TTX25 MkII

Öhlins understands the importance of relationships from beginning to end, from racers in training to experienced veterans. It’s for this reason that we offer the TTX25 MkII FSAE: a product centered in the Formula SAE/Formula student collegiate design organizations’ demands. The TTX25 MkII FSAE uses modern twin tube technology, in a small package. The 4-way externally adjustable damper is completely serviceable by the end user, and rebuild and revalve kits are available to make the task easy. Also available are springs, spare parts, specialty tools, dynamometer plots, CAD models, and other technical information.
