Difference with 2002 model ?

[AeroCat4]

I was at the bike shop this morning checking out the difference with the 2001 model compared to the 2002 model. My replacement bike since my crash maybe another red/silver one, but the '02 models looked good - no red though! Didn't get to see the black/blue in flesh but looks awesome on computer!
Anyway, only difference I could see was:
1 - Polished Steel pipes before mufflers;
2 - Radiator painted Silver;
3 - Front wheel axle nut internally recessed.

Any differences with engine or frames that people know about? Peter
