Yamaha’s V-Four-engined VMax may be the ultimate musclebike, but tipping the scales at nearly 700 pounds, it sure is heavy! Blackstone Tek’s five-spoke 18-inch carbon-fiber wheels weigh a claimed combined 25.2 lb.—8.25 lb. for the front and 16.95 for the rear—and are said to dramatically improve handling. Aluminum hubs are CNC-machined for a perfect original-equipment fit, and the clear-coated carbon complements the VMax’s aluminum trim. Per-pair price is $5290; add $150 for ceramic bearings.
