How does sweep affect arm pump?
I ve got the twinwall 994 ktm high with just 40mm sweep now.. been struggln with some armpump lately. Figure I should try a handlebar with more sweep maybe. Maybe 54 or 65 sweep. I remember reading an article about this a few years ago and according to it you should gain strenght and lessen the risk for armpump with more sweep.
Anyone got any experience testing different sweeps?
And have you got any ideeas on how wide bars you suppost to have? Are u guys shoppn your bars ends of or do you ride them full width?

Been looking for a pair of used PHDS mounts, maybe going to try that if I still get armpump/sore with the new bars.
The bars that I loved on my '16 YZF450 were swapped to my '17 SXF450 and my arm pump increased dramatically. After rotating them multiple ways with no relief, I went back to the stock Nekens and arm pump went back to "normal".
Try set the bars in line with the forklegs so you can draw a straight line from center of foels, through the bars.
If you still get armpump, role them back 1mm at a time
I used to run the twinwall 997 which is probably the most popular bend and it has a lot of sweep. I'm 1m87cm and always felt cramped with those bars. Now I run bars that came stock on 2016 KTMs, which have something like 10-12mm less sweep than the 997s and feel a lot better.
To sum up, I don't think sweep directly relates to having more/less armpump but I do think the length of your arms relates to the amount of sweep that feels comfortable to you. Most motorcycles seats/handlebars/footpegs are built for people that are around 175cm, so if you're not around that height, I would evaluate the controls on your bike to see what's possibly causing the problems.
Pit Row
You don’t want much sweep, the more sweep, the more your elbows are tucked into your sides.
Fitting almost perfectly in the middle of the Renthal range of bends, The RC Bar bend is one of the most popular amongst all bends.
Popularised by Ricky Carmichael during his time at Pro Circuit Kawasaki and American Honda. This bar has been adopted by many top level riders since, including MX2 World Champion Jeffrey Herlings.

I think this is the same as the Windham ProTaper ???
No arm pump. At all.
