KKU63006-103-XL Hi-torque Starter Motors

For riders dealing with hard-starting Big Twins, the Spyke Hi-Torque starter motor offers a significant upgrade in cranking power. These starters use intelligent gear reduction to deliver substantially more torque than the original equipment—up to 46% more for 1989 and later models—without requiring a larger battery. Spyke developed these units to handle high-compression engines with ease, ensuring your bike fires up like a stocker every time. Finished with polished aluminum components and chrome steel hardware, this starter fits Big Twin, FXR, and Touring models, combining show-quality looks with heavy-duty performance.
