RR 50 RACING MY20

RR 50 RACING

For any youngster eager to ride a real motorcycle, the Beta RR 50 has always been a dream bike.
This is a ’50 cc runabout’ in terms of engine displacement only. Everything else is top-of-the-range: assertive styling, features normally seen on bigger-engined bikes, top-class finish, a perfect mix of maneuverability and stability plus superb riding ‘feel’.

RR Enduro 50 Racing
This top-of-the-range bike is – in terms of both technical features and aesthetics – a direct derivative of its bigger cousins that compete in the Enduro World Championship.

The features that put it right at the top of its category are:

  • Precision-cast footpegs
  • Aluminum swingarm
  • Adjustable upside-down 41 mm fork
  • Tapered 28.5 mm brace-less handlebar
  • Expansion chamber exhaust with nickel-plated finish
  • Red-anodized aluminum silencer
  • Rear suspension with progressive linkage
  • Adjustable rear shock (preload, compression and rebound)
  • Dual radiators
  • Unified single-key security system (for ignition, steering lock and fuel cap)
  • Passenger grab rails incorporated in the rear plastic body
  • Aluminum alloy wheels
  • No fuel-oil mixer (making the bike even lighter)
