2015 Beta 390RS Totalmotorcycle.com Features and Benefits
2015 RS Dual Sport 4 Stroke
The popular RS Dual Sport models are also all new including three different displacements being offered for 2015. RS models share all of the engine updates as the new RR models and are available as a 390, 430, or 500.
RS models continue to lead the “Dirt Bike with a Plate” category offering more off road ability than the competition by offering the same engine, frame, and suspension (including linkage) package as the Off Road RR models. The list of differences between the RR and RS is very short.
2015 500 RS
Class-Leading Voyager GPS units are standard on all RS models and features GPS system, MPH, tachometer, engine coolant temperature, compass, outside temperature, trip meter, maps, as well as a external SD card for uploading and downloading your adventures.
All RS models come standard with the Trail Tech Voyager GPS
RS models are fitted with cooling fan kits for the extreme Dual Sport conditions. The fan keeps engine temps down while going across the Mojave or plowing the silt beds of Baja. Other included features are aggressive Michelin Enduro tires that are designed for 90% off road and 10% on road.
2015 RR 2 Stroke
The 2015 RR Enduro 2-stroke range has also evolved, the 250 version featuring certain technical innovations and the 300 version featuring special parts from the 2014 Racing model.
The objective here is to increase the smoothness and improving power from the bottom to the top end making the “right” power available to the rider at all times and under any condition.
Bike Of The Year is Back!
The 2015 RR 2-stroke engines have undergone some changes aimed at even-better control of engine management, without reducing performance in terms of lightness and power typical of 2-stroke engines with a high output of power.
300 RR 2-Stroke: The engine comes directly from the 2014 RR Race Edition and includes a new cylinder, combustion chamber and CDI.
In particular, the reduced width of the exhaust port and better sealing of the power valve provides improved throttle response and excellent linear power without interfering in any way with the maximum power and torque figures.
The combustion-chamber profile, together with the digital electronic control unit continue to optimize engine output in every stage of operation with primary objective to increase performance and ride-ability of the bike.
250 RR 2 Stroke: The engine’s exhaust valve adjustment system has been modified, increasing the number of adjustment springs from 1 to 2 in parallel, as in the 300cc engine. This change significantly improves engine output, optimizing the opening of the exhaust valve at every stage of operation.
A new silencer for the 250 RR offers a smaller diameter internal pipe compared to the 300 RR which improves the precision of response to the throttle and increases peak revs.
Electric starter motor is under the engine-out of harms way
The Sachs USD 48mm fork has been further developed in close collaboration between Beta and Sach’s engineers and feature numerous important innovations: a new design of the compression piston with “three slot” geometry in order to improve the oil flow and make it more direct so as to absorb violent shocks more progressively. To improve the general smoothness of the fork, particularly on initial impacts, a spring-support release system has been included to eliminate rotational friction, the design of the sleeves and bushings has been modified increasing the distance between the slider and the bushings, also reducing their height. Finally, the spring profile has been redesigned to guarantee better insertion inside the sleeve. Valving has been improved to increasing precision.
A new internal piston with oil passages that have been redesigned to improve its flow and reduce overheating during operation. This means that the shock absorber offers more stable performance, precise and reliable even under very intense use.
Ideal for the most extreme off-road riding and compliant with the standards required by FIM and AMA regulations.
The padding has been redesigned with softer foam
The renewed look streamlines and adds character, maintaining the classical Beta colors.
