To solve the issue of fluid seeping from the 1st generation Diavel clutch and front brake reservoir lids, Ducati made available a reservoir update kit. The kit comprises, a new clutch reservoir and new bladders, plastic spacers (the update) and lids for both clutch and front brake reservoirs. I have no idea why Ducati didn't include a new front brake reservoir as well but they didn't. £100 posted to a UK mainland post code. Andy
