Replacement Motor Sprocket For Late Harley-Davidson Big Twins

New to the Evolution Industries line up of driveline parts is the 34 Tooth Motor Sprocket for 2006 & later Dyna and 2007 and later Big Twins models. It eliminates the compensator and runs solid in your primary, preventing slippage on your hot motor set up. It also eliminates the issues of disintegrating stock or Screaming Eagle  compensating sprockets while lowering driveline noise level. At 4.770 lbs, this sprocket is over half the weight of the stock pne, reducing the rotating mass. Works with any oils designed to go into the primary , whether factory or after market oil. Evolution Industries. Made out of high strength 4140 tool steel. heat treated then black oxide coated. Evolution Industries. 909-594-7959

    just like an unsprung clutch in a car this would add harshe-ness to the on-off throttle response right? not that bothers me yet, but for those who mind a little “jerkiness” probably ain’t the product for you.

    How will the crank bearings handle this?

    Agreed. The compensator absorbs a lot of shock in the drive line. A belt drive at least has a little stretch in it, but those chains could be harsh. Probably not for the typical weekend cruiser.

    Isn’t this meant strictly for racing bikes? Why would anyone want to eliminate the compensating sprocket on a road bike?

    You could shear you crank !

    Racing only.
