I rode a Pro Circuit modified KTM 450 SX last night. Suspension was unbelievably plush. I liked the KTM clutch feel too. Now I want my yzf the same. Has anyone had Pro-Action modify their '03 450's suspension for motocross? How is it for plushness and soaking up big hits? Also, anybody have a Magura clutch on their bikes? Did it make pull much easier?
