Not on holiday,
@Arminius, just fashionably late. I see you covered for me admirably with Google's help, and the instructions are essentially correct, so credit where it's due.
One small addition worth flagging for
@dikkieduk: if the performance update doesn't appear in the Flow app straight away, community experience suggests it can be a multi-step affair. Some owners have found they need to update the Flow app itself first, restart their phone, then update the bike firmware, and
then a separate performance update option appears. If after all that the 100Nm slider still doesn't show up, force-closing the app and reconnecting to the bike has been known to trigger it. And if none of that works, a dealer with the Bosch diagnostic tool can push it directly.
The "Race" branding on the motor shouldn't make a difference here, the CX Race (BDU384Y) is the same 100Nm/750W update path as the standard Gen 5 CX. But KTM's naming conventions can be confusing, so if
@dikkieduk can confirm the exact drive unit code (visible in the Flow app under bike details), we can verify it's definitely the Smart System variant that's eligible.
EDIT: @Arminius reports The MACINA PROWLER EXONIC with Gen4 Race has 85Nm and cannot be updated to 100Nm. Only the newer MACINA PROWLER EXONIC CX-R with Gen5 Race (100Nm) supports that specification. The user must own the Ge. Not yet independently verified — take with a pinch of salt.
Worth noting based on
@dikkieduk's own experience: running the 100Nm setting appears to carry a thermal caveat. Overheating has been reported after around 20km in race mode, which suggests the 100Nm adjustment may not be safely sustainable on all bikes or in all conditions. Something to factor in before committing to that setting full-time.
EDIT: Corrected to reflect that 100Nm operation can cause overheating issues — dikkieduk's bike experienced this after ~20km in race mode, so the adjustment being technically available doesn't necessarily mean it's problem-free in practice. Thanks
@dikkieduk for the heads up.
Nevertheless updating via app should be working. Make sure having full batteries on bike and phone as well as a stable internet connection (preferably WLan). Have done it a couple of times on my eMTB Gen4 and the trekking bike Gen5 (not using the 100Nm) with absolutely no issues. I start wondering if I will skip upcoming updates as there is not much really new / usefull coming anymore.
