i have Moose risers and kx high bend bars. i'm 6'6' and wish i could actually scrape up another inch of rise, its comfortable now but higher would feel better in my lower back. I should try offset pegs for stretch in both directions. My bike had a 8mm rise 7/8 into 1 1/8 aftermarket bar clamps (probably moose too) when i bought it from another tall guy, but i got the 50mm risers, the tallest available to help out. they come in 8, 30 , and 50 mm. They mount into your stock 7/8 lower clamp and allow for 1 1/8 after mkt bars, like all the high bends available. They have survived crashes that bars have not, but my only complaint was that i had to modifiy/ cut the supplied bolts to make it work. Oh, and worth mentioning... you can still run your stock length fr. brake, clutch, and throttle lines with some minor re- routement. Moose racing products are available thru Parts Unlimited.
