The Royal Enfield 570158/B UCE Mainshaft Sub Assembly is a genuine OEM transmission component used inside the UCE 5-speed gearbox.

Royal Enfield parts data identifies 570158/B as “UCE, MAINSHAFT SUB ASSY.” The mainshaft works with the gearbox gears, selector forks, bearings, spacers and related transmission components to transfer engine power through the motorcycle’s manual transmission.

The earlier part number 570158 has been superseded by 570158/B in Royal Enfield parts data.

This is an internal gearbox component and should be replaced only after confirming the exact gearbox configuration and part number.
