On Thursday's Fly Racing Moto60 show Steve Mathe's guest David Pingree reveiled that there will be a three round "Tripple Crown" 125 dream race as half time entertainment at select Nationals this year.

According do Pingree the Glen Helen, Thunder Valley and Washougal rounds will host exhibition rounds of the 125 Dream Race.

Having been at Washougal last year for this event I can tell you that a full 40 rider gate of 125's sounded amazing and was a big hit with the spectators.

We have worked hard to recover as much of the original content of this site that was lost in a server crash as possible. Some of the images were forever lost but the vast majority of the original site is back, including a little over 59,000 posts in the forum, some of it truly unique and valuable stuff.

Take a look at the Archves for as much of the original TSM content (most!) as we were able to recover.

We invite you to enjoy what we have brought back and look forward to adding several new features in the coming months along with interesting and informative new content.

Welcome and please check back frequently as we will be bringing new content and new features online as fast as we can!

A few years ago, it was suggested to me that it might be a good idea if I learned how to ride a motorcycle, just the basics, so that if something happened while we were out on our street bike I would know what to do.

One of the instructors was an avid dirt bike rider, along with her daughter. We talked.
