I have both an SRX400 (mono-shock) and an MT-03.
If I could only have one, I would choose the SRX400.
However, at present my SRX is still sadly waiting to be fixed again so it's the MT-03 that's the winner!
Don't get me wrong, the MT-03 is great until you buy spares, service the beast and put petrol in it and then it proves more expensive than the SRX. Also, it is rotting away faster than my 21 year old SRX. They definitely don't make them like they used to!!
