BST Carbon Wheels - FRONT - RC 390


Product Description

NOTE* The FRONT wheel is a direct mount to the 2013-2016 model RC390 which has a smaller diameter bolt pattern on the rotor carrier/hub. If you would like to mount the FRONT wheel to a 2017+ RC390 you will need to purchase an OVERSIZED rotor (320mm) for a 2013-2016 model. However, your ABS ring will not be able to be used on the 2017+ models without modification. 

A carbon fiber wheel is possibly one of the best modifications that can be performed on any motorcycle. Weighing between 40 and 60 percent less than OEM wheels, BST wheels offer sport-bikes with sharper corner-carving abilities, faster acceleration, and quicker braking by weighing less than their production-bike counterparts. 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. A lighter rear wheel is easier for the shock to control properly, which leads to superior power application and much higher trap speeds in competition and track days.

Design: BST 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. Maximizing the molecular and structural properties of carbon fiber, BST has reduced spoke and rim weight without compromising their strength. Mass is therefore concentrated in the hub, reducing rotational inertia. This results in quicker acceleration and braking, allowing faster corner entry and exit speeds.

Manufacturing: BST designs the tooling, molds, wheel and hubs, then manufactures them in its state-of-the-art factory. Precision cutting machines, like those used in the aeronautical industry, ensure that the process is repeatable and meets the highest certification standards. BST uses only the finest “prepreg” carbon fiber, which is embedded in a top-secret resin matrix epoxy. Carbon-fiber layup is done in a dust-free and temperature-controlled “clean room.” The wheels are cured in a superheated steam oven, or autoclave, at 260 degrees and 85 psi. This produces the best material compaction and smoothest surface finish. Every step of this process is logged, the entire history of each wheel is stored and stamped with a unique serial number. To ensure the highest quality manufacturing processes and components, BST’s entire operation is managed under strict, new ISO 9002 standards.

Materials: BST works with it's suppliers to ensure we get the best and most advanced materials for our wheels. Since December 2011 BST has been using carbon from Umeco Structural Materials (USM) that is impregnated with the EF1808 resin system explained like this:

About BST: Established in 1992, BST is based near Johannesburg, South Africa. BST engineers and manufactures the world's finest carbon fiber motorcycle components from wheels and frames to fuel tanks and fenders, to the highest international standards. The standard equipment wheels on Confederate and Norton motorcycles, BST was also chosen to provide wheels and produce the carbon-fiber frame on the radical MotoCyz project. On the world stage, BST wheels have been proven at every level of FIM Grand Prix road-racing competition and have won 12 national championships. BST has sold more than 8,000 carbon fiber wheels around the world.

NOTE: Available in Gloss or Matte Clear Finish
