'03 models had recalls for the wheel bearings failing pre-maturely
Pre '06 =
3.7 gallon fuel tank
'06 - Later =
3.82 gallon fuel tank - (SS Model =
4.4 gallon fuel tank)
(This was due to earlier years having an air "hole" through the frame, as pictured below. Of course the latter models don't.)
Pre '05 = 41mm forks
'05 - Later = 43mm forks
Pre '05 = DDFI fuel injection
'05 to '07 = DDFI2 fuel injection
'08 - '10 = DDFI3 fuel injection
Pre '04 = Original belt system
'04-Later = Upgraded belt system
(Earlier years had some reports of pre-mature breaking belts)
Pre '05 = Original Kickstand components
'05 - Later = Upgraded Kickstand components
(Earlier years had reports of failures resulting in dropped bikes.)
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. The newer ECMs also had a larger Closed loop ("learning) range and will generally only compensate for either an upgraded intake OR exhaust mod. Some have trouble with both mods and may need a custom mapping.)
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
