Ive owned 1 of these 2 Aprilia Rs125s and 1 Rs250.
The mito doesnt compare to the aprilia at all, ive riden all 3 at eastern creek and eventhough the 125 may seem like a fun idea its not.. Aprilia is a whole lot better bike if you want the whole 2 stroke thing and what not. But for a learner legal id go a ducati 620 monster or even a 600 even thought the rule is 150kw per tonne for a bike - there is a mob down near the city that have pushed for 600cc bikes to be restricted and have them passed as learner legal and yes thats the R6, Gsxr600 etc
