Not entirely correct.
Other than the sweet paint scheme, the 2002 M750s i.e. (vs M750 i.e.) had new aluminum swing arm and headlight fairing, increased ground clearance, and CF side panels and heat guards.
It was also only sold in the USA.
Corrected: A M750S i.e. with gray paint.
Agreed that it's sweet, it was one reason I bought my S4. Also why I love the 2002 748s in the flat gray with red wheels.
