I read the following passage here.

So the saga continues. There was to be an admitedly small number of riders looking to the new CBR600RR, but it was a case of quality not quantity. Then out of the blue we hear a very hush hush horror story about these bikes blowing themselves to bits when put under serious stress on the race circuits by racers. Every team destined to race the CBR600RR pressed the panic button and chased off after any available Yamaha or Suzuki's.

Dosen't look good.
