Up to 50% lighter than original equipment rims, the BOOST wheels are a more aggressive-looking alternative to Rotobox's popular RBX2s. The BOOST's thinner spokes have larger "windows" between them than the current RBX2's smooth, rounded ones. BOOST spokes are also ribbed for additional torque resistance and have invisible joints that make them appear seamless.
These hollow BOOST spokes are also lighter, stronger and even more aerodynamic than the those on the RBX2 wheels, which rolled up to 226 mph on a Brock's-modded Kawasaki Ninja H2 in a record-setting run from a standing start in just one mile.

Along with offering incredible straight-line stability in such extreme conditions, lightweight Rotobox wheels also enable nimbler handling, improved suspension compliance, more effective braking, greatly reduced unsprung mass and less gyroscopic effect in cornering.
Much of this is due to the BOOST's exclusive, 3-Component Composite, a complex formulation of carbon and epoxy, reinforced with stainless-steel wire. The 2.5 mm-thick wire is integrated into both sides of the rim, increasing impact resistance in the most critical areas. The world's only one-piece, carbon-monocoque wheels, Rotobox products are manufactured utilizing a high-pressure Resin Transfer Molding (RTF) process that consistently turns out flawless, watertight rims.
The BOOST's carbon-fiber surfaces beg for artistic personalization. They can be ordered painted up in Rotobox's palette of colors, with splashy graphics, stripes or any logo. To protect each masterpiece, the wheels come in a choice of matte or glossy finishes covered by a UV-blocking clear coat that accentuates their carbon weaving.
Direct replacements for stock rims, model-specific Rotobox wheels come in convex and symmetrical designs for motorcycles with dual- or single-sided swingarms. Their CNC-machined 7075 T6 aluminum billet hubs, disc and sprocket carriers can be customized with optional anodizing colors.
BOOST wheels are supplied with a cush drive, spacers, easy-access, 90-degree aluminum billet valve stems and a choice of ceramic or steel bearings. They're DOT- and JWL-approved, having met JASO T203-85 safety standards that include lab-based tests measuring cornering, radial, torsional and impact performance.
America's foremost carbon-fiber wheel expert, Brock's Performance has been selling and providing aftercare support for composite wheels since 2009. Brock's is now carrying the entire line of Rotobox's BOOST and RBX2 wheels for most popular sportbikes, in 3.5- and 6.0-inch sizes.
