Like many components there’s more to a sprocket than you might think! AFAM have been making sprockets for more than 25 years and during that time, they have refined their manufacturing techniques to such a level that their standards now exceed those of the OEM’s. Through computer programs, sprocket designs

can be stress tested prior to undergoing tough field tests.

The sprockets are made on precision controlled equipment in a modern 25,000 square foot facility. The teeth are machined to the latest standards, this ensures the maximum chain life and more efficient power transmission. Machining is carried out on a gear hobbing machine. The teeth and the outside diameter are cut at the same time. This makes sure that the teeth are concentric to the sprocket centre. Most OEM’s demand a maximum run-out of 0.5mm, all AFAM sprockets have a maximum run-out of 0.2mm - more than twice as accurate as the industry standard!

Most steel sprockets to be used on motorcycles 500cc or more are heat treated, which changes the hardness of the material. If not done correctly it can produce a brittle part. AFAM use induction hardening to accurately control this process. After hardening, the sprockets are tempered to produce exactly the correct hardness for durability and efficient power delivery. To correct any distortion that may have occurred during these stages, the sprockets are put through a final flattening machine. All aluminium sprockets are made from heat treated 7075-T6 aluminium. After precision machining and flattening they are hard anodised for durability and corrosion resistance.

Steel sprockets are fitted as standard to many Ducati, Aprilia, Voxan and some Yamaha motorcycles. Light weight aluminium rear and lightened steel front race sprockets are used by many of the worlds best riders and race teams including Valentino Rossi, Max Biaggi, Carlo Checa, Troy Bayliss, Carl Fogarty, Michael Doohan, Alex Criville,, Ben Bostrom, Paulo Casoli, Ruben Xaus, Fabien Foret, Jeremy McGrath, Stefan Everts, Stefan Chambon Honda Grand Prix team, Ducati Racing, American Honda, Yoshimura Suzuki, Crescent Suzuki, Yamaha USA and many many more.
