The specs written here for the 1992 model is not necessarily correct because, the CBR1000 model also came in a 135HP model, and that goes for those made before ´93 as well. I believe that the ones with only 100HP is the model made for Schwiss, and the reason for the 100HP instead of 135HP has something to do with the price for insurances in Schwiss for bikes with more than a 100HP.
