14t gearbox sprockets on SSie bikes
 

I'm a member of www.ducati.ms and the guys on there reckon you can't fit a 14t gearbox sprocket to an 800ss (which is the same as the 750ssie and 900ssie). I say you can - I have one on my 800ss racer - it goes straight on, there's no misalignment and the chain run is straight and free. Yet they still say it can't be done - I've almost been accused of lying via pm!

As a matter of interest, who here is running a 14t gearbox sprocket as well. What are your experiences?

Without being shouted at for not reading the title, I'm running a 14 on my ST and I have no problems.

Me. No reason why it wouldn't fit!

They reckon that all the aftermarket sprockets they can get including Renthal are offset - so much so that the chain won't run on the wear strip or go on the sprocket.

Here's the thread:

Oh my god - that is absolute ignorance of the highest order!

Mine or theirs? :o

Agreed. Tosser!

Theirs!

Jesus, they look at the sprocket and just decide it doesn't fit - in their uneducated opinion. And simply ignore the advice of people who've done it! And Shazaam FFS!

Oh dear ...

Oh, the rub strips are different between ally and steel swingarms too - when we swapped swingarms, the black rub strip off my steel swinger didn't line up properly so we had to use the original white one that came with the ally swingarm.

Also, the swingarm makes no difference in the position of the sprockets (think about it - the sprocket on the engine doesn't move if you have a different swingarm!) which that guy seems to be implying.

Finally, it doesn't matter what the offset looks like on the sprocket, it's how it fits that is important. They all fit onto the shaft and then are aligned with the locking plate which fits into the groove on the shaft - that's how it gets aligned, not shoulder depth!

Yep, no probs here either.

Got them on my 900ssie and 600ss.

Here ya go, ask him to count how many teeth on this...

I'll post a pointer to this thread. Obviously there's something odd going on but, clearly you can fit 14t sprockets to ssie motors.

got a 14T front on my 620Sie motor in my Class A DD bike although I have it fitted with the boss facing outwould so that the sprocket is a bit nearer to the crankcases to suit my chain alignment.
Also had one on the 750SSie when I raced it at Darley the other week, again if fitted without any problems

that will make us popular :D

I'm running a 14t on my 620ie and have been all season. When I put it on I checked both sprockets and boss size / alignment was identical. The chain is in exactly the same place as it was with a 15t.....

Maybe they have weird sprockets....... or weird eyes.... :lol: Just kidding guys, I'm sure it's just a sprocket issue.

I to have run a 14t on my 620ie all year without any problems. :D

I used to run 14t front sprocket on my 1999 750ss ie. I'm currently running a 14t front sprocket on my 2002 900ss ie. I'm also running a 14t front sprocket on my 1995 600ss ie DD bike.

So that's two injected and one carbed Supersport bikes that I've run 14t front sprockets on with no problems.

The pic above is the old carbed bike, but I used the same 14t sprocket on the new 800^H^H 620 engine as well.

hmm
 

Been lurking here for a while but thought I'd jump out on this.

I think we are getting only half the story.

Ok after a lot of reading I find that his problem is NOT that 'A' 14 tooth gear won't fit, it's that it is different and won't fit or suit HIS bike. That other chick was saying she had the same thing. Both these bikes are 06 800 SS bikes in the USA. Anyone know for sure if these are the same or different. I know a 14 tooth fits my bike, 900ssie 2002, I've just gone back to a 15.

I don't really understand why you've brought us into this twpd, I feel no real good will come of it.

All Ducati bikes are built in a shed on the outskirts of a town in Italy. They don't have the ability to tailor bikes to such minute detail as changing the output shaft on bikes for the USA market! The output shaft has been the same since the early nineties, from SS through to Superbike.

Hi Ben,

Check out what Antonye said above about where the sprocket is actually aligned when the locking plate goes onto the gearbox shaft. There's a recess on the splines so there is only one place it can be secured - this means that it's aligned correctly - not the size of the shoulder on the sprocket.

All us guys who race these things run 14t sprockets that are the renthal item from BandC which I daresay has exactly the same part number as the renthal item you guys are getting.

Why don't we check that and clear it up once and for all?

Also...

If you check the Ducati Performance catalogue, they have a 14t front sprocket listed under 44910061A to fit "SS/Sport 600/620/750/800/900"

First of all Ben - it's not a bun fight. I am trying to help and have spent considerable time over on ducati.ms giving various people the info they need to obtain 14t 800ss psorckets - if you've been careful enough to read you will discover that I have three 800's (albeit one in bits) so I do have a very good idea of what I am talking about as well as a wealth of experience with the bike.
People over there are making catagorical statements to the effect that a 14t sprocket is not made or one cannot be fitted - both of which I dispute as I have fitted these sprockets to my bikes. Neither do I appreciate a pm telling me I am plain wrong - how can I be wrong when I've been through this exercise? The parts fit.

These are the same people who also told me that a Power Commander does not exist for the bike - I have two on two bikes using the part numbers recommended by the Power Commander people.

I have presented the facts in a clear manner with all the relevant contact info required to obtain the parts. I cannot be more helpful or precise than that. As they say - you can lead a horse to water but, you can't make it drink.

I brought the matter up here to seek the opinion of people whose knowledge and experience I respect. It is clear to me and others here that you can indeed get a 14t sprocket to fit - there is nothing different or unusual about the 800ss wrt to any other ssie bikes in this regard. How can anything bad come of clarification of this issue?

Over to you.
