Two Brothers Racing is bundling power-producing components for popular sportbikes into its new Power Plus Kits. The kits contain all of the parts needed to produce significant improvements in the performance to your sportbike, for racetrack use; no more mixing and matching components or trying to get them to cooperate with each other. The first kit—for the Yamaha YZF-R6—includes a TBR Black Series slip-on exhaust, a P1X natural aluminum silencer tip, a Juice Box Pro fuel management controller, an anodized black bolt kit, a muffler repack kit, a T-shirt and decal kit. TBR products are for off-road, closed-circuit course, race use only. Suggested retail is $782, from dealers. For more information, contact Two Brothers Racing, Dept. RW, 401 South Grand Ave., Santa Ana, CA 92705, (800) 211-2767, www.TwoBros.com.
