We passed: 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 shrinking last year, i.e. reducing the volume of four-stroke models to improve the handling of motorcycles, they also turned out to be 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 gives the two-stroke engine 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 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 at a gas station how much oil to add with each gas station.
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 revs, where there has been some criticism in the past for lack of power while maintaining a traditionally moderate and smooth power curve, which means excellent rear wheel traction throughout the engine. range of speeds. Thus, both two-stroke models have extremely unpretentious engines with enormous net power that the hobbyist can handle, while the professional will be pleased 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 light, 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 ground, which is 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 are 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 fuel injection 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 on the 430 and 480 models (to improve torque and power). All motors now have aluminum bolts to save 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: it is about optimizing the volume, power and inertia of the rotating masses in four-stroke engines. The bikes are lighter and more precise at the expense of slightly less hard power, and above all, they are less fatiguing 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 (i.e. the one that belongs to the class up to 450 cc. ) is the most versatile enduro motor on the market for most enduro riders. It is not without power, but at the same time offers exceptional driving performance. If enduro is your hobby or recreation, you sometimes rely on enduro or cross country racing, this is a great bike that will make you smile from ear to ear under your helmet every time you get on it! Last but not least, we do not neglect a very competitive price.
