I know I am not the only RMZ250 rider who experiences speed wobble on the whoops or after the landing of a jump. You're just ridin along then all of a suddenly . I seriously had a speed wobble once while still on the whoops that lasted nearly 50 yds. and felt like forever. I've talked to people who don't ride my bike but said their aftermarket susp. helped alot. I thought about a damper; dont know cost. Any suggestions?
