I agree Phil,they seemed to left the factory with what ever bits were around! The Racing Brochure for '93 models show three spokes and a tank with a breather hump.
That's just fcuking sublime. The milled out clutch casing, those pipes, the dinky rear disk, the not-off-the-shelf ohlins, the matt black marchis....... hmmmmmmmm...........
Very nice indeed. I'd be scared to take that on a trackday. most of the bits that are likely to brake will be irreplaceable. you might want to think about getting a standard set of rear sets, just in case.
As for non-original bits, Brembo narrow track discs and calipers were not invented yet in 1993.
