it is meant to look that way. they always had a 600 and 900 hornet in the range, then when they updated to the newer models the bigger one had its name changed to cb1000r but they still look the same.
it is actually the exact same bike as the cbr600f. as far as i can see literally the only difference is the removal of the fairing and different bars.
'06 CBR1000RR Fireblade and loads of small 2 strokes!
