The stock bar height on my 07 WR450 is way too low for me (6'3") when standing. I raised them up with 1 barclamp spacer and it's still too low. I'm considering 1 more which makes them 1 3/4" taller than stock. Question is how does this affect steering geometery, and do you think a stack of 2 additional spacers (under the bar) is strong enough for normal off-road (no track) riding? I know I could go with a higher bar - that's option #2. Thanks.
