Upgrade your Yamaha YZ450F with the Hot Rods 4098 stroker crankshaft, a premium alternative to a costly OEM crankshaft. Designed as a complete, installation-ready assembly, this crankshaft includes proven Hot Rods connecting rods, top-end bearings, and crankshaft webs. It is factory assembled and trued to OEM specifications to deliver reliable performance, durability, and consistent engine operation.
The increased stroke is engineered to provide greater displacement and horsepower while serving as a drop-in replacement in most applications, without requiring engine modification. The Hot Rods 4098 crankshaft is CNC machined and dynamically balanced for the increased stroke and uses the stock piston in most applications. It can also be matched with a Cylinder Works Big Bore cylinder for additional displacement and power gains.
Built for long-term serviceability, this crankshaft is fully rebuildable with genuine Hot Rods connecting rods and bearings. Its gears are manufactured to a quality level of DIN Class 9 or higher, supporting dependable performance under demanding motocross and off-road conditions.
