With a little patience you can usually find sweet deals in the for FOR SALE section. I picked up +2+1 arms, top quality shocks, YFZ brakes, and some other odds and ends for half the price of new. The suspension allows me to control the 421's power. I wouldn't want to ride a banshee with that motor on stock suspension components. While the suspension won't make you much faster in a drag race, it WILL make you faster than any bolt on motor mod on any hair scramble, MX riding, black diamond trails, ect.....
