Yokomo have introduced a new carbon fibre rear shock tower for the YZ-2 CAL3 and YZ-2 DTM3. Based on the original 3 shock mounting holes, the new tower is machined from high-quality 4mm thick carbon fibre and comes with two additional holes, i. e. five shock holes overall as well as two wing mounting positions. The shock tower offers greater rigidity and strength from crash and allows more tuning possibility.
