Just demoed an RX and SX back-to-back. The SX wins hands-down. Even for occasional track riding, I'd take the SX without hesitation. There's something more to the SX that can't be explained by ergos alone- it has a completely different nature from the RX. My post-demo preference rating is as follows: #1 SX, #2 X1 I rode there on, #3 RX. I honestly don't think I'd buy an RX for the street- it's a thoroughbred race animal that was borderline disappointing on public roads. The SX does everything the RX does, only better. I was totally surprised by this experience- the SX is just that different. Go ride one and see for yourself.
Same thing I noted on the 1125s. The R was fun on the track, and extremely capable...but I bought a CR. Granted, there's a gearing difference between the R/CR, but I just like the CR better. More....soul. Like a new S1W
I'm not allowing myself to ride ANY 1190 at all until the AX arrives. It's hard enough to wait, without a test ride...
The SX is the exact same bike except for handlebars .. same engine, same gearing, etc not sure how there could be something "more" unless its all in your head.. ... When I was a single bike owner I chose a 1125CR after riding both the R and CR because it was more comfortable. Now that I have a my HD Sportster to cruise, my Monster to ride Hooligan and my R to feel like a racer ... I have all bases covered
I think the SX will be the hands down winner for EBR in the sales race between the SX and the RX. The RX is a dedicated track bike with great street manners! The SX is a dedicated street bike with great track manners. The reality is most of the people in the ERB target demographics are looking for the SX and AX as their racer boy days are behind them. The SX and RX are the same machine but the seating and bars on the SX make it more accessible ,comfortable, and practical for the less committed(non track day street only) riding set.
Interesting info on where the pieces originate from the Cycle World article:
Many of the chassis components come from overseas: the Showa suspension and Nissin brake calipers from Japan; the GSK front brake rotor and ZNL wheels from China, etc. But many are made in the US, including the twin-spar aluminum frame (which doubles as the fuel tank) made in Illinois; the rear brake caliper, made by Hayes in Wisconsin; the radiators, made by Thermal Dynamics in Southern California; and the bodywork, made by Hotbodies, also in California.
