Got pivot riser on my M8 with 04 sno pro bars( appear same as F7) about like a 4" riser on standard bars, forward about 2" from stock M, but most importantly you can rotate the bars so the bar ends are level or slightly down, level or slightly up on a dirt bike is guaranteed arm pump and last place, I have always found the same true on sleds. Rode my M5 about 200 miles this last week, still has the stock M series Mtn bars wioth 3.5 Ole's riser, what a huge step backwards, head and shoulders above the way ignorant stock position but not as good as sno pro setup.
Should be able to stand on our sled, close your eyes, arms in natural riding position and lower then onto your bars and not find any wrist cramping long horn steer goofy hand and arm position. Stock M bars must have been designed for visual affect only.
