Bought for project and now have change of plans. EVR Slipper clutch to suit Panigale 899. All parts present and correct,including instruction sheet. The large washer was missing when I took receipt of it (typical). I've sourced the replacement from EVR Italy. You use the oem clutch plate springs and clutch plates. The seller informed me it had only been used on a handful of track days, which stacks up looking at the complete lack of wear on it, including the main hub. £450 delivered. Or collect Swindon.
