"
11T tooth steel gear, 5/8" bore, 410 BMX bike chain width.To be used with a 5/8" keyed shaft. Two set screws.
NOTICE: These gears are not designed nor will they fit the output shaft of engines of any type unless the output shaft is 5/8". None of the 2 stroke bike engines have 5/8" shafts.
Please Also Note: This gear will accept a 415 chain. A 415 chain is wider than 410, but all other aspects of a 415 chain are the same as a 410 chain. The gear/sprocket will be quite thin for a 415 chain, and will work in some designs."
