I even have the original reflectors. Forks, Seat, Crank, Sprocket, Pedals. The only replacement parts/upgrades are the aluminum handlebars, grips and a 4-bolt handlebar mount gooseneck and pad. These mods were made when the bike was new (for race preparation).The bike originally came with black steel handlebars and clear grips (which were horrible on your hands). About 10 years ago, I regreased and repainted the crank and cleaned and regreased the steering head and wheel bearings. I also replaced the tires and tubes, but they were allowed to sit flat, so the rear tire has some cracking. A very cool original old school BMX bike from when BMX was just getting started.
