I have a Magnesium Forged Marchesini 999RS rear + sprocket carrier for sale - £525 I will include the 'cush' drive rubbers as well but they will need replacing - there are 5 and they are about £4ea from Cresent Suzuki believe it or not. I have just replaced the bearings and used them once at Brands. Few paint chips around the edges as can be seen... (note: rear disc not included)
