Bought a Carbon Belly pan ages ago, and I can't be bothered to try and make it fit the S4R. I think it's for a M900 type engine. Now the bad point the front has been cut down to match the original cut out for the exhaust. I didn't mind as I'd have to mod it a little further for the S4R, you could easily make some mesh to sort this out and improve air flow if you liked. Anyway, these are just over £200.00 from the chaps in Germany, so I'd take £100 ono for it. I'll have a S4R carbon hugger for sale in the near future, be looking for about £100 for this. Or if you have a carbon sugar scoop and duck bill for a S4R, perhaps we could come to an "arrangement". I'll post photo's if anyone is interested...
