They are 2 different types of suspension, the CR has leading link forks and the R1 has girder forks, both designs pre date telescopic forks, my 47 CZ came with girder forks
Its only a frame that i'm going to put a yamaha 2 stroke engine into. Will actually build a "leafer" front end (like an old 20's Indian scout, my dream vintage ride)for it as the forks are long gone, going to start on it after i build my 1950 BSA that has a honda engine in it. Here's a mock up of the BSA, got crappy pitty forks, xl100 19" front wheel, ct90 17" rear wheel, CT125 engine, got a brass 30's Lucas headlight, will make a seat pan out of aluminium and polish it up and suspend it on brass springs, chop up cruiser bike bars, paint everything that cant be polished black and use brass fasteners wherever possible. Only have about 200 in it at the moment. Would love a proper old english bobber from the 30's or 40's but this is all i can afford.
Heres the CZ125A frame
