chain
 

just ordered a D.I.D chain, 525, 94 links. looking at other chains on the web i notice most are 525, 120. is the one i have ordered ok? It is listed as the right chain for the 996,996R,998R. Is it better to have more or less links?

Hey adam

I just got a DID525ZVM 94ZB, the bloke I ordered it through said that was the correct chain.

Does that help. :cool:

Depends on the size of your sprockets, but I would guess you would have problems tensioning a 120 link chain on a 9*6;). 96 link on mine with larger rear sprocket.

can you believe it, I go to this bike shop all the time, know everyone there. they quoted me £100 for the D.I.D 525vmx 94 chain, saying he was knocking off a tenner, just looked at M&P, same chain £74.99:o the shop have ordered it now although I havent paid yet. Is that a p**s take?

I am going for the standard front and back.

If it's too long take a few links out :bouncy:


If it's too Short OH S*** :roll::roll::roll:

i think with standard sprockets on they are about 96 links so should be long enough

You've got a 16th front sprocket on there Adam.

did you put that on Tim or already on? is the standard 15th

I did put it on, the standard is 17t.

She just pulled a lot better with one tooth less on the front. This also increased the wheelbase and gave me an even better excuse not to be able to pull wheelies!!!! ;)

Tim:ninja:

May be this will help

Imagine a 996 with 14/48 gearing!

I'm just about to change to 14/39 ...

Actually saw a bloke running 15 48 or 14 48.

Lasted half a track day before wrecking himself and the bike.

14/48

I think you would really struggle to keep the front wheel on the deck!

My 748s has standard sprockets. Under some serious throttle in 3rd it doesnt even raise an eye brow.

Me mates 995i Triumph has a reduced front sprocket and lifts up like a C90 with nitrous.

Does anyone recomend changing the front sprocket on me Duke ?

Common consensus is that as the 748 comes standard with a 14th front that if you want to lower the gearing you should go up on the rear.

Is it common consensus that the rear mod is the way to go ?

Or should I just leave it standard ?

Delooney

It's up to you really. If you're happy to sacrifice a little top end for more acceleration then go for it. For a 748 I would add teeth to the rear sprocket, go up 2 or 3 and you'll notice the difference I think. If you want a big difference add more but there are implications on your ride height so if you do it yourself make sure you measure your ride height before you start goofing around and set it back to that when you're done.

My 996 standard is 15/36 - I went to 14/36 and now I'm going to 14/39 :devil:

I don't use the top end anywhere so I'd rather have the seat of the pants acceleration.

Rattler how did a 16 tooth front lengthen the wheelbase?? To me thats a larger than std sprocket which would shorten the length of the chain ....unless you fitted a longer chain!!?

I think 15/38 is a nice compromise on the 99*s

Sorry, my fault - too much sauce!!! I went one down on the front!! a 14t I think!!!
Tim

Yes you did Tim;) I did the same.

I agree that 15/38 is a good choice for 998's and 999's, but not for 996's. Unlike the other two that have the close-ratio, the 996 has a standard-ratio gearbox that has taller 3rd-6th gears.

A better choice for a 996 is 15/43 (98-links.)

What are the implications of running 14/39 Shazaam? Or even 14/43 ?

Blimey, a 43 on the rear, does that come with sand bags to put over the front wheel? also are we talking large rear sprockets for the track, road or both. Dont know why you need to go that large for the road.

Adam your 996r is a 998cc.........youll be allright! 15/38 (have i just corrected the great one??):lol:

this could be your lucky day andy, yepI think i will stick with the 15/38. thankyou.

You know you want the 14/43 ;)

:lol: :frog:

16/64...:sing:

:lol:

tp, is that the time of the next train outa town?

andy, is that the time the train comes back into town:lol:

[Edited on 9-2-2005 by adam]

:)

I've been running 14/36 for over a year and I'm happy to sacrifice a little top end for more acceleration by moving to 14/39

Sorry, let me clarify ...

Andyb made a general suggestion that 15/38 was a good choice for 99* bikes. I just wanted to point out that the 996's are an exception because of their much higher gearing.

The 996R's use the close-ratio box like the 998's and 999's.

I wasn't suggesting using 15/43 for a 996R, adam.

phew, thanks Shazaam.

No definitely 14/42 for you Adam!

:lol:

I'll get my coat!

The following engine speeds in 6th gear at 120Kmph will give you an idea of the difference in a 996:

15/36 3,890 rpm 94-links (stock gearing)
14/36 4,168 rpm 94-links
14/39 4,516 rpm 96-links
15/43 4,647 rpm 98-links
14/43 4,979 rpm 98-links

Oh man, Shazaam. I've been trying to follow this, wrote down your advice on a yellow sticky even! Now I'm totally confused. I think I have standard chain and sprockets on my 996. I want to increase the low down torque without affecting the top end enjoyment too noticeably. Is there a solution for that? :puzzled:

Ok, so I'm cool with that. My question is more on what type of chain to run 14/39 or even 14/43, seeing as I'm now thinking of 14/43

The 996 and 996S bikes are the highest-geared Ducati superbikes. Extremely over-geared.

If you replace the stock 15/36 set-up with 15/43, as I suggest, your tach at 70mph will read about 750 rpm higher (4,647 instead of 3,890) but you'll be using all your gears now, instead of just the bottom four or five. It'll be much easier to launch off the line as well.

I get the gist, but this is a bit too technospeak for me. What does this mean

"your tach at 70mph will read about 750 rpm higher (4,647 instead of 3,890)"

:puzzled:

So a 'tach' is the thing that shows the revs, right?

Hats off to ya. That you can quote figures as accurate as 4,647 and 3,890 on chain and sprocket change.


Whatever the outcome of the know all quiz, I'm sending you a prize :D:D
