i went from a 44 to 40 tooth sprocket. the diference is night and day. i like to cruise around 27 to 30 mph and with the 44t it really vibrated and engine was reved up alot. the 40 it just cruising at the same speed but without winding out the engine. lost little or nothing on low end but top end gained around 5mph. as to date the best upgrade i have found
