I've had two Sportsters. Bought a new 1984 XLX1000 that year, and recently had a 2008 XL883. I understand they have dropped the XR1200 now. Too bad. I worked at Destination HD in Tacoma, Wa. for five years, so am a bit out of touch now. I much prefer an XL with the longer "standard" length suspension. My two XLs didn't have much of a scraping of parts while cornering problem. A co-worker with a Nightster tried following me on the way to work one day on a nice curvy country road, and could not stay with me due to lack of cornering clearance. I was 58 at the time and he couldn't believe how far I leaned in the corners and the speeds I went. All the Sportsters now have lowered suspension since the fine XR1200 and XL883R and XL1200R have all been dropped for the US market. These shortened models would have to have longer shocks and longer fork tubes installed. I think it's a dam shame, as a Sportster CAN be fun on a twisty road. Some prefer the older ridgid mount models due to their lighter weight, which can be as much as 75-85 pounds difference. Yes, they vibrate more, but depending on the bike and how it runs, some don't find the vibes that bad. That's why many "cafe" bikes that are Sportsters use the pre-2004 models. There should still be parts where you can convert your 883 to a 1200 using dished pistons available from HD. This way you can reuse the 883 heads. Your converted XL you will find, will be faster stop light to stop light than a factory 1200 as the gearing is lower on an 883. If I converted one I would stay with the 883 gearing, as my 2006 ran just fine at freeway speeds and got very good mpg. If you don't mind the shortened XLs, you might take a look at the "Superlow". It comes with radial tires and some nice radial wheels, and a bigger 4.5 gallon tank. I love the looks of the 48, Iron, Nightster, etc, but after riding the two that I owned, I don't know if I could live with a Sportster that shoots showers of sparks in the corners. I also don't like forward controls, as they can be another problem in the area of cornering clearance. I think a good, used "R" model would be hard to beat, and they made them before they went to the rubber mounted Sportsters also. They have dual front disk brakes, nice flatter handlebars, and longer suspension. The tank on the 48 is too small for me. I really enjoyed the two Sportsters I owned and wish I would have kept my 2006 and paid to have it shipped to the Big Island.
