HOT RODS STROKER CRANKSHAFT YAMAHA YFM700R 06-09 4178

The Hot Rods line of drop-in stroker crankshafts show true innovation. Not only do these stroker cranks bring about a heightened level of performance, but do so without costly case machining, custom cam chains and spacer plates. Better yet, many Hot Rods stroker cranks even utilize the engine’s stock piston.
