Had my Hyperstrada for a year now. Had my share of problems with it (including noisy brakes and stuck throtle) however in time it grew on me and I find riding it daily very enjoyable. My dealer offered a test ride on the new multi 1200S DVT so i took it for a spin. I strated in the city then headed over to the mountains and back on the highway. Overall the new multi is all a new top brand moto should be. It is comfortable, fast yet torquey, precise and easy to handle. I did miss the "Ducati" feeling of my old vibrating and noisy multi 1100s. In the city the multi is sluggish around traffic compared with the nimble hyperstrada. baggage wise the multi adds nothing in the city. The multi has way superior everything (suspension, brakes, motor compliance, throttle control, computer assistance etc) However, i can not find these upgrades relevant in daily city riding. On the curved mountain road the new multi is almost a sports machine (owing to all the above goodie's) Non the less, the backward sitting position is less fun compared with the strada's. The fun factor is in the middle as the multi can take you VERY fast around the curves with extreme confidence. On the highway the Multi is king compared with the Hyper.The strada feels breathless around 140km/hr. Although it is not really (It is a fast bike), changing cog size improves the feeling. Riding position is less the optimal for long journeys and I found the foot pegs annoying. The multi is comfortable, though I find the GS to be more comfortable. The added cruise control on the multi is the single best example of how car technology should be integrated in motorcycles it works superfluously. This makes long distance travel easier. The next would be to introduce it to the strada the the GPS.
To sum it up
If you live in the city or doing short commutes my take is to stick with the strada.
If you travel long distances (50-100 km/d) or tour a lot I would recommend testing the multi.
