Hi Guys,
I have a brand new 520 conversion kit that I got with my R1 when I bought it. I never installed it and I sold that bike. It is all brand new in the packages.

The front sprocket is a 16tooth vortex PN 3271-16
The rear sprocket is a 47tooth vortex PN 435K-47
The chain is a DID520ZVM2 x2ring that is gold and black. Part number 130ZBL which I am assuming is 130 link.

These probably fit some other bikes. Check vortex website to see if the part numbers fit your bike.

$160 for all of it.

Thanks,
Nathan
