Bin sehr zufrieden. Trage den Protektor in meinem alpinestars Einteiler. Er passt hervorragend. Sehr schnelle Lieferung, aber das ist bei FCMoto ja nichts Neues.

Buena calidad, ligero, versatil

La espaldera encaja en la chaqueta de manera precisa. Ademas es compatible con varias chaquetas de la misma marca, por lo que es intercambiable y versatil.

Gut, aber es geht noch besser

Der Nucleon Flex ist ein guter Protector ( bei mir Größe L), der allerdings in den Alpinestars Jacken ( Astars Bogota Größe 3XL) sehr stramm sitzt und die Jacke recht steif macht. Der Bewegungkomfort sinkt merklich in einer Textiljacke.Daher ziehe ich zwei Sterne ab. Der Nucleon Plasma Full Back ist wesentlich komfortabler und passt auch viel besser in die Protektorentasche der Jacke.

bueno

solo que no es compatible con las chamarras las espalderas son uy largar y no quedan sugiero buscar otra opción de protección compre la chica y mediana y ninguna cabe en una chamarra dry star
