I fix and renovate oldish bikes as a hobby, and I'm always cannibalising some to rebuild others, so it was nice to see these on Vine.
The magneto arrives well packed, in a strong box and wrapped in greaseproof paper (and a little keyring too, nice touch).
It's the exact clone of an older RSV4 mag coil, both in size, cable setup and function, at a fraction of the prize of a rather hard to source original piece, especially on a bike this rare, and I'd say way more reliable as not manufactured decades ago.
A really nice find, I know I'll be bookmarking this brand
Ho acquistato questo statore come sostituto del modello originale montato sulla Aprilia RSV4 del 2012.
La qualit�� del prodotto �� elevata: le dimensioni e le caratteristiche tecniche corrispondono perfettamente a quelle del componente originale. L��installazione �� stata semplice e veloce, senza alcun tipo di difficolt��, grazie alla piena compatibilit��.
Una volta montato, ha funzionato subito senza problemi: nessuna spia di errore, n�� malfunzionamenti del motore o dell��impianto elettrico.
Si tratta di un ricambio ben realizzato, affidabile e offerto a un prezzo competitivo.
Lo consiglio a chi cerca un��alternativa valida all��originale, senza compromettere la qualit��.
This is obviously not an OEM, however it feels great quality. I had it installed by a friend and no issues so far but can't comment on longevity
