- Bolt Kit FAQs What are the primary technical differences between the R21 Ultra and the R25 Ultra?
Both models share a zero-cogging flat-wire motor, a 21-bit magnetic encoder, and advanced FFB algorithms. The R25 Ultra adds higher sustained torque (25Nm) and a built-in true torque sensor (0.1% accuracy, up to 2 kHz sampling), delivering finer input fidelity and faster torque response. The R21 Ultra focuses on 21Nm sustained output and excellent thermal stability as a value-oriented, high-performance option. What is the benefit of the built-in torque sensor?
The built-in torque sensor continuously measures actual output torque at a 2kHz frequency with 0.1% accuracy. This allows the base to deliver “true torque feedback," meaning what you feel is directly tied to the motor’s real physical output—not an approximation. It enhances steering precision, ensures linear response, and improves vehicle control during oversteer or traction loss. How does a true torque sensor affect driving feel?
A true torque sensor measures the torque you apply directly (rather than inferring it via motor currents), resulting in lower measurement error, faster response, and more faithful reproduction of subtle road and steering cues. For competitive or pro users, this increases control fidelity and repeatability—key benefits that justify the R25’s premium positioning. Who is the R25 Ultra designed for?
The R25 Ultra is engineered for advanced sim racers and esports professionals who demand uncompromising torque, precision, and durability. It’s ideal for competitive environments, heavy GT and Formula racing, and long endurance sessions where sustained torque output and thermal stability are critical. Does the R25 Ultra run hotter or louder due to higher torque?
No. The R25 Ultra features MOZA’s upgraded intelligent thermal management system with real-time temperature monitoring. Its high-efficiency flat-wire motor design ensures superior cooling and quiet operation, even under sustained 25Nm output.accordion-btn background:#f5f5f5; cursor:pointer; padding:16px; width:100%; text-align:left; border:none; outline:none; font-size:16px; font-weight:bold; display:flex; justify-content:space-between; align-items:center; margin-bottom:4px; font-family: inherit;.accordion-btn.plus font-size:20px;.accordion-panel display:none; background:#fff; padding:16px; margin-bottom:8px; font-family: inherit; document.querySelectorAll(".accordion-btn").forEach(btn=>btn.addEventListener("click", ()=>const panel=btn.nextElementSibling; const plus=btn.querySelector(".plus"); if(panel.style.display==="block") panel.style.display="none"; plus.textContent=" "; else panel.style.display="block"; plus.textContent="–"; ); )
