Ducati 848 Evo, Sprocket Size?

I suggest you invest in a Rental QD sprocket hub - although it makes first time change more expensive, any subsequent sprocket changes will be easier and cheaper.
Not sure what size you need - do you know the standard front and rear gearing?

 

The long held advice for gearing on track is to drop one tooth off the front and go two up on the back. For road use I would go two or three up on the rear and leave the front standard.

Benefits of 520 is less rotational mass. But it wears out quicker. If track use is go 520. Road I’d chose appropriate to the mileage I do. Interestingly the Panigale v2 has a 520 chain as standard.

 

I have run 520 on a number of bikes (748, 916SPS, 749R and M1100S) - never had any problems. As I don't do big miles longevity is not an issue.

 

I would go to either a 15/41 (or 42) rear, or I would drop to 14/39.

the Renthal hub is a good shout, if you can get one, they seem to be permanently on backorder.

if you want to go to non standard sprocket sizes, 520 will be your best bet, as that will give you the most range of sizes. 525 will likely only give you stock sizes or thereabouts.

the reason I’ve suggested going 15/42 is because the smaller the front sprocket the higher the chain where, so this would give you better longevity, however just check how bigger sprocket you can fit on the rear without swingarm clearance issues, you may end up having to go 14/40-41 if you want shorter gearing.

I have to say the 848 benefits hugely from shorter gearing, it’s so over-geared it chugs in 6th at anything less than 100mph. I had 14/39 with OEM sprockets but wish it was shorter again as it helps you stay off the clutch in low speed stuff for sure
