EVO 2 stroke 250/300cc
Engine
This is the pure-bred of the Evo range, the motorbike designed for experts as well as for the casual clubman rider. As always at Beta, development is never intended purely for power and performance but rather the aim is to always guarantee usability and rideability throughout the riding experience. “This is why we especially aimed to offer rounder and greater torque at low speeds, and thereby increase inertia and centering of the masses – declared Mr. Tozzi, engineer, of the R&D department – which, as we know, are crucial values for improving Trial riding performance”.
To achieve this, the following changes have been implemented, and are common to both 300 and 250cc:
– The engine crankshaft now more rigid thereby increasing inertia and centering of the masses to provide yet more balance.
– New connecting rod and crank pin for improved inertia and rigidity.
– New silencer, internally redesigned for considerably greater torque at low to medium speeds as well as a more silent operation.
Changes to 300cc
– New combustion chamber, re-developed squish angle to improve response precision and engine output.
Changes to 250cc
– Completely redeveloped head thanks to a new design of the intake and exhaust ports for standard usability, making the bike one of the easiest to ride on the market.
– The combustion chamber is also new, with reduced squish height and geometry dedicated to the new ports and port timing.
EVO 2 stroke 200cc
Engine
Now based from the 250/300 engine, we can say that perhaps this is the model size that is no longer the step-brother of the larger EVO models. Prior EVO 200 models were based from a version of the 125cc, however for 2016 the engine now has its own personality thanks to numerous technical implementations, making it an interesting engine size for the evolved enthusiast.
– New crankcase derived directly from the 250/300cc engine (and no longer from the 125cc one, as in the past).
– New engine crankshaft with lighter dedicated flywheel. This has allowed a more correct distribution of the weights, with centered masses and improved inertia. The most striking result is considerable improvement in motorcycle handling.
– Even the connecting rod is new. Thanks to improved rigidity, vibrations are greatly reduced and riding is more enjoyable.
– New lighter piston
– Increased crankcase compression ratio.
EVO 2 stroke 125cc
Engine
This has always been the rookie engine size for young Beta riders – the one which allowed Marco Fioletti to win the World 2015 title – and this year it continues to grow in terms of performance. Notoriously lively and brilliant, today the 125 provides an improved feeling of power that is fun for both the younger generation as well as the more mature riders. All of this thanks to:
– Re-developed engine crankshaft for improved inertia.
– New connecting rod, shorter to increase compression in the crankcase and therefore achieve greater performance at low end.
– The porting of the cylinder has been redeveloped to match and exploit the improved torque
Frame
Changes common to all engine sizes in the EVO 2 strokes (300, 250, 200 and 125cc) and EVO 4T (250 and 300cc) range
The Sachs single shock now features new valve settings to improve the rebound feel which has allowed the shock to work better in junction with the front fork. As the sport has evolved, this improvement is directly aimed at improving the feel while the bike is being ridden on the rear wheel.
Colors:
The new colors are trendy, making the white painted aluminum frame really pop, combined with the mix of white, black and fluorescent red plastic parts and graphics.
With the demise of a couple Spanish brands, Beta found it necessary to offer the popular Evo SS (Super Smooth) model in both a 250 and 300 2 stroke. These SS models will appeal to riders looking for a bike that provides a softer power delivery and less “power pulses”.
EVO SS MODEL:
The SS (Super Smooth) is in its fourth season and was built for the trial rider that wants a bike that can be ridden slower in the sections. New for 2016 is the availability of the 250 SS alongside the 300! Beta USA starts with a standard Evo model and adds the following items:
– Special Titanium exhaust header pipe to reduce the engine’s power pulses
– Heavy flywheel assembly
– Smaller front sprocket to work in junction with the exhaust pipe and flywheel
– Larger diameter Domino grips
– Slow action throttle assembly with a special throttle wheel to improve the power delivery
– Special “Super Smooth” decals
– Available in 250 & 300 cc 2 stroke.
Also returning is the popular “Mad Max” looking Evo Sport! It is a great bridge between a standard Evo and a Xtrainer. Designed for slow speed trail riding, the Sport models are available in 125, 200, 250, and 300 2 stroke as well as 250 and 300 4 stroke sizes.
EVO SPORT MODELS:
These models are designed for slow-speed trail rides and extreme play riding. Beta USA starts with a standard Evo model and adds the following items:
– Long range fuel tank/seat combo
– Hand guards
– Larger front sprocket for casual trail riding
– Knobby tires w/ front fender lift kit
– Digital meter mounted on handlebars
– Special “sport” decals
– Available in 125, 200, 250, 300 cc 2 stroke and 250 & 300 4 stroke
