If the title says 89 than it is not an SE. The SE came out in October 89 with all the other 90 models but the title would say 90, just like cars, bikes come out the end of the prior year but are called 1 year later model. The SE had a lot more than just 2 tone paint.
The SE had two-tone paint, trunk spoiler/light, windscreen vent, lighted handlebar switches, adjustable passenger footboards and foot warmer vents that looked better than they worked. Does your bike have all of these
Do you have a picture you can post? If not what color is the bike? Actually the second color was sold as decals that you could apply to make an Aspencade look like an SE.
