With our recent post on no rules racing and the current flap over Matt Mladin's crankshaft, I thought this new ad for the Buell 1125CR was appropriate. The words are on a scale from, "Follow the rules" to "Write your own." The Buell is positioned well into the "Write Your Own" side of the scale. Neat and very timely.   … [Read more...]

Mat Mladin Disqualified Over Engine Rules

Replacing the 250s with something else makes sense as everyone moves away from 2 strokes but it will be interesting to see if the 600cc class will be a technology leading segment like the 800cc MotoGP … [Read more...]
