Beta Enduro RR 2016

They pursue continuous growth through quality and a commitment to sport and innovation, which turns out to be very beneficial in practice. After last year's "shrinkage", that is, downsizing the four-stroke models to improve the handling of the bikes, they also came as a significant surprise this year. The main innovation is oil injection in two-stroke engines and fuel injection in all four-stroke engines. In the world of two-stroke engines, both in motocross and enduro, oil still mixes with fuel before it enters the fuel tank, and Beta has taken a step further and developed electronically controlled automatic oil injection that regulates the amount of fuel. oil depending on engine load and speed. This provides the two-stroke engine with the perfect mixture of gasoline and oil in the combustion chamber, which also provides up to 50 percent less smoke or blue fog from traditional two-stroke engines. This system was first used last year on the Beta Xtrainer 300 recreational enduro model and, given the excellent response from the owners, they decided to implement it in sports enduro models as well. Now there is absolutely no need to worry about whether you have correctly installed the gasoline and oil and whether you have forgotten to add oil to the gasoline. To the oil tank next to the air filter, simply add oil for the mixture, which is enough for three full fuel tanks. Although it is now also translucent, you can easily check the fuel level. So you no longer have to count and shave your head at a gas station, how much oil to top up with each refueling. Thanks to this system, the 250 and 300 cc two-stroke engines also perform better, providing a longer service life for the already highly reliable, low-maintenance engines. The Beta 250 and 300 RR also feature new engine electronics that increase performance at higher rpm, where in the past there has been some criticism for underpower while maintaining a traditionally moderate and smooth power curve, which means excellent rear wheel traction throughout the engine. range of speeds. Therefore, both two-stroke models have extremely unpretentious engines with a huge net power that the hobbyist can handle, and at the same time, the professional will be satisfied with the maximum power. The most mechanical changes were made to the 250 cubic meter engine, which completely changed the head and geometry of the exhaust and exhaust. There are also some innovations in the area of ​​the frame, which is more durable and provides better handling under loads. In the enduro test that was prepared for us in Italy, the two-stroke engines turned out to be extremely lightweight, precisely maneuverable and, above all, with a very tireless ride. After a few clicks of the front forks (Sachs) adjustments, the suspension also proved to be very good on dry and hard soil, a mixture of stone paths, meadow paths and forest paths. We have no comments on enduro use, but for serious competition and motocross trail riding, the Beta offers a special, more exclusive racing replica with the biggest difference being the race suspension. But if you're not quite Micha Spindler, who has achieved several successes in the toughest extreme enduro races with the Beto 300 RR Racing, you don't even need this suspension. Although the popularity of the Beta 300 RR enduro special is still growing sharply and production in Slovenia and abroad is not keeping pace with orders, it should be noted that the introduction of the fuel injection system in all four-stroke models was a pleasant surprise. The suspension and frame innovations are the same as in the two-stroke models, but a little more attention has been paid to the camshaft and intake enhancements in the 430 and 480 models (to improve torque and power). All engines now have aluminum bolts to reduce weight. Last year, our test driver Roman Yelen praised the 350 RR model, which was the first to be introduced into the system, indicating that the system is working well. The same is true for the rest of the four-stroke engines marked 390, 430 and 480 RR. Last year we presented a somewhat unusual label in detail, so this time only briefly: we are talking about optimizing the volume, power and inertia of rotating masses in four-stroke engines. At the expense of slightly less power, the bikes are easier and more precise to handle, and above all, they are less tiring on long enduro rides. If someone thinks they need a lot of "horses", they can still get their hands on the "arm extension", the Beti 480 RR and, in our opinion, the Beta 430 RR (that is, the one that belongs to the 450cc class. ) is the most versatile enduro motor on the market for most enduro riders. It is not devoid of power, but at the same time it offers exceptional driving performance.
