Ah the great 2002 SE Mystery. Some say as few as a couple Hundred, I have heard 1 per dealer. But really, Tampa area Population is roughly 3 million, and just riding around here I have seen one other in person and I know HayabusaMan has one as well. So there are a minimum of three In Tampa alone, Plus Blas32 up north. So lets say there is one made per every million in human population. (NOT SCIENTIFIC) the US Population is roughly 300mil, so we could roughly say there is at least 300 of the buggers out there.
Suzuki isn't saying though, and they were offered as a sales incentive in 2002 so a dealer could have ordered as many as he thought he could sell. But this could also mean that Many Dealerships never even had one. Where I bought mine is a prime example, they had never heard of the 2002 SE until I went in there bugging...
Now I have heard that the SE was created midyear as a way to celebrate having sold 12,000 Hayabusi since it's creation. But who knows... Suzuki isn't saying for whatever reason...
