This is the only 2-stroke engine had managed to get the Euro5 certified

Unique ONES When we hear about the 2-stroke engine, we usually immediately imagine an engine with a crisp sound with a puff of smoke. Right, as it is known that 2-stroke engines often produce high emissions which are said to have a bad impact on the environment and health. So that then makes many automotive manufacturers have to change their business strategy by no longer producing 2-stroke engines.

Meanwhile today, we enter an era that requires motorized vehicles should be had minimal or even zero pollution, and as we could be seen today, there are many countries in the world had been awared and then paid great attention to the air quality, as one of the reasons why 2-stroke engines gait rarely seen milling around on the streets.

But now the 2-stroke engines seem to have second chance, because reportedly, there are manufacturers who are able to make 2-stroke engines could be passed emission tests and get the Euro5 certified. Even, it could be said as the only 2-stroke engine that has passed the Euro5 emissions test at this time.

The manufacturer that produces the 2-stroke engine in question is Langen Motorcycles, a British motorcycle manufacturer under the Vins company who is not join in the other to leave the production of 2-stroke motorcycles. Even they can be gave the hope to revive the glory of 2-stroke motorcycles by birthing the cool engine innovation. For the first time, the Langen's 2-stroke engine can get certified and pass the emission test amid to the strict of the Euro5 regulations.

The machine mentioned above, which later called as the Langen Deucinquanta, (the Italian for 'two fifty' reffered to the engine displacement). After the Euro5 certification obtained, certainly will make motorcycles that use it as a drivetrain can be produced and rode legally in Europe. As quoted from Visordown, the Langen' machine is featured with a design and performance cannot be underestimated at all. And reportedly, this machine offers specifications and design like a MotoGP racing machine.

But how did Langen Motorcycles come up with this eco & health feiendly 2-stroke engine? Of course this cannot be done in a splash without any significant calculations and innovations. It can be said that Langen Motorcycles has made a bold and brilliant steps when making changes to its engine system, and reportedly, the work is carried out by a former Ferrari technician recruited by Langen Motorcycles.

Well, this British manufacturer made changes to the design in such a way that the engine is able to produce low emissions. And the design changes include changes to the feature of the shaft being rotated in the opposite direction to increase performance, besides that they also implementing a direct injection system.

Meanwhile, this direct injection mechanism is carried out by the injector located in the cylinder head by spraying fuel directly into the combustion chamber which had filled with the air supplied by the intake. This system is considered successful and able to increase combustion efficiency, increase fuel economy and reduce emission levels.

Langen Motorcycle's engine is claimed to be capable of producing power of around 75 hp at 11,700 rpm with 45 Nm of torque at 11,700 rpm. (Picture from: Visordown)

Then the Langen engine is a 2-stroke V-twin 90 degree engine with a capacity of 249 cc, by using fuel injection supply. The engine is claimed to be capable of producing power of around 75 hp at 11,700 rpm with 45 Nm of torque at 11,700 rpm. Although on paper the performance figures are not impressive in today's era, in which the superbike engine has been able to spew power up to 200 hp, but it should be remembered that the Langen engine capacity is only a quarter liter.

And the motorcycle is built on a tubular model chassis so no wonder if the weight of this motorcycle is very light at 114 kg and has a power-to-weight ratio of 660 hp per tonne. So that with a burst of engine power of around 75 hp, it is able to carry it up to a top speed of 225 kph. Interestingly, the cafe racer-style motorcycle has undercowl at the bottom.

Next, how does it look? As previously mentioned, Langen Motorcycles appear in a typical cafe racer style which is equipped with a round headlight, exotic tank, and a sharp stern shape typical of the cafe racer style. Then this motorbike uses Ohlins' 43 mm telescopic front suspension and the legs use a pair of spoke rims and is wrapped with Dunlop Classic TT100 tires measuring 120/70 front and 150/60 rear.

And for those of you who are interested, the Langen Two Stroke is offered with a starting price of £28,000, although as is the nature of bikes such as this, the machine can be tweaked to the owner’s desired specification. And the completed machine will be on display prestigious Salon Privé later this month, while the official unveiling will take place at Blenheim Palace from the 23rd – 26th September.😃
