Tons of requests lately to ride a YZ426. @mikemoniz50 and @mjohnson28 had this 2002 YZ426 and said that they would give it to me if I could have fun on it, thanks boys! Full riding video up next 🔥 Yamaha came out with a YZ400F in 1998. In 2000 they turned it into a YZ426F. Then for 2003 it was turned into a YZ450F. Yamaha used a 5 valve head all the way through the 2009 model. Who has had a chance to ride one of these and what did you think of it? @redbullmotorsports @redbull @motosportinc @rdrco.inc #YZ426 #YZ426F #yamaha
