13 tooth CBR600 F4i sprockets

[Daves]

AFAM sells 13T steel front sprockets in 520 and 525 chain sizes for $28.95 each. This may be easier than ordering 12T sprockets from Sprocket Specialists in bulk.

Any teams that used 428 chains (Milwaukee maybe?), please let me know if you used a steel or aluminum rear sprocket. Were there strength issues with an aluminum sprocket?

If you are looking for manufactures of 11-13 tooth sprockets check Micro-Sprint car chassis builder/parts websites. they generally run 11-12 tooth at the countershaft
