Lex, the 750/1000 formula died with a little gem from Honda called the CBR900RR - WSBK is dictated by the market - you of all people must respect that!
The CBR900RR b/c riders couldn't get their hands on RC30s and RC45s due to high prices and low production quantities. The original CBR900RR was about 125hp, which is reasonable for expert riders who want power on the street or at a track day. The latest 1000cc SBK engines produce nearly 200hp, an increase of at least 50% over the old 750s (depending on the bike in question). No public roadway (spare the Autobahn) or production tire can handle that kind of power, and most tracks are not equipped to handle bikes with that much power.
I do not wish to stop the production of 200hp SBKs, but I think the Japanese would do well to use SBK to promote a different kind of product--something similar to the bikes that built the SBK industry.
