If I'm not mistaken that's a XB9 right? I'm looking for an XB12.
Towards the end, there was an XB12SX. I dont know if it was 2009 or 2010 when it was around. You said you were looking for an XB12SS. To me the longer wheelbase of a SS (or Uly or STT) is much more of a preference (to me) over the shorter wheelbase models. Having owned both, I probably wont own a short wheelbase one again. Nothing wrong with the short wheelbase XB's , I just prefer the longer wheelbase and slacker HTA of the "Long" bikes. I'd rather own a XB9SS (they didnt make one) or an XB12S anyday. I still regret selling my 06 XB12SS.
Speaking of faster isn't always more fun. A LOT of people who have owned and ridden both bikes will say the 9 is more fun than the 12... myself included. I generally dont ride fast or even aggressively... just for some people the "lack of power" and smoothness compared to a non-Harley bike is a bit of a culture shock for someone who is used to Asian or Euro bikes. Don't get me wrong, I love my Buells, but there are reasons why the "other guys" tended to out sell them. As far as sounding great, a Buell with an aftermarket pipe sounds great, but so does an aircooled Duc with Termis.
Here is a breakdown of the model years I found doing a search on here:
Pre '08 = Original ECM's & Oil Pump Gear
'08 - Later = Newer "Learning" ECM's & upgraded Oil Pump Gear.
(Some '07s will be included in the "Post '08" category. And the "Learning" ECM's will generally only compensate for either an upgraded intake OR exhaust. They have trouble with both and may require a custom map just like the earlier years.)
2009 = ZTL2 8 Piston Front Brake (XB12 Models)
2010 - Current =
- Fuel pump & fuel pressure sensor similar to the 1125's.
- Front & Rear New style LED turn signal.
- 30mm rear wheel bearings
- 3 bearings and dust seals. (One bearing on brake side and two bearings on sprocket side.)
- New tools are required to remove and install the new bearings.
- Axle & Wheel hub changes due to the new bearings
- Front Cylinder O2 sensor has been added.
- Wire harness changes. (Addition of fuel pressure sensor wire and front O2 sensor wire.)
- For XB12R models, the rear sub-harness is now part of the main harness.
- Fuel pump break-out location change
- JST Connectors on tail light & license plate light.(XB12R ONLY)
- Updated oil check procedure
- New Fan logic driven by speed and temperature
- Battery tender connector built into harness
Some of the guys who have ridden both the ZTL and ZTL2 brakes swear by the ZTL2. I've only ridden the ZTL (ok, I had a ZTL2 on my 1125CR) and its always done great for spirited street riding.
IMO, the 3 bearing rear wheel is probably the best reason to choose a 2010 model. However, this can be retrofitted to an earlier bike if you really want to.
My $0.02. Hope this helps.
