Power. Put to perfect use in a single cylinder.
An engine of progress. Right from the day it was launched, this engine was an absolute sensation. The first serial single-cylinder
to have an electronic injection system and catalytic converter and it is still setting standards in its class. Now it is causing a fresh
sensation. The dual ignition system, already enthusiastically welcomed in the Boxer engine series, is now also being incorporated
into the latest single cylinder generation. Powerful output is already available at 2,000 rpm and thanks to the compensation shaft,
the single cylinder develops its power gently but with determination and from 4,000 rpm is nothing less than a power station.
This results in excellent acceleration and engine power.
Together with the Two Spark dual ignition system, the BMS-C II engine management system, with its quintuple calculation speed,
considerably reduces fuel consumption and exhaust emissions. At high speeds this makes quite a difference. Cruising at 75 mph
the reduction compared to the predecessor amounts to 0.7 l to 4.3 l per hundred kilometres. And the torque curve has been
optimised into the bargain while meeting the EU3 emissions standard with ease. The 50-bhp (37-kW) single-cylinder engine
is also available in a reduced power version with 34 bhp (25 kW), for new riders.
