Want more top speed without giving up spool response? These ProBld lightweight final drive gears are 20% lighter than standard gear-up kits — meaning quicker revs with a higher final drive ratio 🏁⚙️
- 🪶 20% lighter rotating mass for faster engine response
- 🚀 Higher top speed capability
- 🎯 Best for builds with strong low-end torque
The Details ⚙️
These gears are designed for riders who want the benefits of a gear-up kit but don’t want to lose throttle response or acceleration. By reducing rotating mass by roughly 20%, the engine can spool up faster — helping balance the typical downside of tall gearing. That means acceleration stays lively while still gaining more top-end speed.
If you're running a built engine or already feel like you have solid low-end torque, these gears are a great match. If you're still stock or mild, you may want to consider a big bore kit, CVT tuning, or variator upgrade to help support the taller gearing.
Installation requires basic tools and a press. If you don’t have a press, we can ship them already installed on a new countershaft for a simple bolt-in experience.
