Benelli!!!!! Is that the only pic you have???? What a tease!! :rotfl:

With no engine number I would be surprised if it were an "off the floor" model. Seems there's some work that was done to that motor. The US didn't get the actual 92 models, we got early release 93's in the summer of 92. We started here with the RRP, not the RRN. I would assume the pic you have is of an RRN?

Pretty sure the clutch covers ARE interchangeable, here's an AMA Erion Racing 900 of 96-97 vintage. Although I can't prove it, I would guess it's an SC33 engine, but I'm positive it's an SC33 frame.





Most people did the opposite of what you ask because the SC28 covers are lighter.

 

Thanks Ian. The bike(s) in question are these:

The white/red one is the 92 with the interesting engine number. Seems quite original apart from the heel plates and the blue screen.

The black/blue one is a 93' US import with an SC33 clutch cover, but an SC28 engine number and a Two Brothers system. He first bought the US import as it came up cheap and then saw the white one for an equally good price so it would have been rude not to buy that as well Interesting that you guys got silver forks on the early bikes and we got the bronze colored ones.

The black one hasn't run for quite a while and had the usual leaking O rings on the fuel rail and gunked up carbs, but he got it running ok. The white one runs fine, just needs tidying up.

 

Ah yes, now I see where the cover question came from. Yes, subtle differences from what we got on this side. Your 94 model also got compression damping on the forks, which we didn't get until 95 with the RRS. I don't think I ever liked the bronze on the fork tubes. I do like the 2 tone idea thought.

The white one also has too many holes in the rear disk. Someone went to a length to lighten it up, maybe it did have a past as a Guinea Pig racer:idunno:

I'm probably with you though, someone sanded the actual engine number off and thought it would be cute to put HRC on it.
