The savings may vary depending on your make and model. This chart is for an R6. So if you’ve ever wondered just how much weight is saved by swapping things out or deleting them completely, here’s a guide.
The largest gain in performance however comes from the loss of rotating mass and the inertia that comes with it. The dropping of rotating mass is measured with a scale, but the gains are substantially more than what a scale can show. Along with that reducing unsprung weight is the next biggest gainer when it comes to influencing performans. Less unsprung weight helps the suspension work the way its intended.
Here is an excerpt from the OPPRACING website.
Blackstone Tek (BST) is the world’s premium manufacturer of carbon fiber motorcycle wheels. BST Carbon fiber wheels are the lightest and strongest wheels available. Installing BST wheels on your motorcycle is the single most effective modification you can perform.
What’s so great about BST Carbon Fiber Rims?
- Faster acceleration
- Faster braking
- Easier cornering and manueverability
- Ultra-high tolerance to damage
- Low corrosion susceptibility
- A very cool 3D appearance
The lightest, strongest motorcycle wheels available
How light is a BST carbon fiber rim? A Suzuki GSXR 1000 2005-2006 front wheel is 5.8 lbs, the rear wheel is 8.8 lbs and the sprocket carrier is 2.0 lbs! To contrast, a set of forged aluminum rims can be over 24.0 lbs, nearly 8.0 lbs more!

|MoI = Moment of Inertia. Think of it as “BST is X% better than the other wheels!|
|Independent testing performed by Sport Rider Magazine (February 2004 edition) based on 2004 Suzuki GSXR1000|
|Without getting too technical, Moment of Inertia (MOI) is the relative difference between how easy or hard it is to set a wheel in motion around an axis of rotation. The less energy it takes to spin the wheel, the faster you can go! For a detailed explanation of MoI, start with our friends at Wikipedia!|
|How does this affect your performance?The energy needed to turn these wheels obviously comes from the engine. If you needless energy or power to turn your wheels, the available power accelerates the wheel quicker and you will end up with a higher maximum speed. But how much power can be saved by using Carbon wheels?

|Are BST Carbon Fiber wheels safe to use?
Despite the many internet myths, BST carbon fiber wheels are completely safe for the street or the track. Carbon fiber is an extremely robust material – even if you somehow succeed in damaging the wheel, the damage will not propogate while riding. To demonstrate the strength of a BST carbon fiber wheel, Race Applications Monaco (RAM) applied a 10,000 Newton stress test – that’s enough energy to move 22,000 lbs about 3 ft. in a second.
