Description

This is a pair of CNC machined steering kingpin bolts for 2 wheel drive Rokon motorcycles. They are made out of preheat treated SAE 4140 steel to a hardness of Rc 35. They have grease fittings installed. They are long enough to use all of the thread in the mounting holes. It is a good idea to chase the threads in the mounting holes before installing these bolts. They are supplied with 2 radial needle bearings and one needle thrust bearing. No modifications are required to install these kingpins and bearings for bikes made before 1981.
Later (1976 and up) kingpin bikes do not have the kingpin thread drilled all the way through. These bolts will be too long for these bikes. You will have to drill through and tap the frame to install these bolts. I am not exactly sure what year Rokon stopped drilling the holes through, so it is a good idea to check your frame before purchasing these extended bolts.
