About Harddrive
Harddrive is the house performance and replacement line built for American V-twins, covering everything from engine hardware and electrical to controls, lighting and chassis parts. The range is aimed squarely at Harley-Davidson and Indian riders who want a direct-fit part without dealer pricing, and it spans decades of model years — from Evolution-era Softails to current Milwaukee-Eight baggers.
Enhance your V-twin's stopping power with the Harddrive Stainless Steel Floating Brake Rotor. This 11.5-inch diameter rotor features a 1.99-inch center bore and a clean machined finish, designed to deliver consistent and reliable braking performance. Its floating design is key to better alignment and reduced heat stress compared to fixed rotors.
Why riders pick this
- Stainless steel construction for durability
- Floating design for better alignment and heat management
- Machined finish adds a custom touch
- 11.5-inch diameter, 1.99-inch center bore
A high-performance braking system is critical for rider confidence and safety. This Harddrive floating rotor allows the braking surface to move independently of the hub, which helps in maintaining optimal pad contact and dissipating heat more effectively. This results in a more consistent brake feel and reduced risk of warping under hard use.
Superior Stopping Power
- Durable stainless steel construction for long-lasting performance
- Floating design improves brake pad alignment and reduces heat stress
- Clean machined finish for a custom look
- Counter-bored mounting holes ensure precise fitment
- 11.5-inch diameter with a 1.99-inch center bore
Engineered for Performance and Durability
This floating brake rotor is a significant upgrade for V-twin riders looking for improved braking response and durability. The machined finish not only looks great but also ensures a flat, true braking surface right out of the box. Always verify your bike's current rotor diameter and center bore measurement to ensure a perfect fit before upgrading your braking system.
