It's still a rather small windshield. Takes wind off your chest but your shoulders and helmet still gets the brunt of it.

However, that said. If you tuck down, you can just get the helmet under the wind blast for a top speed run. It's a naked bike afterall. You will get lots of wind. But cruising at 130 to 150 isn't too bad for a few hours ride. The stock aero isn't too bad to begin with.

There is a bigger handlebar mounted windshield available for our NK but I don't like how it's mounted. Looks like an afterthought. Mine looks like OE that came with the bike

Will be reaching the 30k schedule major maintenance with VC check in 3-4 months. Will know for sure if the cheese cam problem affects our bikes or not. So far no reports of cam failure on the 800nk and 800mt yet...so hopefully that issue has been addressed.

nice update

The issue is probably not the camshaft but something more serious. There are reports that the oiling journals for the cam oil squirters have been improperly machined leading to inadequate oiling of the cam lobes.

KTM already released a statement that the cam shore hardness is not he issue.

If this was the issue, it would be a full head replacement.

I saw 1 video, it says oil starvation - oil galley size, oil path machine hole mismatch, and oil screen

I think maybe a few factors combined... oil feed, oil starve, and VC gap

the photos online show premature wear started and looked like those piston seizure score marks due to heat and oil film breakdown etc...

some sources show the fuel map runs lean at 15:1 AFR below 5k RPM, not sure if this can affect exhaust valve temperature or not

I hope it is not the case for the NK's
