PROX offers you this complete connecting rod kit for your KTM 250 SX/EXC and KTM 300 EXC. This complete package will enable you to refurbish your crankshaft, which may have some play from top to bottom. Rather than replacing the entire crankshaft, you'll often just need to change the connecting rod. This connecting rod is a cast model sold complete with 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.
