DescriptionThe whole story▼
Hinter der Scheibe einer M 1000 RR geduckt, blickt der Fahrer direkt hinunter auf die obere Gabelbrücke, die Klemmen der Lenkerstummel und die Lenkkopfmutter. BMW hat dieses Blickfeld fast überall bis aufs letzte Gramm durchkonstruiert, nur bei der Mutter nicht. Die Gilles ACMA ersetzt sie durch ein gefrästes Teil in Schwarz, Blau oder Rot.
Die wichtigsten Merkmale
- Gewinde M28 x 1.0
- Nicht für Hinterrad- oder Schwingenachsen (laut Gilles)
- Ausschließlich als Lenkkopfmutter konstruiert
- Aluminium 7075, eloxiert
- Patentierte Verdrehsicherung mit Stiftverriegelung, übernommen von der ACM-Achsmutter
- Laut Gilles keine Eintragung erforderlich
Farben vom Fahrerlager bis zum Podium
Gilles listet die ACMA für alle Typen der M 1000 RR, von der SM99 von 2020 bis zur SR99 ab 2025. Viele dieser Motorräder fahren in Club- und nationalen Rennserien, manche in eigenen Teamfarben; zu ihnen passt eine schwarze Mutter, während Blau oder Rot zur M-Lackierung ab Werk passt.
Straßenzulassung
Für die BMW M1000RR braucht die ACMA laut Gilles keinerlei Genehmigung. Es muss keine Bescheinigung mitgeführt werden; mit dem vorgeschriebenen Anzugsmoment montieren und danach die Lenkung prüfen.
Lieferumfang
Eine einzelne ACMA-Mutter aus Aluminium 7075, Gewinde M28 x 1.0, Farbe nach Wahl.
Montage
Nach der Montage den Lenker von Anschlag zu Anschlag drehen und die Gabel bei gezogener Vorderradbremse vor- und zurückwippen: kein Spiel, keine schwergängigen Stellen. Fühlt sich etwas anders an als vorher, den Lenkkopf prüfen lassen.
