A: To give a more accurate recommendation I would need a little more information. Riding Type (MX, SX, Desert, Woods, Trail/Enduro, Etc.), Skill Level/Racing Class (Beginner/D, Novice/C, Intermediate/B, Expert/Pro/A), Gas Tank Size (stock or oversized) as well as Age, Height and Weight all factor into proper suspension set up.
