I received the Mustang Sport Touring seat (#75733) and put it on my '03 1200S three or four days ago. It's truly outstanding......all the difference in to world, both front and rear, and looks good. Best money I've spent so far.
My local non-Harley Harley shop just punched the stock mufflers, re-jetted the carb and put a K&N air filter in the stock box. Sounds great, runs a little better. It's gettin' there......
IMO, any stock Sporty seat is a total waste of petrochemicals! They may look good, but provide virtually zero support/comfort! I bought a Mustang for my second Sporty and kept it when I traded the bike in, to "retrieve" a Ducati 900FE I had mistakenly traded. At any rate, the Mustang went on my '02 1200 std. before I rode the bike home. What a difference! I can and do run her for 150 mile rides at @ 75-80 mph on 2 lane backroads. The workmanship and quality of the Mustang are supurb; much better than the Corbin I had on my Kaw ZX12R.
I don't often buy aftermarket parts, but that saddle was the best $$$ I've ever spent on a "part". DFO
