Expensive ornament ! Will it get used especially having 2 similar bikes and the one in front will always be the Ktm and certainly more rewarding to ride.
The KTM is faster, but in the short test ride I had, there were some minor niggles. The brakes aren't as good as my GSA, and there are a lot more vibes through the frame. The heated seat on setting 0 was quite effective! But, the torque was immense. My XR is faster, but it's all at the top end, which is pretty pointless in the real world, unless you want to live in fear of losing your license.
I'm looking forward to spending some quality time on the 1290 to see how good it really is, once I get used to it, and get some miles on.
As to the GS sitting there as an ornament, that won't happen. Getting back on the GSA afterwards, and spending the rest of the day on it, on all types of road makes you realise how good it is as an all rounder. It'll be a tough act to follow.
