240 USD is quite a lot. Still, I'd be okay with that if it worked perfectly from the start. With two failures for two attempts, Ribelle (2022) and Experia, it doesn't look like they even tested the their product with the models they promise it works with.
I contacted Marchel (Electric Motorcycles Nederland) and asked about their cruise control relocation kit. At 199 Euro it costs pretty much the same, but given their expertise, I assume it will work from the start.
