A number of things from the VFR guys, mind you these are Honda pegs and may not fit in the narrower Yamaha footpeg "clevis" as I call it. Grind a mm. off the side and just may.
Most footpeg lowering brackets for FJR's will also go more outboard, so maybe have to extend the brake and shifter pedals because your foot sits more outboard.
Knight Lowering Pegs - direct replacement for stock pegs but top surface is lower, and does not affect cornering ability (same height bottom surface). Contact them for Yammy availability. http://www.knightdesignllc.com/
Buell footpegs are also naturally lower, similar to the Knight idea, perhaps can find ebay ones at a reasonable cost.
A VFR guy made lowering blocks that go straight downward without going outboard, but sorry, VFR unique product... someone should do that for Yamahas.
I was considering Goldwing pegs, as they too are a common mod on some bikes and a little bit lower, trouble is they are wider as well, you'd have to adjust shifter/brake to suit but may not be perfect for your feet.
Yes a higher seat, not sure what Laam does there, but Russell's are definitely higher. You could also try putting your current seat in the higher position. A Russell in the highest position would definitely be the highest.
