Corona Vampire Special 219

High quality 219 rear sprocket made in italy, patented.

Its exclusive design reduces the frictions and it guarantee a great flow which enhances the engine power. Supplied with a

surface treatement that harden its consistence for a long last. During the ''release'' the chain roll doesn't face any

resistence which it can be found on the common rear sprockets, due to the tooth profile and the next tooth lowering.

Crafted by ERGAL 7075 for the best lightness and the best quality. The OX-W ISO I0074, MIL-A 8625 Type III hard

anodization process containing titanium oxide, allows to lower the roughness for minimum friction and anti-seize

properties.
