on the track end of July and we are now rebuilding the engine with a pair of used casings. The parts are insanely expensive and I'm not convinced that this will not happen again which is why I bought a Suzuki GSXR750 K7 trackbike as 'spare'. I have the same frustrations that you do as I had just learned to ride the 999 and got it properly setup etc. etc. and then the thing exploded in my face! I have now used the Suzi for a couple of months and I am reluctant to switch back again as it takes some time to get used to a new bike and get the lap times down. good luck with it Jim
Hi Jim, so you are in a same situation like me thats a shit , i just hope that the bearings are not specified and i can use there other bearings fro example KOYO or some kind of german bearing because as you sad god knows how long it will runs whitout any problem. Thats funny that after 12000km can happen this kind of problem , some people doing at one season more than 15000km and with this bike after every season i should split the fuckin whole engine for a rebuild? You changing also the other bearings or just the main?
To put things slightly into perspective I know someone who purchased a brand new 1098, at the time, and did 40 trackdays with it many of which were open pit lane or abroad and had no problems at all. The key is to try and produce a decent well built and possibly blueprinted engine and then things should be much better. Ducati's are definitely more fragile than a lot of Ja bikes and I think that has to be expected if you are going to use one for a lot of trackdays. As a final point I have two Suzuki RGV250 track bikes and between them they have broken three gearboxes and totally destroyed a crank and a barrel. There are bikes about that are just as fragile when pushed hard.
ahhh man RGV... I just loved those bikes so much. never ridden one but always wanted one back in the day...
We have tried to find replacement bearings and it is possible for the gearbox bearings but we could not find a cheaper replacements for the stupidly expensive main bearings. You even have to buy the bearing sleeves too as the main bearings are housed in sleeves inside the casings. In my (hopeless) case, bearings AND sleeves AND casings were toast!

Jim , thanks for the nice pohotos i will do the same like you did i will make a pictures of each steps and i will upload as well. So you say that the bearing which near the front sprocket i can buy from other manufacturer. What do you think if the engine will be splitted then should i change the main bearings as well?
