The star back Afam Steel-SLK Sprocket 520 the Self-cleaning steel back off-road asterisk of AFAM 520 (SLK+ suffix in catalog number) is executed on the exact equipment with computer management. Teeths are processed according to the last standards for the maximum service life of a chain and more effective transfer of power. The maximum economy of the weight (SL Super Light) thanks to design of T4 of the fourth generation of the black color received by method of an electrophoresis (K Black) and equipment by mud flutes do this asterisk ideal for extreme conditions, from races on sand, the Dakar rally to MX1. Teeth and outer diameter are cut off at the same time. It guarantees that koncentrichna teeths in relation to the center of an asterisk. Technological features: Each asterisk is exposed to heat treatment by means of induction training, and then to a holiday for obtaining precisely necessary hardness for durability and effective transfer of power. To correct any deformation which could arise at these stages asterisks pass via the special machine for editing. The star is made of C45 brand steel (constructional carbonaceous qualitative) with a special corrosion-resistant coating, has the increased durability and durability. Are executed in silvery (galvanized) or black (electrophoresis) color for long protection against corrosion. The normalized steel prevents formation of microcracks in asterisk material. It guarantees quality of a product to offer you safe driving. Surpass standard factory stars in operational and strength characteristics of a star of Afam. Thanks to special manufacturing techniques have the lowest weight among motorcycle stars without decrease in rigidity. Important: It is recommended to change at the same time both stars and a chain. Not the really worn-out star left, apparently, will reduce service life of all set. Installation (use) of stars with other quantity of teeths leads to change of the maximum speed and dynamics of dispersal. * The image of a product has exclusively illustrative character. The actual design of an asterisk can differ a little depending on model of your motorcycle. Characteristics: Internal diameter 125 Intercenter distances 150 Proizvodstvo Japan
