Danish company Lauge Jensen is the first motorcycle manufacturer in the world to pass the new EURO4 emissions regulations.
The EURO4 emissions laws, implemented from 1st January 2016 to 31st December 2020, are being introduced to drastically reduce the amount of harmful exhaust gases produced by motorcycles. These forthcoming mandatory rules for all manufacturers are almost 50% more difficult to pass than the current EURO3 standard.
The passing of EURO4 came after two years of continuous work, and for Lauge Jensen to achieve this ahead of the rest of the world’s motorcycle manufacturers is quite an achievement. Lauge Jensen was aiming to improve the American S&S motors (Wisconsin, USA) it uses at the heart of its bikes.
The Danish based company, established in 2008, designed its own piston, camshafts, exhaust and catalytic converter for the internals of the 1,800cc V-twin engine, along with the software to programme the fuel injection system.
Lauge Jensen’s research and development team saw the potential to fine-tune its new engine specification – dubbed ‘1-Eleven Squarehead’ – on its in-house dynometer, to meet the stringent tests. At first, meeting the restrictions of the EURO4 regulations impacted drastically on the power and noise characteristics of the bike, but the Lauge Jensen team aimed to restore the ‘feel’ of the engine. The end result, of course, is improved fuel consumption.
On achieving the EURO4 approval for its engine, Director of Development, Uffe Lauge Jensen commented: “At Lauge Jensen, we think of the engine as the ‘heart’ of a motorcycle and, it is certainly important to have a strong, healthy heart! Being first with EURO4 may not be a primary concern for some of our customers, but it will give them the reassurance that they own a fantastic and personal motorcycle, which is future-proofed, and ahead of the rest in its low emission output.”
“A Lauge Jensen is not about living up to today’s standards, but to those of future, and showing the world that this little Danish company creates bikes for the world that are mean, lean and green!” he added.
The ‘1-Eleven Squarehead’ will be fitted as standard to 2014 Lauge Jensen motorcycles.
