{"product_id":"ducati-rear-sprocket-spacer-71311861a","title":"Ducati Rear Sprocket Spacer 71311861A","description":"\u003cp\u003eDesigned for drive chain alignment, rear wheel hub spacing, and drivetrain stability, the official Ducati Rear Sprocket Spacer (Part Number: 71311861A) maintains the exact lateral offset between your rear sprocket carrier, wheel hub, and swingarm assembly. Operating with a worn, scored, deformed, or missing sprocket spacer throws off chain alignment, accelerates sprocket tooth and chain wear, and places dangerous lateral stress on rear wheel bearings. At On Yer Bike, located just outside Aylesbury, we supply genuine OEM Ducati drivetrain hardware, rear hub spacers, and chassis components to keep your motorcycle running smoothly and safely to factory tolerances.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eManufactured to Ducati’s strict original equipment engineering standards, this genuine rear sprocket spacer is precision-machined from high-strength, wear-resistant metal to exact inner diameter, outer diameter, and width specifications. Its hardened bearing contact faces ensure true axial clamping preload when the rear axle nut is torqued, preventing hub binding and protecting oil seals from premature wear. Installing an authentic OEM replacement guarantees accurate chain line geometry, smooth rear wheel rotation, and trouble-free installation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eNotice: This item is sold individually as a single rear sprocket spacer; rear sprockets, cush drive rubbers, wheel bearings, axle nuts, and oil seals are sold separately unless specified in the schematic.
