Kyosho Ultima RB7.5 2WD 1:10 Competition Racing Buggy EP Kit

New 13 mm aluminum big-bore oil shocks with X-ring seals provide smoother operation and improved control through fast corners, uneven sections and jump landings. The front and rear shock towers are now manufactured from 4 mm carbon fiber, while new aluminum rear bulkhead components and rear hub carriers increase rigidity and provide additional suspension geometry adjustment options.

The low center of gravity, mid-motor layout and rigid duralumin main chassis give the RB7.5 precise and responsive handling. An updated aerodynamic body, stronger rear wing and standard front wing allow the aerodynamic balance to be adjusted according to track conditions and driving style.

The RB7.5 is a true competition-level 1:10 RC buggy kit, offering extensive setup possibilities for different track conditions. It is also compatible with a wide selection of Kyosho Ultima setup and optional upgrade parts.
