Mazda MX-5 Spirit Racing Roadster 12R: 197 horsepower, 200 units.
The MX-5 Spirit Racing Roadster 12R is limited to only 200 units in Japan, boasting a power output of 197 horsepower thanks to improvements in intake/exhaust and camshafts; a 6-speed manual transmission, rear-wheel drive, and Bilstein shock absorbers.
According to Carscoops, Mazda only produced 200 MX-5 Spirit Racing Roadster 12R models for the Japanese market, while the number of applications exceeded 9,500. The supply-demand imbalance demonstrates the appeal of the first model from Mazda Spirit Racing – the new high-performance division replacing MazdaSpeed.
New power for the MX-5: 197 horsepower from a 2.0L naturally aspirated engine.
The biggest difference in the 12R lies in its power. Using the same 2.0L naturally aspirated four-cylinder engine as the standard version, the 12R delivers 197 horsepower instead of 181. This increase comes from a series of refinements focused on the engine's breathing: a new intake port, a retuned exhaust system, and upgraded camshafts.
These changes make the 12R one of the most powerful Miatas ever. With a rear-wheel-drive configuration and a single 6-speed manual transmission, the Mazda Spirit Racing upgrade package aims for a pure driving experience, optimizing mechanical responsiveness rather than relying on turbocharging.
Chassis and suspension: deliberate fine-tuning
Mazda equipped the Spirit Racing Roadster with Bilstein shock absorbers, along with specific tuning to improve handling. Bilstein is a familiar choice in performance-oriented configurations due to its tight body control and stable rebound. On the 12R, the goal is to maintain the MX-5's inherent agility but elevate control during cornering and load changes.
The combination of a naturally aspirated engine, a 6-speed manual transmission, and rear-wheel drive allows the driver to interact directly with the vehicle. On roads requiring precise gear changes, the 12R promises to take advantage of the engine's wide rev range and linearity to maintain a stable pace.
The 12R's distinctive look: an emphasis on performance.
The 12R version comes in Aero Gray paint, with darker gray accents on the front splitter, side skirts, and rear wing. This color scheme emphasizes aerodynamic purpose and performance rather than mere decoration.
Inside, the Roadster 12R features Alcantara-upholstered sports seats and four-point seatbelts. The seats provide better support during high-speed cornering, while the four-point seatbelts increase body stability – a detail that aligns with the track-focused spirit of the 12R package.
Two configurations, two power levels
Mazda introduced two versions: the standard Spirit Racing Roadster and the 12R. Both share the same 2.0L naturally aspirated engine platform; the standard version delivers 181 horsepower, while the 12R achieves 197 horsepower thanks to the aforementioned upgrades. Both use a 6-speed manual transmission and rear-wheel drive, targeting drivers who prioritize mechanical interaction and a pure driving feel.
The clear distinction between the 181 hp and 197 hp power outputs also helps Mazda Spirit Racing position the 12R as an option for users who need more performance while still maintaining the "less is more" philosophy of a lightweight roadster.
Price, quantity, and market
The standard Spirit Racing Roadster starts at 5.265 million yen (approximately $34,400) and is limited to 2,200 units. The 12R version is exclusive to Japan, with only 200 units produced, starting at 7.612 million yen (approximately $49,700). With over 9,500 registrations, access to the 12R is very limited; customers who haven't secured a spot will likely opt for the standard version or wait for later batches if available.
As the flagship product of the Mazda Spirit Racing line, the limited-production strategy demonstrates how Mazda controls the experience and market response before expanding its high-performance portfolio.

Conclusion: A focused tuning package, true to the roadster spirit.
The MX-5 Spirit Racing Roadster 12R doesn't change the core philosophy of the MX-5, but fine-tunes precisely where it will make a difference on the road: technically sound power increase, Bilstein shock absorbers, and high-intensity seat and harness sets. Within the 200-car production run for Japan, the 12R is both a showcase of Mazda Spirit Racing's prowess and a valuable collector's item for those seeking a powerful, manual, rear-wheel-drive Miata.
With its standard version, the MX-5 Spirit Racing Roadster retains the "true MX-5" technical specifications and a more accessible price point. These two configuration tiers allow Mazda to cater to a wide range of needs: from riders who appreciate basic roadster performance to those demanding more performance while still prioritizing human-machine interaction.
