Lot Details
1927 BMW 493cc R42
1928 BMW 494cc R42
Frame no. 15230
Engine no. 45420
Launched in 1923, the first motorcycle to be sold as a BMW - the R32 - featured a 494cc, twin-cylinder, sidevalve engine having horizontally opposed cylinders, and this 'flat twin' layout would forever be associated with the marque. Setting a pattern that endures to this day, the first BMW motorcycle was relatively expensive but superbly engineered and constructed, while the quality of finish was of the highest order. Before long BMW updated its original tourer, which in 1926 became the R42, gaining a redesigned and more powerful engine boasting detachable alloy cylinder heads and cooling fins set at 90 degrees to the cylinder axis. The engine was set further back in the duplex loop frame, which improved weight distribution and enabled straight front down-tubes to be used in place of the curved ones seen hitherto. The braking too came in for attention: the old block-and-pulley type rear brake being replaced by a drum on the driveshaft gripped by external contracting bands. Electric lighting was still regarded as an 'extra' and would not be standardised until 1928. R42 production lasted for just two years and today this rare Vintage-era BMW is among the marque's most desirable and sought after machines of the period.

Information supplied by the BMW Group Archives states that this example consists of a frame from an R42 delivered to the German dealer Jakobi in Nürnberg on 23rd April 1928 while the engine was in an R42 delivered to the Swiss dealer Drenowatz in Zürich on 22nd March 1928.

Finished in BMW's traditional black with white coachlining, this immaculate machine was restored in 2010 and purchased by the current vendor from an Italian private collector in Trevisio, Italy in May 2011. The optional electric lighting is a particularly noteworthy feature of this particular R42, which comes with an instruction manual. There are no registration documents with this Lot.

Als Nachfolgerin des 1932 vorgestellten, ersten BMW-Motorrads, der R32, kam die stark verbesserte R42 1926 auf den Markt. Der stärkere Motor verfügte bereits über abnehmbare Zylinderköpfe. Darüberhinaus wurden deutliche Verbesserungen an Rahmen und Bremsen vorgenommen. Aus dem BMW-Archiv geht hervor, dass der Rahmen am 23. April 1928 an die Firma Jakobi in Nürnberg geliefert wurde, während der Motor zu einer R42 gehörte, die im März 1928 an den Schweizer Händler Drenowatz in Zürich ging. Im Jahr 2010 restauriert, wurde die Maschine vom gegenwärtigen Besitzer, im Mai 2011, von einem Sammler in Treviso, Italien erworben. Die seinerzeit nur auf Sonderbestellung lieferbare elektrische Beleuchtung, ist ein besonders bemerkenswertes Detail. Die R42 wird mit einer Betriebsanleitung, jedoch ohne Fahrzeugpapiere angeboten.
