Kyosho Ultima RB7SS Stock Spec Competition Buggy

Kyosho Ultima RB7SS Stock Spec Competition Buggy

If you’re into spec racing, Kyosho has released a version of their RB7 buggy for stock motor class competition. The Ultima RB7SS Stock Spec kit is a 1/10-scale, two-wheel-drive competition buggy kit featuring lightweight internal components and an array of updated elements.

Among the updated pieces are lightweight, aluminum driveline elements which aim to reduce rotating mass. Weight has also been reduced from the front axles, thanks to their anodized aluminum construction.
