One kit uses a
genuine 14mm pitch Gates Poly Chain Carbon GT belt with high tensile carbon fiber cords, and the latest Gen 4 curvilinear tooth profile - this is rather important.
The lightened front pulley, is machined in one piece from a billet of high tensile steel, induction hardened for wear at both the splines and teeth, and finally black zinc plated for corrosion protection. The rear pulley is not only a design exercise, but is engineered for optimum strength at minimal weight, fully machined from a solid billet of aircraft grade (6061-T6) aluminium, then Type 3 Hard anodized for wear. Teeth on both pullies are fully machined using a custom CNC ground cutter to provide the proper tooth shape to mate with the Gates belt teeth.
The other is none of those things.............
Quality matters.
BTW, I am the guy that makes the beautiful, properly engineered ones that you would be proud to run on your bike. We are Engineers, as well as motorcyclists, and recognise that not every rider wants the stock final drive ratio, so there is a choice of ratios - a "38T" rear mod for the Super Meteor / Shotgun, and the "16T" front mod for the Interceptor / Continental at:
