Right this is the only thing i could find but its reviewing the 2007 Beta Arc 50 - One.
as far as i can tell its a scooter spliced with off road DNA.
right heres the short write up they gave it:
what can come out from the fusion between a scooter, born with an Off-Road DNA, and a raging Enduro 4-stroke¿ You can get the answer just mounting on the brand new Beta Ark RR Racing. The aggressive red flou coloring, and the racing graphics inspired by the RR Enduro 4t riding the World Enduro Championship, give the right energy dose to a sporty and aggressive scooter. Robust frame, brilliant engine, powerful double disc braking system, hydraulic fork, adjustable monoshock and… all the guts courtesy of a ready to race enduro bike: that’s Ark RR Racing successful key!
