I am looking for a 45T rear sprocket for my Panigale V2. I prefer standard (non-quick change) setup. The only options I have found so far are a OEM sprocket from a SF-V2 or Superlite, which is a QC. Can you point me to a non-QC brand and a retailer for a 45T rear sprocket? Thanks!
What 45t sprocket?
- Thread starter stgatev
- Start date
the non quick change sprockets are a funky design, where the crush drives fit into the sprocket...only OEM are made that way..and ducati does not make a 45T...i think your out of luck, or will have to trust some no name brand on ebay...
honestly 45T is crazy....just drop one in front man...

The V2 comes with 43 rear. +2 on the rear is less of a change than -1 on the front. In speaking with Daniel Deussen, he advised that if I want to change the gearing, I go with +2 on the rear because -1 on the front goes outside the TC calibration range and causes TC issues.
Thanks. I looked up the SF-V2 and it has a 45T stock, but I thought that perhaps there would be some lighter aftermarket options. From what I gather, the Superlite are indeed much lighter, and since I am going with CF wheels, I thought why not look up for a lighter sprocket as well since I will be changing it anyway. The QC looks a bit too busy with all the bolts, and I will never change sprockets in a hurry. But it it is the only option, I might go with it.
With the QC setup, did you also change the cush drive set? I wonder if there is any difference in ride quality.

How did this work out? Did you get the aftermarket 45t rear? I'm asking in part because I'm trying to see if I should preemptively change my gearing before hitting the track on my V2.
But is that true that you can drop a tooth on the front, because it makes the bike fall out of the TC calibration range? I feel like that would be very strange. I couldn't imagine not having a race bike where you couldn't drop a tooth on the front sprocket. Otherwise, you're basically limited to + / - 2 teeth on the rear, unless you want to change chains and try + / - 3 or 4.
Also: the aftermarket sprocket carriers are a bit lighter. Not sure if this matters to you. It does to me, but this is a race bike (to be).

I have not got to it yet. I am also considering the Ducati OEM sprocket from the Streetfighter. Daniel Deussen told me about the -1 on the front causing problems. Perhaps race electronics can give you a wider range of adjustments, but I am not taking that path.

Got ya. I just ordered a -1 front from HSBK, and he didn't say anything about it causing calibration issues.

V4R has no issues with -1 in front. TC calibration is based on tire radiuses that you have to redo anytime you make changes to tires or gearing.
That usually means they are the ones I use. I'd be interested to know if there are reasons for making this statement (and I do generally like the stuff that CNC Racing do).
Just in case anybody is interested - I have a 2022 V2 and I put on a 14t front sprocket (-1) and the gearing was definitely improved. However, I was aware before I did it that the newer bike electronics don't like the smaller sprocket.
I did the tire calibration successfully but it took no more than 5 miles for the dash to start showing errors. Namely the N would start flashing and the gear indicator showed -- rather than a gear.
I put the standard 15t front sprocket back on and bike electronics returned to normal.
So, I went for a 45t (+2) rear sprocket which I have to say proved very difficult to find, as all the suppliers really only want to sell you a standard 43t.
Whilst looking I found that Ducati have an OEM sprocket kit for the V2 Streetfighter - 67621411A which I am reliably informed comes with a 520 chain and 15t front and 45t rear steel sprockets.
But when I compared the price with a Carrier and Ring sprocket set up it makes sense to go aftermarket.
In the end I went for a DID ZVMX 520 108 link (+2) chain which is an upgrade over the original and weighs less.
I kept the standard OEM front sprocket and purchased a JT Aluminium Carrier (JTA770B) and a Renthal Hard Anodised 45t ring sprocket. The JT carrier is very well made and represents much better value for money than the Renthal (D183) carrier and the Renthal sprocket fits both perfectly.
The reduction in weight of the aftermarket sprocket and carrier over the OEM steel sprocket is quick significant and more importantly there were no issues with sprocket misalignment/offset between front and rear.

From what I have read the answer is yes you can drop down both but on the V2 you are going to have the same electronics issue which is also a factor in the QS not working properly.
What's the work around for the computer not liking the gearing changes? Is gearing changes something the can do when, or with tuning?

I think @DeussenEngines (Daniel) had a solution that went with a tune. You'd have to PM him for details or maybe he'll respond here.
