Jimmy my lad, I wish you well, but you really need to learn your facts better.
The 748R came out at the same time the 748RS came out which was 1999. Why do I know that? Because the 748R was a homologation special, it was a de-tuned version of the 748RS, which started to race in 1999. Ducati didn't start producing motorcycles with shower injectors until late 2000. This is why you see some 748R's with showers and some without. Its safe to say, 2001+ have showers, have the larger CF airbox and most importantly have the ohlins fork/shock.
One thing I was wrong about when I posted was the showa shock on the 1999-2000 models. It wasn't until the late 2000 production (2001 model year) 748R's with the shower injectors, that the Ohlins shock was introduced.
Anyhow, if you want the full history on the 748RS/748R, pick up Ian Falloon's book about the Desmoquattro's. NOBODY has ever posted such accurate information on the internet, not even me. If I had the book in front of me, I'd write it in verbatim for ya.
