Thanks, Jürgen, for the detailed information!

I lacked a bit of patience and had already ordered an RK ZXW chain, a JT rubber-damped front sprocket, and an Esjot rear sprocket from Carpi Moto in Genoa before your post. Had I waited, I would have used your suggested source, kawaschrauber.de, which would probably have allowed me to save on the customs fees for imports into Switzerland by using a parcel forwarding address in southern Germany. At least Carpi Moto deducted the VAT.

In addition, unlike the MVXZ2, the ZXW doesn’t come with a screw-type master link, so I’ll have to rely on my bike shop for the installation.

Patience is a virtue.

Hi Pard,

Thanks for the valuable information and for pointing me to that thread. I completely missed it in my searches.

Cheers,

Hi everyone,

I ride an Energica EsseEsse9+ RS with the EMCE motor and notice a strong jerking/surging sensation under partial load at around 80 km/h / 50 mph. The effect is not only felt as a vibration or oscillation, but can also be heard acoustically as a changing frequency.

The issue does not occur under full acceleration or during regenerative braking, but mainly when maintaining speed with light throttle. The vibration/oscillation is strong enough that my Givi tank bag visibly swings back and forth. Uneven road surfaces seem to amplify the effect.

Could this be caused by uneven chain stretch or a tight spot in the chain? A manual check of the chain, without measuring tools, did not reveal anything obvious. Or are there other known causes on the EsseEsse9+ RS / Ribelle RS / EMCE bikes that can produce this kind of partial-load surging?

Any suggestions on what to check first would be much appreciated.

Thanks!

I wanted to share a potentially useful finding for owners of the Energica Eva, Eva Ribelle and EsseEsse9 in Europe.

Given that the original Energica LED indicators still are unavailable as spare parts, finding a suitable replacement is somewhat difficult.

It is already known that the LED indicators used on certain model years of the Aprilia Caponord are identical to those fitted to the Energica Eva family. However, these Aprilia-labelled parts usually cost around €45 each.

What may be less widely known is that the LED turn indicators used on the Fantic Caballero 700 and on the XMF/XEF 125, model years 2023–2024, also are identical. In Germany, these Fantic indicators can be ordered for around €20 each from Fantic parts suppliers.

This is relevant mainly for European Energica models, because US-market Energicas were equipped with conventional bulb indicators rather than LED indicators. If LED indicators are retrofitted to those bikes, additional resistors would be needed so that the electrical load remains within the range expected by the bike’s electronics.

One important practical note: some soldering is required for the Aprilia as well as the Fantic indicators. The easiest option is probably to reuse the cables and connectors from the original defective Energica indicators. Alternatively, suitable Molex connectors can be ordered separately. The connector type appears to be:

Molex 18–24 AWG, Standard .062” pitch / 3.68 mm, 2-circuit connector

Depending on the side of the bike, you may need either the male connector on the left side or the female connector on the right side. However, these Molex connectors are relatively expensive and quite fiddly to work with, so reusing the original Energica indicator cables may be the more practical solution.

Kudos to @jotjotde for the valuable information on the Molex connectors!

From what I could find, the "brick" of an EVSE usually contains the control pilot signaling, ground-fault protection, current and temperature monitoring, relays, and the basic safety logic. So its design and build quality is indeed safety-critical.

That's why I'm more than a bit uneasy about ultra-compact designs where everything is packed into the J-plug. Beyond heat dissipation and long-term reliability, I also wonder how well fault protection can realistically be implemented in such a small space - especially AC ground-fault detection and DC leakage detection, which seem to be essential to avoid blinding upstream GFI/RCD devices. Without independent certification (CE, etc.), this approach seems to carry non-trivial risks.

Hi jotjotde,

Thanks, but I have a brickless brick in mind. Yours does look fairly compact indeed, but it still takes up more space and adds more weight than a truly brickless EVSE. The unit offered on AliExpress appears to do exactly what I am looking for; however, given the lack of documentation and real-world user experience, I do not feel comfortable trusting it.

Hi everyone,

Does anybody here happen to own one of these Romada 3.5kW/16A Compact Type 2 chargers? (https://aliexpress.com/item/1005010017541800.html)

It seems to be very compact and lightweight—potentially a good solution for traveling in areas where fast chargers are scarce. However, I'm unsure if it’s legit or compliant with necessary safety standards. I can't find any tests or reviews and there's no documentation at all from the manufacturer or seller, just the few pictures on Aliexpress. Despite the low price, I’m hesitant to buy one due to the risk of bricking my SS9.

Any experiences would be greatly appreciated.

Best, Urs
