Visit their web site at: OLD S'CooL MX Restorations Eric shared the following story about this bike and it's construction.
"I was approached by a gentleman who originally wanted a run of the mill, standard and typical CZ race bike. We talked of the initial details of the build until I realized, I would just be building another standard CZ. It was then I realized I didn't want to do a stock type bike and had the thought of building him a special OLD S'CooL type bike with some unique and rare features. I wanted the bike to look and be set up differently than any other CZ out there. Brainstorm...How about a Centerport Falta replica? I was already doing one of these unique CZ's for my personal collection which at this point was only 50% completed.
Customer thought it was a great idea to have a special bike as a racer and a collectible piece down the road. So, here it is after 7 months of planning and building. The bike is basically a 250cc reed motor with a handmade center exhaust port exiting the cylinder like the works bikes. The frame is a NOS 513/514 series frame with a 1975 era rear sub frame assembly. It has 8" of travel up front, 5" in back with a whole lot of neat parts in between. Billet triple clamps are Czech made in the motherland as well as the 8 oz all aluminum rear brake plate. Reed valve is an old tried and true DH 4-pedal reed unit coupled with a 34mm Mikuni. Electronic flywheel ignition by B.U.S. fires the plug magnificently. Engine starts on first kick every time! Excel rims, Buc's spokes, Pro-Form Racing pipe and a premium CZ chain. Nice slim alloy fuel tank and a new Bertus period correct seat assembly to top off the old school look of the bike.
Everything is brand new except the fork sliders, hubs and engine cases. The bike runs better than stock but not as quick as a maximum ported race machine. Five speed transmission is a Falta 250 gear ratio'd unit that shifts like butter with a dry clutch. All in all a great little CZ in which i thoroughly enjoyed taking on. You don't see very many of these around"
