DS900X 2025 - Factory firmware (HMI 1.5 baseline)

Source: owner reports. Version strings come from owner observations. Claimed changes, remedies, compatibility and update procedures are community reports or interpretations, not Voge-verified release notes or instructions. A confirmed version observation does not confirm the associated compatibility or fix claims.

Confirmed factory firmware loadout for an earlier 2025 production DS900X, reported by an owner on the Voge 900 DSX Facebook group with a full Menu → System → About screenshot before they applied the 1.8 update.

What's on the bike

Two components changed between 1.5 and 1.8:

• HMI stepped from V1.5 to V1.8 (three-point bump).
• MCU SW stepped from -07 to -10 (also a three-step bump, suggesting -08 and -09 may have existed as intermediate releases we haven't seen documented).

The HW and OS strings are identical across both - confirming that this is a software-only update, not a dashboard module swap, and the underlying OS is stable across the 1.5 → 1.8 release.

How this fits in the DS900X firmware generations

The DS900X exists in two distinct hardware generations that aren't cross-flashable without an HMI module hardware swap:

If you're trying to flash 4.x onto a 2025+ bike (or vice versa), it won't work and may brick the dashboard. Voge does not publish this distinction explicitly - it's been pieced together from owner reports on the FB group thread "How can I install the last firmware on the 2025 model?".

What 1.5 was like (pre-1.8)

Owners running 1.5 reported several issues that were later fixed in 1.8:

• Jerky throttle below 2,800 rpm in Road and Sport modes
• Rough cold-start idle
• Unstable Carbit Ride app connection dropping intermittently
• "False neutral" sensor errors causing brief jerking at startup
• Notchier Quickshifter upshifts (still drivable, just less polished than 1.8)

Owners report these as fixed or improved in 1.8 - see the HMI 1.8 entry for the collected owner-reported changes.

What you should do

If your DS900X shows HMI SS621X15-HMI-V1.5 and you're experiencing any of the above issues, the 1.8 update is a clear quality-of-life improvement. Two paths:

1. Voge dealer - bring the bike in. Dealer firmware updates are normally free under warranty. This is the safe path.
2. OTA via Voge Global app / Carbit Ride - some 2025+ bikes can pull the update directly. Procedure varies by region and isn't always available; ask your dealer if it's been enabled for your VIN.

What we'd still like to know

• Full quad-version readout for an as-shipped 1.5 bike (HW + OS + HMI + MCU SW from the Menu -> System -> About screen). Send yours in if you're on 1.5 and haven't updated yet.
• The OS / MCU version paired with HMI 1.5 - we'd expect something earlier than the SS621X15-OS-V2.3.2 / SS621X15-10 seen with 1.8, but no confirmed data point yet.
• Earliest production date that shipped with 1.8 from the factory (vs needing a 1.5 -> 1.8 update at dealer).
