Build quality and reliability on the scorpa is easily as good as a mont, and an sy 250 feels much more modern + lighter to ride than a 315r..
and is bombproof, i've had shercos,monts, gassers, betas, fantics and scorpas so i've tried them all.
I've had 4 sy 250's and never had any trouble with any of them!!
and i've had 3 315r's! no trouble with the monts either.
The mont 315r is a good bike but it does feel a little bit dated to ride "10 year old technology"
try a get a ride from somebody??
I'd go for the SY!
