2002 Yamaha YZ426F, This is a 2002 Yamaha YZ426F street legal with a license plate... A must see with lots of parts for baja designs. Just serviced - Four Strokes. Five Titanium Valves. One Bad Mother. "Could the YZ426F be perfect?" Motocross Action magazine asked in a recent test. Well, we’d of course have to say "yes," but you’d expect that from us. So we’ll just let this milestone of MX engineering, winner of three straight "Four-Stroke of the Year" awards, speak for itself. And we’ll start with what’s arguably its most devastating asset: 426cc of liquid-cooled, 5-titanium-valved, four-stroke single, bearing newly remapped ignition for more precise spark - and performance that’s quicker and harder hitting than ever.
