Hey guys, wondering if anyone can help me find a sprocket to fit! I purchased wrong size based on a chart a website gave me, and looking deeper into it, can't seem to find what I need?

I am looking for a 15t front 47t rear (steel) for a 525 chain.

Thanks for any help!?!

Seriously, 47-tooth?

The 900ss comes stock with 15/37 and a lot of owners recommend 15/41 for street and track.

I've never seen a 47-tooth rear for a Ducati.

Just do 14/40 — it's exactly the same gear ratio as 15/43. You can use the same chain and the 14-tooth front is inexpensive.

My 620 Multi came with a 15/50 setup.

I changed it to 15/45 when I put the 800 engine in it.

You want the 50?

On my 2002 900SSie I went from the standard 40T rear sprocket to a 43T, as many others. I wanted to keep the 15T instead of going to a 14T.

Going 47T rear seems not logical.

If your chain breaks the chances of it wadding up and breaking the case are higher if there is more room for it to come off the sprocket. This is half the reason case savers work, no room for the chain to come off the sprocket. Also with the 14t your chain can rub the swing arm. As long as you’re buying it all, go 15t on the front.
