Vintage Motocross at Wildcat Creek MX

I attended my first vintage motocross race at Wildcat Creek MX this August. The race is part of a vintage series called Midwest Vintage Motocross. You can read more about them on their official website here. You can check out the track’s website by following this link. Wildcat Creek MX is just west of Lafayette, Indiana. It is a 2-day event featuring both modern and vintage dirt bikes. It appeared the majority of the vintage bikes were from the ’80s, although there were a few from the ’70s as well. We arrived during practice in the morning, right before the first race of the day was to begin.

Going through the pits we pasted rows of trucks and trailers, with classic bikes from all over the world, such has Husqvarnas, Maicos, Yahamas, Suzukis, Hondas, Kawasakis, a Penton and a CZ. The Wildcat Creek MX track is built on a small hill, and at the bottom of the hill is a tree line that the course briefly disappears behind. It utilizes the natural terrain. The jumps are exclusively made up of forgiving tabletop jumps, which is good for the shorter suspension travel of the vintage bikes. There are several light evaluation changes, as well. The infield is accessible via a tunnel under one of the larger tabletop jumps which makes the track very accessible to spectators. It’s a somewhat lengthy course. We hung out just after the first turn. This gave us a great view of the start of the race, and several other parts of the track as well. Wildcat Creek MX even has an indoor pace to eat.

It was interesting to see vintage bikes on the track, along with modern ones, as multiple classes were run at the same time. In some of the races, there was more than a 30-year difference in the ages of the bikes. It seemed that almost every race we watched had a mostly full starting line. It was refreshing to hear so many 2-strokes on the track. As the motos went on a light drizzle slowly turned into a total downpour. We left around that time. I’m looking to returning to watch some more vintage motocross racing. It was cool to see so many valuable classic bikes, on the track doing what they were made to do.

The Evolution of the Dirtbike.

                Although its purpose and general design has remained the same for over 50 years, the dirtbike has evolved considerably. With its evolution, the sport of motocross has changed with it. The dirtbike’s improvements often occur alongside its road-going counterparts. No matter how much dirtbikes change, one thing is for sure; manufacturers will continue to improve their bikes to get that competitive edge.
The 60’s: The Early Days.
                In the early days of motocross, the bikes often resembled something you might find on the street. Knobby tires helped bikes get traction off-road. Fiberglass fenders appeared in the 60s, making the bikes lighter then the steel they replaced. Motocross races of the time had smaller jumps then what is seen today, and they often incorporated natural terrain into the track.

The 70’s: Rise of the Factory Teams.
                Motocross’ incredible popularity meant that a wide range of manufacturers were not only making dirtbikes but also fielding factory-backed pro motocross teams. Manufacturers from all over the world began making motocross bikes bringing with them innovations. Harley Davidson even got in on the act for several years. During this time, bikes saw new materials introduced to bikes such as plastic and aluminum, which meant better performance. During the 70s aluminum gas tanks appeared, as well as aluminum wheels helping the bikes to become lighter. Plastic fenders appeared as well. Factory “works” bikes appeared at professional races, with high-performance modifications not found on production bikes, showing how important the sport was for manufacturers. An example of this was Honda and their Mugen performance division.

The 80’s: Changes for Bikes and Tracks.

Few eras saw such radical changes in motocross bikes then the 1980s. One of the significant improvements to come to dirtbikes during this time was the suspension. Bike suspensions got longer travel. The twin rear shocks were replaced by the single mono-shock. Disc brakes appeared as well. Gas tanks became plastic around this time. By looking at motocross’ indoor cousin, Supercross, it becomes clear how much the bikes advanced during this time period. When the first Supercross race was held in the mid 70’s the track closely resembled motocross tracks of that era, consisting of a few jumps. By the 80s, the number of jumps had grown in size and amount. Liquid cooling came about as well during this era.        
                As supercross jumps got bigger and bigger bikes evolved as well. One of the big changes came in the form of the inverted or “upside-down” front suspension. Although not universally adopted, the aluminum frame was another significant innovation that was utilized by almost all of the major manufacturers replacing steel ones. Interestingly spoke wheels have remained a constant in motocross for over 50 years, with a few deviations from it. A more recent change is the move to electronic fuel injection. As bikes continue to evolve, manufacturers are always looking for ways to gain an edge on their competitions, but one thing remains the same, great racing.
