Beta RR 50 Enduro - version with aluminum frame
A specific version of the Beta RR 50 Enduro was produced between 2004 and 2008, featuring a perimeter frame made of aluminum, its own design, and body parts that clearly distinguish it from the Racing model. A high-quality chassis designed for demanding off-road use. The upside-down fork, aluminum swingarm, disc brakes, and large enduro tires create a package that stands out in the 50cc class.

Spare parts and tuning parts for Beta RR 50 aluminium
Maintenance of this rare version of the Beta RR 50 requires suitable and high-quality spare parts.
