Motorcycle Racing Events at Road America
Road America’s motorcycle racing calendar is built around two distinct forms of competition: professional MotoAmerica road racing on the facility’s four-mile circuit and the recurring Road America Supermoto Series at the Briggs & Stratton Motorplex.
These events offer very different racing experiences. MotoAmerica brings nationally recognized riders, factory-supported teams, high-performance production-based motorcycles, and multiple championship classes to the main road course. Supermoto places riders on a shorter, more compact circuit that combines tight paved sections with mixed-surface features and frequent changes in direction.
Both events return to Road America regularly, giving motorcycle racing fans opportunities to watch competition on two circuits with very different layouts and demands.
MotoAmerica Superbikes at Road America
MotoAmerica Superbikes is Road America’s largest annual motorcycle racing event.
The weekend includes professional practice, qualifying, and racing on Road America’s 4.048-mile, 14-turn circuit. The course is known for its long straightaways, substantial elevation changes, high-speed sections, and demanding braking zones.
Those characteristics make Road America especially well suited to motorcycle road racing. Riders must manage acceleration and top speed on the straights while remaining precise under braking and through technical sections of the course.
MotoAmerica weekends generally feature competition on multiple days, with qualifying establishing starting positions before the primary races. The result is a full weekend of on-track activity rather than a single headline race.
Motorcycle Classes at MotoAmerica
MotoAmerica brings several motorcycle racing classes to Road America. The exact lineup may change between seasons, but recurring and recent categories have included:
- Superbike
- Supersport
- King of the Baggers
- Twins Cup
- Royal Enfield Build. Train. Race.
Each class has different motorcycle specifications, performance levels, and competitive characteristics.
Superbike
Superbike is the premier class of the weekend. These motorcycles are based on production sportbikes but are extensively prepared for professional competition.
Teams modify and develop components such as suspension, brakes, electronics, exhaust systems, bodywork, and engine performance within the championship’s technical rules.
At Road America, Superbike riders can reach very high speeds on the long straightaways before entering major braking zones. The circuit therefore tests both outright motorcycle performance and the rider’s ability to brake consistently, carry speed through corners, and accelerate effectively onto the next straight.
Supersport
Supersport competition uses middleweight production-based motorcycles. Although the machines generally produce less power than Superbikes, the racing can be extremely close.
Riders must preserve momentum, use precise cornering lines, and avoid mistakes that would allow nearby competitors to gain position. The class often demonstrates that lap time depends on far more than engine output.
For spectators, Supersport provides an opportunity to compare drafting, braking, line selection, and corner-exit performance among closely matched motorcycles.
King of the Baggers
King of the Baggers places heavily modified American V-twin touring motorcycles into a professional road-racing environment.
These motorcycles retain the recognizable appearance of large baggers while receiving substantial racing modifications. Their size, sound, acceleration, and movement under braking make the class visually distinct from conventional sportbike competition.
Road America’s long circuit gives the motorcycles room to build speed while placing significant demands on braking systems, suspension setup, tires, and rider control.
Twins Cup
Twins Cup uses lightweight and middleweight motorcycles powered by twin-cylinder engines.
Compared with the premier classes, Twins Cup places additional emphasis on momentum and corner speed. Riders cannot rely solely on acceleration to recover from a poor corner entry or missed apex.
Close drafting and frequent position changes can make the class particularly engaging for spectators.
Build. Train. Race.
The Royal Enfield Build. Train. Race. program combines motorcycle preparation, rider development, and competition.
Participants build or prepare their race motorcycles, receive training, and compete at selected MotoAmerica rounds. Its inclusion adds a rider-development component to the weekend and gives spectators a look at racers progressing through a structured competition program.
How Road America Influences the Racing
Road America’s layout creates several distinct challenges for motorcycle racers.
The circuit’s long straightaways place a premium on acceleration, aerodynamic efficiency, and the ability to draft another rider. Drafting allows a following motorcycle to use the reduced air resistance behind a competitor before attempting a pass.
The ends of those straightaways create significant braking opportunities. Riders who can brake later without missing the corner may gain position, but excessive entry speed can compromise the line or cause the rider to run wide.
Elevation changes also influence what riders can see and how motorcycles behave. Braking, steering, and throttle inputs must account for rises, descents, and sections where the next portion of the course is not immediately visible.
Because the circuit is more than four miles long, riders and teams must also manage a larger number of variables than they would on a compact track. Tire performance, fuel strategy, weather, and changing conditions can affect different sections of the lap in different ways.
Watching MotoAmerica at Road America
Road America allows spectators to move between multiple viewing locations rather than remaining in one permanent grandstand.
Long straightaways provide a clear view of acceleration and braking. Corner areas make it easier to observe lean angle, line selection, overtaking attempts, and differences in rider technique.
Watching from several areas during practice or qualifying can help visitors choose where they want to view the main races.
The MotoAmerica event also typically provides access to the race paddock. Fans may see teams inspecting motorcycles, making suspension changes, fitting tires, repairing bodywork, reviewing data, and preparing for the next session.
Paddock access helps explain the technical work behind the racing and gives spectators a closer view of the motorcycles than they would receive from trackside viewing alone.
Vintage MotoFest and Supporting Activities
Vintage MotoFest is held alongside the MotoAmerica racing weekend, but it should not be confused with a separate professional racing series.
It is a motorcycle-focused festival that adds displays, a ride-in bike show, vendors, demonstrations, and entertainment to the race weekend. Motorcycle categories may include vintage machines, café racers, sportbikes, customs, scooters, military motorcycles, and restored race bikes.
The festival broadens the weekend beyond current championship racing by giving visitors an opportunity to examine motorcycles from different eras and styles.
Road America may also offer activities such as stunt shows, rider appearances, autograph opportunities, and controlled motorcycle touring sessions. These activities support the main MotoAmerica program but are not competitive races.
Because supporting attractions can change, visitors should review the current event information before attending.
Road America Supermoto Series
The Road America Supermoto Series provides recurring motorcycle competition at the Briggs & Stratton Motorplex.
Unlike MotoAmerica, which uses the full four-mile road course, supermoto races take place on a compact circuit designed to produce frequent braking, turning, passing, and surface transitions.
Supermoto motorcycles are generally lightweight machines derived from off-road or motocross designs and adapted for racing on pavement and mixed surfaces. They typically use road-oriented wheels and tires while retaining the upright ergonomics and maneuverability associated with dirt bikes.
Road America’s series includes multiple races during the season, with points-paying events, a non-points race, and a Supermoto Shootout.
What Makes Supermoto Racing Different?
Supermoto combines techniques from road racing and off-road motorcycle competition.
Riders may encounter:
- Tight paved corners
- Heavy braking zones
- Fast direction changes
- Dirt sections
- Jumps
- Varying traction levels
- Short acceleration areas
The frequent transitions require riders to adjust braking, body position, throttle application, and line selection throughout each lap.
Because the circuit is compact, spectators can often see a larger portion of the racing from one location. The shorter lap also brings the riders past viewing areas more frequently than on the main road course.
Although speeds are lower than in MotoAmerica Superbike competition, the close spacing and repeated passing opportunities can make supermoto highly active and easy to follow.
Supermoto Classes and Competitors
The Road America Supermoto Series accommodates several racer categories and motorcycle types.
Class structures may account for factors such as engine size, rider age, experience, motorcycle design, or competitive level. Mini-bike and youth categories may also be included depending on the current season’s rules.
Competitors must follow the series rulebook, technical regulations, registration procedures, and safety-equipment requirements. Points from designated races contribute toward seasonal championship standings.
Because the class structure and requirements can change, prospective racers should consult Road America’s current Supermoto information rather than relying on previous-season rules.

Two Forms of Motorcycle Racing at Road America
Road America’s recurring motorcycle racing events give fans two distinct ways to experience competition.
MotoAmerica places professional riders and production-based racing motorcycles on the four-mile road course, with classes ranging from Superbikes and Supersport machines to baggers and twin-cylinder motorcycles.
The Road America Supermoto Series offers shorter, more concentrated competition at the Motorplex, where lightweight motorcycles navigate tight turns, mixed surfaces, and rapid changes in traction.
Vintage MotoFest, paddock access, motorcycle displays, and other fan activities add to the MotoAmerica weekend, but the racing itself remains centered on MotoAmerica and the Supermoto Series.
