The look and performance of BST Carbon Fiber wheels
BST wheels are hand crafted from ISO certified materials. BST's wheels are extensively tested and there is no doubt as to their structural integrity. BST takes pride in producing wheels that are as aesthetically perfect as possible. Occasionally a wheel may exhibit slight irregularities such as slight weave distortion, light or dark marks from resin flow or natural porosity resulting in small 'fish eyes'. These irregularities are acceptable by the motor industry and BST and do not affect the structural integrity or performance in any way whatsoever. Should your wheel exhibit such irregularities, please consider it the signature of uniqueness - a product crafted by hand for your enjoyment.
BST wheels are made specifically for a type and model of bike. Part of the manufacturing process ensures that the wheel runs absolutely true on its own hub. The hubs have a unique fastening system.
The BST warranty covers all workmanship for a period of 2 years from date of sale to the rider. This is regardless of the date on the wheels - the date on the silver sticker indicates the date of manufacture of the carbon part. There is no shelf life for carbon fiber.
BST Street wheels are designed for normal street and track use. BST RACE wheels have a different and lighter carbon layup, as well as 7075 T6 aluminium hubs. These wheels are even lighter than the standard wheels and are designed for race use only.
BST Carbon fiber wheels have undergone an intensive programme of very stringent testing to verify their design and to confirm their strength and durability. Low mass and lowest Moment of Inertia results in a lower unsprung mass; this means faster cornering, later braking, improved acceleration – in all, faster lap times. Imagine the difference you'll experience from dropping 11.2 lbs off the weight of your bike! That's the difference in weight between the standard GSXR1000 wheels and the BSTs.
The front wheel was designed for a 150kg static load and the rear wheel for a 250kg static load (this translates into a bike with a total dry weight of up to 400kg). Modern sports bikes normally weigh between 160-220kg and race bikes rarely exceed 170kg, so these static load design parameters comfortably exceed normal conditions.
For road use, use the same tire pressure that you usually use. For suspension - if the suspension is working OK for you before you put on the BST wheels, you should not have to make adjustments. The carbon wheels make a huge difference to the smaller bikes so there are some things you need to know. If you get chatter on fast corners once you change to the carbon wheels that was not there with metal wheels, you should be able to tune it out with suspension settings, or you could add weight to the swing-arm. The reason is simple: the total weight working on the shock is a lot less and hence you are not working within the range of the rear shock. The shock works at about 5 - 10 hertz and the wheel at +- 30 hertz so the natural frequency can chase the chatter on the smaller bikes. By putting weight on the swingarm you have the same weight working on the rear shock while gaining the advantage of the much lighter rear wheel.
The BST wheels are designed to fit the same way the OEM wheels fit.
All internal bearings, spacers and seals pre-installed
External spacers, where required
Cush drive (rear conventional swing arm)
Sprocket carrier (rear conventional swing arm) where required – wheels can be purchased without a sprocket carrier if you wish (for race teams etc.)
You will need to buy a sprocket that fits the BST sprocket carrier
