The superdual will not be upgraded to Euro 5. It is no longer produced and the latest Euro 4 are being sold.
It is hoped that in a short time a valid alternative will be proposed by SWM I hope more similar to the RS650R and TE630
I agree there, would be great if they had serious shot at an updated 630, that is, something you can ride more like a dirt bike. Having ridden an E4 SuperDual X offroad, I can say they're definitely not as well suited to that as I hoped, particularly with the seat and tank shape. The low ground clearance and shorter suspension travel isn't sufficient for spirited offroad riding, but would be okay for just putting along and exploring a little.
As much as I like the Husky 701 LR, it's seriously expensive over here in Aus, so a bit of a rival could only be a good thing!
