Where the Sport S sits in the lineup
The Sport S is the most street-friendly model in the Sport Series, sharing its core mono-tube architecture with the rest of the range but tuned for real-world road conditions. Drivers who need a more competition-focused setup can step up to the Sport R, while those wanting independent compression and rebound adjustment should consider the Sport TN.
