According to my Official Buell Factory bodywork catalog, the S2T was 1996 only. However it looks like the saddlebags were the same for the S2T and S3T for all years.
not so; S3 bags can be expensively retrofitted to an S2, but the bags mount quite differently. S2T bags have the nifty little Dzus fasteners, while S3's, as I recall, bolt on.
