Outstanding! I also want a minimum of 52 teeth on the rear sprocket. Need lower 1st gear not 135 mph.OK FOLKS! I have made a drawing of my rear 48 tooth and all the dimensions have been digitized and sent to Sprocket Specialists to be made in several different tooth counts! I have ordered a +6 54 tooth and a -6 42 tooth for the highway.
If you are interested, Lance @ sprocketspecialists . com is his email. Hardened aluminum is what I went with.
