OEM panels (per panel)

Factory injection-moulded ABS, factory paint code

Best forKeeping a low-mileage or resale-sensitive bike original
Trade-offA single upper fairing can cost more than a complete aftermarket kit

Injection-moulded ABS kit, painted

Pressure-injected ABS, painted and clear-coated to a scheme

Best forRebuilding a dropped street bike at sensible money
Trade-offColour match to a factory code is close, not exact

Injection-moulded ABS kit, unpainted

Raw white or black ABS, ready to prep and spray

Best forA custom scheme or a match to faded original paint
Trade-offAdd paint and labour on top — often the larger half of the bill

Race bodywork (fibreglass)

Hand-laid fibreglass, no light or indicator apertures

Best forTrack days and race classes, quick-release fasteners
Trade-offNot street legal as supplied; gelcoat needs prep before paint

Carbon fibre panels

Pre-preg or wet-lay carbon, clear lacquered twill

Best forWeight saving and appearance on selected panels
Trade-offRarely sold as a complete kit; damage is expensive to repair

Compression-moulded copy panels

Lower-pressure moulding, thicker and less consistent

Best forA cheap track hack or a bike being sold on
Trade-offExpect gaps, flexing tabs and drilling to make panels sit

Fitting notes for a dirt like this

  • Plastics are consumables on this class; a full kit is a normal seasonal replacement
  • Graphics are cut per plastics generation — order the kit and graphics together
  • Restore faded plastics with a heat gun before spending on replacements

Before you order

  • Match the generation, not the model name — panels change at every refresh
  • Ask whether mirror, indicator and vent holes are pre-drilled for your year
  • Confirm the kit is injection-moulded, not compression-moulded, if fit matters
  • Check whether the price includes the tail, belly pan and heat shielding
  • Budget for a new fastener, clip and grommet kit at the same time
  • For a race kit, confirm the class rules allow the fastener type supplied

RR 390 4T fairings by model year

Questions riders ask

How much is a full fairing kit for a Beta RR 390 4T?

A complete painted injection-moulded ABS kit typically lands between $380 and $1,100, with $620 the usual figure. Unpainted kits start lower, around $260, and factory panels bought individually can pass that for a single upper fairing.

Will fairings from another year fit my Beta RR 390 4T?

Only within the same generation. Beta RR 390 4T production runs 2015–2026, and mounting points change at each refresh, so always order against your exact model year rather than the model name.

What is included in a Beta RR 390 4T fairing kit?

7-9 pieces plus graphics, covering the main panels plus the smaller trims. Fasteners, clips and grommets are often sold separately — budget for a fresh set, because original clips rarely survive removal.

Are race fairings road legal?

Generally no. Race bodywork deletes the headlight and indicator apertures and uses quick-release fasteners, which is why it is sold for track use.

Is carbon fibre worth it over ABS?

On selected panels it saves weight and looks the part, but it is rarely available as a complete kit and repairs are expensive. For a street rebuild after a drop, painted ABS is the sensible choice.
