I have the previous S and it is brilliant, tested the R model (2019) but don't like the feel of the front as much, although IMHO the suspension is of greater quality on the R models.
Tested latest model and think it is a bit better in most areas, except leg room, but when upgrade time comes I would still look at the KTM over the competition.
Have to admit the current R colours are fantastic, and not surprising they are selling so well, but would still buy an S as really it is the bike for me.
Discounts for KTM's have been a bit thin last few years, and all manufacturers do it, I was once offered a GS that was not discounted - but had a £1750 "deosit contribution" and £1200 of free extras, but definately not a £3,000 discount of course as that would devalue other existing customers bikes....
...Obviously their 6 month old standard bike would still sell secondhand for the same price as a new one with panniers ;-)
I have been lucky and got a good discount in 2016 and in 2019, but other years nothing I fancied came up cheap, and some models you never see discounted, just depends what has got to the "sell-by" date and needs clearing out each winter, and as long as you are not trying to flog your used bike whilst the same is on then no problem - just wait until spring when the leftovers have gone and new models appear at full RRP ;-)
