My swingarm drive for the Qulbix 76R and 140R is now available. It's designed to fit the 165mm dropout width Qulbix swingarm on both models.
This drive requires a left side drive #219 kart sprocket. I'm also producing billet aluminum hubs that allow fitment of the sprocket plus disc brake rotor. The hubs have sealed bearings and a solid 12mm 4140 axle. Thick 36 hole spoke flanges. The current design has the left side threaded for a 1.375" x 24 tpi freewheel. The standard left side sprocket is a 96 tooth. Combined with a 12t motor sprocket this creates an 8:1 reduction to the rear wheel.
The last part required for the drive system is an offset brake caliper mount. It replaces the standard Qulbix mount that attaches inside of the swingarm. Milled from aluminum billet.

The Big Block will run all day at 3000 watts. Blasts of 6000-7000 watts provide light motorcycle performance. Weight of the complete drive is approximately 12 lbs.
