High quality 45 Teeth Aluminum Rear Drive Sprocket manufactured by PBI. 

PBI has been manufacturing motorcyle sprockets made to the highest standards for over 40 years here in the USA . 

All PBI rear sprockets are made using 7075 T6-51 aircraft grade aluminum and

are the put thru a proprietory heat treating process.

The end result is an aluminum rear sprocket that is stronger than steel in tensile, yield and sheer strength.

This allows them to outperform even a steel sprocket - - - at less than half of the weight of a steel sprocket !!

 That weight reduction makes for a huge advantage in the whole unsprung weight / rotating mass picture !!
