Interesting to read the opinions of others on this topic.
I found that bar risers (Ballards $30) on my 99 Kato 300 made a world of difference to my standing position and jumping confidence - based on stock AFAM bars IIRC.
Note: I am 194cm or 6ft in the old units.
I also found that too much higher was going to upset my comfort when sitting and cornering, yet I would like another inch when standing.
The solution was to drop the pegs 20mm. This gives me a general lower C of G standing, plus the added comfort and balance in standing ergos without making me feel like I could not get my weight forward enough and elbows high enough to corner when sitting.
The added bonus of bringing my knees in line with the sides of the very slim KTM300 seat when standing makes it better to control the bike when riding standing through greasy track conditions and provides better grip when accelerating in the standing position also.
A taller seat foam to compliment the ergonomics is on the cards also.
Most bikes are designed around a 5' 8" rider around 75 Kg - so most of us will need to tweak a few aspects to get the most from the bike and be at one with the machine.
7075 T6 Material used on high end bars is very strong and very susceptable to Stress Corrosion Cracking (SCC). The anodised finish is very good protection, if it is scratched or abraded the corrosion will set in very quickly in the right conditions. High cyclic loading and corrosion are all that is required for SCC to take root - It is the silent killer in the aviation world.
