For a comparatively small Italian motorcycle manufacturer, Beta has been making leaps and bounds in the enduro dirt bike world. Winning and leading a number of international events and classes. For 2015, Beta has completely revamped their four-stroke line up with new displacements and major changes throughout, while the two-stokes received refinements and trickle down improvements from Beta’s Racing Edition models.
“ Our team are very excited about the new 2015 model line up with all the new changes, we already had an excellent and competitive model range with the 2014 models, with the changes and improvements on the new 2015 models they have to be dynamite” said Craig Langton DP for Beta SA and the Cayenne Group. “Some of the models are with us at the moment and others are in the pipe line, we will make an announcement of their availability, arrivals and pricing later”.
Beta engineers were clearly hard at work in preparation for the 2015 model year, with changes announced for its bikes across the board. Substantial updates to the RR 4-Stroke engine (available in four capacities 350 cc, 390 cc, 430 cc and 480 cc) highlighting the coming year’s upgrades. In addition to the inclusion of a Beta/Synerject developed electronic fuel injection system for the new 350 RR.
The inclusion of EFI (Electronic Fuel Injection) on the 350 RR marks the first production Beta to be made available with Fuel Injection and the system comes with a 42 mm throttle body and stepper motor to ensure engine performance remains consistent in a wide variety of conditions.
2015 Beta RR
During the past few years Beta has focused primarily on chassis improvements but for 2015 the Italians are focusing on the powertrain, resulting in lighter engines for all motorcycles in the RR and RS range.
RR Four-Strokes: 350 EFI / 390 / 430 / 480
- All new displacements for optimum performance and handling
- New crankshaft, connecting rod, cylinder head, and piston
- Electronic Fuel Injection (350 only)
- Engine from the 2014 Factory Edition (350 only)
- Die-Cast Engine cases (up to 1.5 kg’s lighter)
- New front fork compression piston to improve oil flow and reduce harshness
- New rear shock piston to reduce heat
- Handlebar pad from Race Edition
- New design seat foam that is softer
- New graphics and colour scheme
Big News Is The Beta 350 EFI…
As the name says, the big news for the 350 cc thumper is EFI, the only model in Beta’s line up to have such. But the even bigger news is that the RR four-stroke enduro model line-up features three entirely new displacements. While the 350 stays the same size, each of the other models have downsized a bit, a switch that Beta claims creates “the perfect displacements.” Even though the new engine sizes are smaller in cc’s, Beta says that, with their completely new engine layout, the bikes “provide the same horsepower and torque as the 2014 models yet with more ‘usable’ power for the rider.”
Instead of minor changes, Beta renewed the entire engine for the 2015 four-strokes. Too many details to list, some of the main changes are a completely redesigned main cases which are now die-cast saving as much as 1.5 kg’s , new oil pump drive system, redesigned crank case chamber, lighter clutch and flywheel covers, lighter crankshaft shoulders, lower-positioned combustion unit for better mass centralization, a new piston, cylinder and redesigned head. All of the changes were to make the motor more compact, lighter, and more efficient.
The chassis’ also have some upgrades and these improvements are applied to all 2015 Beta models. The suspension received some changes by way of a new compression piston with “three slot” geometry in the Sachs fork, designed to improve oil flow and make it more direct so as to absorb violent impacts more progressively. The Sachs shock has a new piston to reduce heat to provide more stable performance over long rides. New graphics also grace every model and last, but definitely not least, the seat gets a much-needed softer foam.
RR Two-Strokes: 250 / 300
Beta didn’t leave out the new 2015 2 strokes they also got a new face lift across the board and now have the competition-honed power plants from the Race Edition models. The motor features an updated power valve, new CDI mapping, new cylinder, and new combustion chamber. The stock FMF exhausts are also new and shaped differently for the 250 and 300 cc machines. All of the chassis and suspension changes above apply to both the 250 and 300 models. Other new mods are rear shocks, race handle bar pad, new softer seat and new graphics
- Engine from the 2014 Race Edition
- Updated power valve for more linear power delivery under all conditions
- New CDI mapping to match new engine
- New front fork compression piston to improve oil flow and reduce harshness
- New rear shock piston to reduce heat
- Handlebar pad from Race Edition
- New design seat foam that is softer
- New graphics and colour scheme
