Twin Shock Posted January 23, 2009 Share Posted January 23, 2009 Hi, Open to suggestions on what combination of sproket sizes would be best for a 1969 yamaha dt1-b 250 which will be used on the road only, Thanks for any info. shared. Yamaha offered many different final drive ratio's. Counter shaft sprocket's from 13t-16t, and the rear from 40t-51tT. The higher number of teeth on the rear sprocket will raise the ratio # The bigger the rear sprocket you lose top end speed but gain torque. It is the opposite on the countershft sprocket. Alot cheaper to work with the little sprocket. Link to comment Share on other sites More sharing options...
