Description

Introducing our Heavy Duty Crankshaft, designed to enhance your motorcycle's performance with a +3mm stroke that boosts displacement to an impressive 264cc. This crankshaft is a straightforward bolt-in replacement, allowing you to upgrade your ride with ease. For those looking for even more power, pairing it with the compatible product can elevate your engine to 285cc. Factory assembled and meticulously trued to OEM specifications, this crankshaft is CNC machined and dynamically balanced to accommodate the increased stroke, ensuring optimal performance. It adds between +2.00 mm to +4.00 mm of stroke depending on your specific application, while utilizing the stock piston for convenience. Please note that main bearings are not included, and this crankshaft is not re-buildable due to shorter rods compared to OEM. For maximum performance, it can be matched with Cylinder Works Big Bore cylinders, delivering significant gains in both displacement and horsepower.
