SITTA Racing aluminum sprockets – Made in Italy
The quality of SITTA sprockets speaks for itself – they are used in Moto 2, Moto 3, Superbike, Superstock, Supersport, CIV (Italy) and CEV (Spain) Racing.
Milled from 7075-T6 aluminum
Sitta was founded in 1993 and certified its sprockets according to UNI EN ISO 9000/2000, in order to maintain exceptional quality. Sitta sprockets are distinctive and each unique design is manufactured from 7075-T6 Duraluminum, which is normally used in aviation.
The tensile strength is about 11 times that of pure aluminum
All sprockets are anodized to prevent oxidation and to minimize wear.
Each sprocket is fully machined from an aluminum block with extreme accuracy.
All sharp edges are removed in order to achieve optimum stability.
Only available in 520 pitch the HR20GP (previously called the LR18GP) is a sprocket aimed at any rider who requires the absolute best sprocket available for racing or trackdays.
As the sprocket has been specifically developed for a race environment, it is limited to only 3 SITTA product codes and only in 520 pitch:
201H (Marchesini, Rotobox, OZ, BST)
204Y (BMW HP4)
The HHS finish in black only is also only available for the HR20GOP (previously LR18GP) sprocket. We cannot supply any of our standard SITTA Pro sprockets in these specific finishes. The HHS finish will outlast our hard oxidise finished sprockets.
