The LSR DC4 A-Arms (Yamaha Candy Red), Fox X Evols, Fox Podium Rear, Brake Lines & clamps, and LSR Axle are amazing products! The red A-Arms matched the 2010 Yamaha Raptor 250 perfectly and look awesome! The Fox Shox work great; the ride is smooth and predictable. These additions made the Raptor handle better than most race-ready 450s! Very happy with all these products. They made the bike a lot more fun to ride!
