This is a build up I am doing for my nephew, I think Kawasaki should update the 65 to look like this.
The bike has custom billet wheels hubs and wheels running 15mm axles and three rear wheel bearings, billet linkage and adjustable pull rods, an aluminum swingarm, and GPX shock with 16 clicks rebound, 12 click and 2 turns of both hi and low speed compression adjustments , adds up to 9.5 inches of rear wheel travel.
the front is 8.3 inches of inverted GPX forks with 16 clicks of compression and rebound adjustments, billet trees .
The front brake is 220mm wave rotor with a dual piston caliper. and 180mm rear wave rotor.
Added the pro taper bars a billet shifter ,custom step seat . And then modified the frame and tank to accept the more modern plastics.
Adding up the weight savings from replacing all the steel, trees, swingarm, linkage, pull rods,rear sprocket, shifter, axle blocks, handle bars, We lost about 8 pounds!!
