Hot Rods 4-Cycle Stroker Crankshaft

Unleash significant power gains and increased displacement in your motorcycle engine with the Hot Rods 4-Cycle Stroker Crankshaft. This expertly engineered crankshaft assembly is designed to provide a direct performance upgrade, delivering enhanced torque and horsepower for serious riders.

Description

The Hot Rods 4-Cycle Stroker Crankshaft is meticulously factory assembled and trued to meet or exceed OEM specifications, ensuring exceptional quality and reliability right out of the box. Engineered for a seamless installation, this performance crankshaft often serves as a drop-in replacement, requiring no modifications in most applications. Each unit is precision CNC machined and dynamically balanced to perfectly accommodate the increased stroke, ranging from +2.00 mm to +4.00 mm depending on your specific motorcycle model. This extended stroke directly translates to a larger engine displacement, contributing to substantial horsepower and torque improvements. Constructed from robust 4140 Steel, this crankshaft assembly is built for durability and high-stress environments. It offers excellent compatibility with Cylinder Works Big Bore cylinders, allowing for even more dramatic displacement and horsepower gains, potentially reaching up to 379 cc in optimized setups. While designed for performance, it typically utilizes your stock piston, simplifying the upgrade process.
