I've ridden them both back-to-back on rural roads, about 90 min each, two-up. And on another occasion in the city, plus have also ridden each solo briefly. They felt less similar than they appear on paper. Overall my take was that the KTM would be the go for solo riding where gravel roads were a big part of the mix, while the Multi was better for two and for long-distance blacktop use. The KTM felt beautifully specced, with the instruments a particular standout. Different coloured warning and indicator lights popping up like jewels on the panel when needed but disappearing when not. Very light clutch, lovely gearchange. Bike feels very narrow at the rear, widening at the front to take on the fuel load. Nice riding possie but the seat is a bit narrow - obviously built to work well when you're standing. I imagined I could feel the springiness in that chrome-moly frame. The suspension I rated as good but not great - might have changed my mind with more use. The motor was beautifully responsive off the bottom and plenty powerful but didn't develop into the loping mid-range mile-eater I'd been hoping for. Felt like a bit more flywheel mass might have helped. Perhaps something else that would grow with familiarity. The Ducati motor felt much less refined off the bottom, and that flat monochrome instrument panel - lauded when the bike was released - looked crowded and dull. Heavier clutch and notchy gearchange (I suspect that is mainly in the positioning of the lever and linkage). Chassis felt a bit dead and, for a Duc, so did the motor - I'm thinking the steel-aluminium sandwich frame soaks up a lot of the engine feel compared with a full tube-trellis model. I'm talking feel here - obviously there is plenty of power. The Ducati seats the rider closer to the steering head, which feels a bit restrictive at first but means the pillion is further forward also for more balanced handling two-up. You can feel the steeper steering head angle compared with the KTM, and also the wider rear tyre - better grip on the smooth stuff, but a bit more affected by bumps hit off-centre. The Skyhook suspension is probably better than the WP electric stuff on the KTM we rode. Seats for both rider and pillion felt much broader and more supportive for long-distance work (but too broad for comfortably moving around on the bike while standing off-road). I didn't like either screen much at speed and in truth, my conclusion from the test rides was that I didn't like either bike enough to sell my S4Rs for one. Which was surprising since I've wanted a two-up bike and have been looking lustfully at both since I heard they were coming. Might have just had a bad day, and we were a bit rushed. I will try both again. As I've posted elsewhere, I'd be more interested in the KTM if the local importer was bringing in the model with the manual rear shock. The electric version is a single-chamber design with only four preload settings and three damping presets for each. I think they have set it up beautifully given those limitations. For solo work with occasional pillion use, great. For pillion work with occasional solo use, not so much and you're stuck with it. [FWIW I also rode the new GS. Best part of it was the airflow management, which I thought completely acceptable and much better than the KTM or the Duc. Nice riding position, comparable suspension - well, the BM's active damping could be set softer than the Duc's, but I don't know that I'd ever want it that bouncy. For cruising, again I thought the motor needed more flywheel, but it was saved by the electronic cruise. Big disappointment for me was that the motor felt very busy at highway speeds. Again something you'd probably acclimatise to but top gear felt like third. Of course, two-up and loaded with a head-wind and uphill, I might welcome that gearing.] The impression I'm left with is that the KTM was the only one I'd want if the typical ride brief included sporting use over a fair bit of gravel or worse. That springy steel-tube frame, narrower tyres and more spartan seating would make it fun to ride fairly hard on loose and rough surfaces. It would also be great on winding two-lane blacktop. The other two felt like they would cover the same ground, but I'd be less interested in riding them hard there, as opposed to plodding along looking at the scenery. But they'd be more comfy on long, dull bits of motorway and better for two, with the Multi the sharper road tool for high speed stuff.
