PROX offers you this complete connecting rod kit for your YAMAHA YZ/WR 450 F. This complete package will enable you to refurbish your crankshaft, which may have some play from top to bottom. Rather than changing the complete crankshaft, you'll often just need to change the connecting rod. This connecting rod is a cast model sold with its needle cage, anti-friction shims and crankpin. It has the same original dimensions. No adaptation is required. To change a connecting rod, you'll need a press, a balancing bench and a little patience. If you don't have the equipment to do this, you can send us your crankshaft so we can do the fitting ourselves. You can also e-mail us for a quote. All connecting rod dimensions are given below.
