TWM CNC Aluminum Chain Adjusters
First-class Italian engineering and machining from TWM Special Components, part of the Marchesini family. Designed for select BMW motorcycles, these chain adjusters help set chain tension and align the rear axle with precision while adding a premium machined detail to the swingarm area.
CNC-machined from billet aluminum and finished with durable, high-quality anodizing, TWM chain adjusters are built for riders who want accurate adjustment, reliable function, and a clean race-inspired appearance.
Also known as WSBK-style chain adjusters, they are designed to make rear wheel removal and tire changes easier on applicable motorcycles without disturbing the chain tension setting.
TWM chain adjusters combine functional precision with the kind of detail and finish that can transform the rear axle area of the motorcycle.
