MY21 - RR 390 4T RACING

Suspension
– Kayaba AOS forks with closed ø 48 mm cartridge: these new KYB spring forks feature a closed cartridge design and are renowned worldwide for being top-of-the-range. Close collaboration between Beta and Kayaba has created a bespoke product which features a new fork shoe design and a unique calibration reserved for the RR models. Also, the presence of anodized internal components minimizes sliding friction, whilst the customary compression and release adjusters allow easy attainment of optimum settings at all times. Therefore, Kayaba forks ensure excellent operation under all usage conditions, being ultra-reliable, and easy to tune.
– ZF ø 46 mm shock absorber with new calibration: this newly refined set-up lets riders make the absolute most of the new chassis.
– Black anodized triple clamp.

Premix
In response to riders who are always looking for lighter motorbikes, Beta R&D department has once again decided to dispense with the automatic mixer in order to reduce the bike weight as much as possible. The 2-stroke RR Racing MY 2021 machines run on oil/gas premix, thus honing the racing pedigree of this version.
The oil mix can be installed as an after-market accessory (art. 040.46.002.82.00), at a reasonable
price and labor time.

Special components
