The 1125 has a few quirks out of the box. But they are easily corrected under warranty at no charge to the owner. Long term reliability seems to be good. --Reflash the ECM - runs smoother, runs cooler, makes a bit more power. --Clutch cover tends to weep a small amount of oil out of the vent hole (small amount= a drop every thousand miles or so). New version of the clutch cover is available under warranty. --The Low Fuel Light can come on faslely at low temps, say under 45 degrees, it goes off as the motor reaches operating temp. The fix is to replace the Instrument Cluster with one with an updated firmware version. Free under warranty. --The only ongoing issue seems to be stator failures on 09s. HD has replaced (not recalled) the charging harness with one that seems to extend stator life. Perhaps they will realease an updated stator that solves the problem completely. *Not all 1125 have these issues, but these are the ones that have been mentioned with some regularity on the the Buell forums. All in all, I am happy with my 1125. The handling is top notch & the power delivery is quite linear.
