On The Pegs
• Die-cast crankcase covers in magne-
sium alloy: ensure very low weight and
optimal surface finish. It also proved
possible to adopt this solution for the
inner clutch cover thanks to isolation of
the water pump from this element.
• Vforce4 reed valve packet: the stop-
pers ensure high reliability without
compromising performance.
• 6-speed dog-box transmission: spe-
cially developed for small Beta engines
with gears made from forged blanks
to provide mechanical strength and
reliability while still keeping size and
weight extremely low.
• Clutch: multi-disc in oil bath with
reverse opening, actuator integrated
into the outer cover. This is a system de-
signed for maximum engine lightness
and compactness. Thanks to low-slung
positioning, it ensures reduction of
power unit size and a significant cen-
tralization of weight, crucial for good
chassis dynamics.
• Exhaust system: to optimize the
2-stroke engine’s torque and power
curves, the Beta R&D Department has
developed a special system dedicated
to this engine size.
• Electric start: perfect start-up conve-
nience whatever the situation. (Back-Up
kick starter option available as an acces-
sory)
• Automatic oil injection: eliminates
the need for a fuel-oil premix.

various solutions were investigated and
developed before reaching a final one
that has allowed a reduction in engine-
generated vibration while maintaining
good engine-frame system stiffness.
• Sachs Suspension: derived from the
rest of the RR range but with its own
settings. At the front there is an open-
cartridge fork of 48 mm diameter.
• Filter box air boot: designed for this
engine type, it improves flow across the
entire rev range, even at low revs.
• Skid Plate: made from tough yet
light polyamide, it features excellent
shielding to stop mud getting between
the engine and the guard itself.
• Fuel tank: compared to larger mod-
els, a slightly smaller tank has been
adopted to improve on-board ergo-
nomics while maintaining good fuel
autonomy.
• Cooling system: specifically de-
signed for this bike, features new hoses
and radiators with specially shaped
reservoirs to fit the small size of the
motorcycle.
• Nissin braking system: extremely
powerful and configurable, the same as
on the rest of the Enduro range. n
