This is from Motorcycledaily.com today............... Why is Everts Still Racing a Steel-Framed YZ450F? By Dirck Edge With everyone expecting Yamaha to introduce aluminum-framed four-stroke motocrossers next year, why is World champ Stefan Everts still riding a bike with a steel frame (pictured above)? You may recall that Everts tested an aluminum-framed race bike a few years ago, and switched back to steel. Aluminum-framed YZ four-strokes have been spotted racing in Japan, and looking like pre-production models. Normally, you would expect the MX1 champion to be aboard next year's pre-production machinery. We should know within a few week's time whether Yamaha is, in fact, introducing aluminum-framed four-strokes to the motocross market next year. The announcement should come in early to mid-June.
