Might have been, but i have 04 Bullit and the top tube is different ( just Google 2004 bullit) then they stopped manufacturing them around 07 and after a short brake re-relased it with the newer frame design
The top tube is different because this is a small. The only Bullit with a straight tube. Mediums and bigger have a kinked top tube to keep stand over low.
Also they stopped making them in 05. Google if you want to I guess......
you are right, everything looks the same except for the top tube
the new ones ( 2009+), after the redesign are pretty much the same thing anyway
