Front Sprocket Change
1 - 20 of 21 Posts
Have you
already jumped up a couple/few in the rear? The front sprocket is more of a dramatic difference and you may want to work with the rear first. (makes the bike more jerky) I just went up one (back to stock 15) in the front because I had both sprockets done and it was way too much...it's just right now.

My bike
Stock = 15/36
Delivered = 14/42 (practically stunt-bike gearing...I would have been down on my track day in the rain if I still had this aggressiveness/stupidity)
Now = 15/41 (very nice gearing...still aggressive but not too much and so much smoother, better bike overall)
Remember I'm a new guy...not only was my gearing much more aggressive than racers I know, it was not easy to ride. The thing wanted to redline leaving a stoplight in 1st! Every shift was jerky unless I was full throttle to redline...couldn't tell if I sucked as a new guy or if it was the bike...thankfully it was just about all the bike.
And I recommend changing all three (sprockets and chain) if you have a reasonable to significant amount of mileage already on current gearing. IMO they should ideally be all-new and run-in together.

A couple of sources
DP makes F/R aluminum ones right off the Ducati site...or your dealer might stock them. They're a darker gray almost like my swingarm if you've ever seen it, nice look. Then they have some other "special" ones which I don't know much about... http://www.ducati.com/shop/category.jsp?catid=cat1040140
Driven also makes nice F/R black (and other colors) aluminum ones: http://www.drivenracing.com/ The site might look cheesy/run of the mill but they have been condoned by my tech who builds and races.
FYI DP also makes a red chain if you're interested. Any gold chain looks great with the DP sprockets - what I have now - and just about anything else you pair a gold chain with. But I think the red chain will look kickass with the black sprockets, that's just more winter-time stuff that I have planned.

If I changes one - Id change all 3 - my 749s was ridiculously tall and I went down 1 in the fron up to in the rear - much nicer. Personally, I also like the 520 conversions when I do sprocket changes - so I go all new anyway.
How come yours came 14/42 instead of 15/36?

No problem
If these guys are racing the 1098s there has GOT TO be a larger sprocket for the bike...contact Driven directly because maybe the site is not updated or another sprocket will fit. You can also try AFAM and Sprocket Specialists...good luck!

Front Sprocket
My bike was delivered 14T front/36T rear and I want to change the front back to a 15T and then as was suggested, play with the rear sprocket to get the 'best' final drive ratio.
The gearing is way too low (all to obvious even though I am still running it in) and I would imagine the fuel economy would improve a bit with higher gearing, too.
I am assuming there's a big jump to a 15T over the 14T but I don't really need to be pulling wheelies as I take off from traffic lights!
Cheers,
J

I was wrong!

Doh! I was wrong! My bike was unchanged from standard, received it as factory with a 15T front sprocket. Makes me wonder what a 14T would be like! OMGThe Evil Dr J said:

I went to a 14T front, and just changed it back to the stock 15T.The Evil Dr J said:
I wanted first gear back! With the 14T it was too easy to pick up the front end, and I would short shift to 2nd before hammering the throttle. Also found with the 14T that I was getting a fair amount of wheel hop on 2-to-1 downshifts.
Of course, in a couple weeks, I'll probably decide to go back.
Hey yossarian, how was 2nd 3rd and 4th with the 14 front. example--- coming out of a tight corner in 2nd and rolling on the throttle to 3rd, etc. Also downshifting from 4th to 3rd and 2nd when going into a tight corner? thanks in advance.
Don't forget...
your rear also comes into play. I can tell you that my setup was violent...without a slipper I would have locked up my wheel a lot especially at the track. On a rainy (first) track day that would have meant an asphalt sandwich.
It's nasty when you can hammer it in 6th and smoke anyone without downshifting...but there is a happy medium between stock and what I have and I think I found it. My bike is still quick as hell but a lot smoother.
That said, front sprockets are cheap so try it...worst case you hate it and you can swap it back. Sell the other sprocket or keep it for if/when you want the more aggressive gearing.

Any gear above 1st was fine, no problems. It just seemed like the only time 1st was useful was taking off from a start; I'd upshift and never see it again until I had to stop.azduster said:
Like another poster said, front sprockets are cheap, and (relatively) easy to swap. If you hate the change, you're out $30.

chain wheel ratios
Guys,
Here's a great link that tells you the top speed in each gear, using standard chain wheels, (15/38 on the 1098), and then shows you increase/decrease in speed and rpm for each gear when you change either/both front and/or rear chain wheel(s).
