Our new Beta 4 shoes clutch system has all kinds of powerful new features — like the best balance between durability, traction, and drivability — that require exceptional mechanical properties to experience fully. So we gave it our best: the Super 7075 aluminum.
Even the 34mm flywheel uses 7075 — allowing for a lightweight and robust design. In addition, steel flywheel pins offer the greatest strength and durability.
More racing. Excellent traction and lowest fuel consumption on all surfaces.
