Identify the engine upgrade before comparing Stage kits

This category contains different levels of engine work. A shared Stage name does not mean the same starting displacement, cylinder heads, camshaft or calibration. Compare the exact kit contents with your existing engine and the riding character you want.

Select your year before choosing a kit. The 117-to-131 film applies to 92500146, not every 131-labelled or Stage IV product in this all-years grid.

A cam-chest upgrade is a different purchase

The catalogue also places Stage II Bolt-On Power Kit 92500075A here. Its description specifies opening the cam chest and a power delivery aimed at the middle and upper rev range. Do not read the category name as a promise that this kit includes larger cylinders or the complete Stage IV combination. Use its own parts list and installation requirements when planning the work.
