About this product
The Kyosho Ultima SB Dune Master 2WD 1:10 EP Kit (item K.34312B) is Kyosho’s Ultima SB (vintage 1/10 RWD buggy) — a 1/10 RWD competition buggy for racers and enthusiasts who want a kit-built chassis.
Sold as an unbuilt kit, this version lets you specify the motor, ESC, servo, radio and battery to suit your class and driving level. The Ultima platform has a long heritage at IFMAR worlds and continues to be supported with current Kyosho race spares and hop-ups.
The Ultima line covers everything from re-released vintage buggies through to current race-class chassis — one of Kyosho’s longest-running competition platforms.
Why racers pick the Ultima SB
- RWD competition buggy platform
- Race-spec geometry — tuneable camber/toe/ride height
- Oil-filled shocks with full ball-bearing drivetrain
- Race-grade chassis — aluminium plate, hardened drivetrain components
- Kit format — specify your own motor, ESC, servo, receiver and battery
