I have an extra 1-1/18" bar from an 03 KTM that would work great on my 03 KX 250 with the ~3/4" risers they sell for stock clamps. I noticed that some companies say their risers are for solid clamps only. The KX bars are rubber mntd. can I still use these ? it seems like it would be the same thing as buying a taller bar. Does the taller height at the clamp change the leverage ratio or something ? I want to keep my clamps rubber mntd. and need the added rise as the bars are too low for me otherwise. It may be cheaper just to buy taller 7/8 bars but I'm just checking my options since I already have the extra 1-1/8" bars
