I bought this one for my 11" Santee Bagger Apes. Works great.

That is exacly the right length! just did my 575's and went with the magnum but in the Chromite..

I picked up a brand new, +6 Diamondback clutch cable off ebay for 29 bucks this winter. I see deals on clutch cables frequently, but you absolutely need to know the length you need, as well as part numbers, and be prepared for the seller to have no idea what application the part is for.

If you look up your bike in the Parts and Accessories catalog, it will let you know what your stock cables are (part number and length), and give cross reference numbers for the upgrade cables.
