To clarify compatibility with your 2025 Nightster Special, it uses Harley-Davidson's RevMax engine platform, which has limited Dynojet support. While we do offer tuning support via the Power Vision 3 (PV3-15-04) and Power Vision 4 (PV4-15-04) for the RH975 Nightster model (with the Revolution Max 975 engine), compatibility with the RH975S Nightster Special is currently unconfirmed.
Since compatibility for your specific model is uncertain, speed limiter removal through Dynojet tuning solutions may not be available. For performance modifications or speed limiter removal on your 2025 Nightster Special, explore options outside of Dynojet's current product line. Consider contacting your local Harley-Davidson dealer or independent performance shops that may have alternative solutions for RevMax-equipped motorcycles. You can also check back with us periodically at dynojet.com or contact Customer Service at customerservice@dynojet.com for updates on compatibility for your model.
