Kingpin Bolts

This is a pair of CNC machined steering kingpin bolts for 2 wheel drive Rokon motorcycles. They are made out of pre heat 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.
Later (81 and up) kingpin bikes do not have the kingpin thread drilled all the way thru. These bolts will be too long for these bikes. You will have to drill thru and tap the frame to install these bolts. I am not exactly sure what year Rokon stopped drilling the holes thru, so it is a good idea to check your frame before purchasing these extended bolts.

Bushings sold seperately.
