Yamaha YZF-R1/R1M 2015> AFAM Front Sprockets
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. 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!
