Carbon Fiber Star Tek Rear Wheel by BST Aprilia / Tuono V4 1100 / 2021

BST (Black Stone Tek) carbon fiber wheels are the lightest and strongest carbon wheels available, making them the ULTIMATE upgrade for your motorcycle. Weighing between 40 and 60 percent less than some OEM wheels, BST "Star Tek" carbon fiber wheels offer sharper handling, faster acceleration, and quicker braking for your motorcycle. Lighter wheels are also easier for suspension systems to control over bumps and irregular surfaces, yielding more traction and unimpeded acceleration. Less rotating mass also equals less rider fatigue.

Using high-tech processes pioneered in the aerospace industry, BST carbon fiber wheels are manufactured in a single molding operation. This technique produces a wheel that is far superior in strength and much lighter than any aluminum or magnesium wheel, and one that is light and strong enough for racing and street use.

BST wheels are a unique monococque (single unit) design with hollow spokes. The end result is wheels with unsprung weight reduced 40-60 percent compared to stock wheels. This delivers the lowest possible moment of inertia, a critical factor that affects all aspects of motorcycle performance.
