[Bearbeiten] Geschichte

[Bearbeiten] Entwicklung

Das Parallelmodell R 42 ist das einfachere Tourenmodell mit Seitenventiler-Motor im gleichen Rahmen.

BMW führte mit diesem Motorrad das Baukastenprinzip weiter. Fahrwerk und Getriebe mit Grundmotor waren weitgehend baugleich; die Differenzierung nach Sport- und Tourenmodellen wurde durch kopf- oder seitengesteuerte Zylinderköpfe und Zylinder umgesetzt.

[Bearbeiten] Technik

Es war um 2 PS kräftiger und ein wenig leichter geworden. Das erfolgreiche Bauprinzip der R 32 war ansonsten gleich geblieben:

  1. längs eingebauter Boxermotor, das heißt, die Kurbelwelle liegt längs, Zylinder quer zur Fahrtrichtung. Dadurch wird die Kühlung verbessert.
  2. Antrieb des Hinterrades mit Kardanwelle,
  3. direkte Verbindung zwischen Lenkkopf und Hinterachse.

Der Motor hatte erstmals eine geringfügige Schalldämpfung. Die Vormodelle entließen die Auspuffgase im Wesentlichen ungedämpft ins Freie.[1]

[Bearbeiten] Fahrwerk

Das Fahrwerk ist das gleiche wie bei der R 32: ein Rohrrahmen ohne Hinterradfederung, die Vordergabel ist eine gezogene Kurzschwinge mit Blattfederung.
