This chain kit is designed for street and racing motorcycles over 1000 cc with high torque and power, or where maximum strength and chain lifespan are required. The kit consists of carefully matched components from leading global manufacturers.

Chain EK Z/3D

EK Chain set out to produce a premium chain that was as beautiful as it is strong. An impressive outer plate shape that offers a curved form to reduce weight and increase appeal is connected together with inner plates and pins that feature lightening holes to further reduce mass.

• 200 g lighter than most any other current high performance chain


• 520 chain has 9,400 lb tensile strength


• The exclusive SX2 Ring leads to 30% reduction of friction (compared with our exsisting products).


• Chromium Carbide pin surface coating increases hardness and reduces chain wear.


• Our ThreeD parts are precisely manufactured, leading to a great improvement of transmission efficiency.

Supersprox Front Sprocket

Supersprox countershaft sprockets are factory-team spec parts (used in WSBK, MXGP, and Rally) made from ultra-durable, carbon-impregnated SCM-435 (18HGT) steel for maximum strength. They feature a lightened design with radial holes or slots, an ultra-hard surface layer to reduce chain friction, a black oxide coating to prevent corrosion, and self-cleaning grooved teeth on off-road models to extend chain and sprocket life.

Supersprox Aluminium rear sprocket

Used in racing since 1959, Supersprox Aluminum Rear Sprockets are the ultimate choice for maximum weight savings. Precision CNC-machined from world-class 7076-T651 aluminum, they feature a special tooth design and mud-clearing grooves to extend chain and sprocket life, finished with high-quality durable anodizing in various colors.
