If you're interested in Vintage Motocross, and dirt bikes that were air cooled or stopping on drum brakes, or which came with left side kick starters, right side shifters and left side brake pedals, or if words such as Maico, Hodaka, Bultaco, Harley Davidson or Jawa interest you, then you'll likely enjoy the information and resources that you can actually use that are around here as there's even pics of old school Vintage and Evo bikes, circulating the motocross tracks as well as pics of these bikes on the stand or sitting around in the pits. We're talking 2 Stroke Smokers and 4 Stroke Thumpers included!! (Most of which are still alive and burning pre-mix or thundering across the straights and off jumps!!)
Mix all that with some truly old school pics of vintage bikes when they weren?t actually considered "Vintage" and it seems we've got something brewing here...

Also, Just for a heads up: This page is really just a hub to get you where you're going and below there will be links to other articles throughout this site which will help you with doing maintenance and other things to an older style dirt bike. Although most of the pages on this site are setup for those with modern machinery (which a lot of people with Vintage bikes have as well) There'll be links to direct you straight to the section(s) of each referenced page which are directly applicable to Vintage Motocross bikes and their Evolution / ?Evo? class cousins so finding what you're looking for will be that much easier.

If you're just now gaining interest in the Nostalgic end of Motocross you may quickly find out that all the bar banging action you see in modern motocross didn't come out of nowhere, as these guys on these vintage / classic bikes of yesteryear know all about racing and will initiate a block pass on you, stuff you into a corner or pinch you off on the corner of a jump or going into the first turn just the same as any modern class.

If you're interested in seeing American Vintage Motocross in all it's glory, with riders sporting Joffa masks and Authentic Retro gear, or if you're looking for some truly hard to find parts for some Vintage Motocross Iron, as well as if you have some parts you're wanting to sell... You don't want to miss the 2011 Vintage Motorcycle Days held at the Mid-Ohio Motorsports facility in Lexington, Ohio from July 22nd to July 24th 2011 where there will be fierce racing and Swap meets for those whom are interested in Motocross of Yesteryear and the Vintage Iron that the greatest riders of yesteryear were piloting. So, Let's get into it...
Okay, before getting too far ahead, If you're sort of at a loss and wondering what exactly defines a Vintage Motocross bike this outta help...

According to the AMA rule book, A Vintage Class bike is defined as:
A Machine Originally sold as a pre-1975 (and like design)year model motorcycle.

Okay, That's simple enough but what's ?and like design? all about?
Good question...
According to the AMA rule book for a vintage machine "Like Design" refers to the Frame, Swingarm and Forks being of a Period design and materials.

Note: If you should need to change the frame, swingarm or forks to a different configuration than the way they were designed during the period of time of which they were manufactured (or if these parts have been changed / modified before your ownership), you're going to need to file a written request for approval with the AMA at least 30 days before an AMA sanctioned event.

More info on this and other classes and rules can be found by checking out the AMA Rule book on the AMA Vintage Motorcycle Days Web Pages

Evo bikes are actually classified in 3 different ways:
Evolution 1which are machines which were originally sold as pre-1978 (and like design) models.Note: ?Like Design? in Evolution 1 Classes has the same meaning as for the Vintage Classes but is applicable to all bikes built prior to 1978. Evolution 2 classes refer to dirt bikes with air-cooled motors, drum brakes front and rear, and linkage-less rear suspensions.Evolution 3 classes refer to dirt bikes with drum-style brakes front and rear but may be liquid cooled and / or have linkage style suspension or forks that are not specific to the period of time which the motorcycle was built.
