Hitec HS7115TH Karbonite Gear (3pcs)

The Kyosho Optima Mid Legendary Series – Koswork Edition (K.30622KE) revives the iconic 4WD racing buggy with a curated set of Koswork performance upgrades. Celebrated for its stunning 1987 World Championship debut, the Optima Mid retains its classic silhouette while receiving carefully selected updates for today’s electronics and power systems.

A belt-driven 4WD system delivers smooth, efficient power with an adjustable tensioner, while modernised 48-pitch gearing allows precise ratio tuning. Reinforcements such as a slipper clutch, FRP shock stays and a countersunk aluminium chassis enhance durability and control. With full ball bearings, hex hardware and updated steering belcrank with integrated servo saver, this vintage favourite is ready to be built into a sharp, contemporary performer.
