Xenophya were commissioned by Rieju to work alongside Barcelona based Arianetech Engineering in developing the replacement for the RS2.

Aimed at the teenage market, the packaging was... interesting... as it was to incorporate a 50cc 2 stroke, 125cc 4 stroke and 250cc 4 stroke engine. With a ceratain amount of 'compromise' this was achieved and the 50cc model went into production mid-2010 following the concept model launch at EICMA 2009.
