Hi MTC Engineering, These are the requiered cores for a 2008-2011 ZX-14 Gen 2 clutch kit (GMS-ZX14-500). I placed initial order via phone through Eric. CC info has already provided. Included: 2012+ zx-14 clutch basket. this has same ring gear as the 2008-11 2006+ zx-14 OEM inner hub. Also, in box is a pressure plate from a 2012+ Gen 2 (GMS-ZX14-2-500) I run in another bike. Please replace the buttons and ship it back with the above mentioned 2008 Gen 2 (GMS-ZX14-500) order. call with any questions. Thanks,
