Description Technical Specs
Kyoso Ultima RB5 Logo SP


The new Kyosho Ultima RB5 SP is the latest version of one of the most popular 1/10th competition electric racing buggies on the planet. With a bunch of new parts and setup changes that come from the culminated experience from world champion factory drivers like Jared Tebo and the Kyosho engineers, this Ultima Kit is ready to win right out of the box! world. This type of development, along with the uncompromising manufacturing standards of Kyosho, the vast experience that can only be gained from decades of high level competition, makes the Ultima RB5 SP a strong choice as the car to beat for the 2009 season.

The improvement comes with a list of changes to the Ultima:
  • Long Rear Suspension Arms - The RB5 SP features rear suspension arms that are 2mm longer than the arms used on the original buggy, which are the same arms that are standard on rear of the Lazer ZX-5 FS. The longer arms, combined with other changes made to the rear suspension, give the SP better and more consistent traction through the corners and better bump handing, especially on high-bite tracks.
  • Rear Suspension Mounts and Transmission Housing - The lower rear suspension mounts on the chassis are revised to accommodate the longer suspension arms. The IFMAR legal maximum width is maintained by moving the suspension mounts 2mm towards the center of the chassis. The transmission housing is also modified to fit the new suspension mounts.
  • Low Profile Rear Shock Tower - Reducing the height of the rear shock tower slightly lowers the center of gravity, which improves cornering ability, and by reducing the height of the shock tower in relation to the wing and wing mount, it offers addition protection against crash damage.
  • Velvet Coated Shocks - The already legendary Kyosho shocks
  • Hard Rod Ends - The rod ends feature a new, stronger material that is more durable and resists contamination from dirt. This means that the rod ends stay tighter and are less likely to be damaged or separate from the ball stud in the event of a hard crash.
  • Revised Rear Hubs - Factory drivers have determined that only one of the hinge pin holes was ever used in the original RB5 wheel hubs, so the extra hole was eliminated for the new SP Edition. Combined with a new, more durable material, these hubs are not only much stronger, they're also lighter and the new geometry produces more stable handling characteristics
  • Chrome Moly Turnbuckle Linkage - Use of a stronger material means the new turnbuckles can be made lighter and stronger than the original steel turnbuckles. The new turnbuckles feature a 3mm square adjuster, which further reduces weight.
  • Orange Front Shock Springs - The kit now includes the popular orange front shock springs, which produce better suspension action over the bumps and more precise steering control in the corners.
  • Newly Designed - Chiseled lines combine with smooth, flowing sections to create a body that is not only attractive and boldly styled, it also provides greater down-force in combination with a larger rear wing for increased traction and greater high-speed stability.
Standard Features
  • Chassis - specially formulated carbon fiber composite for the best balance of performance and durability.
  • Transmission - Features an externally adjustable three gear design with an internal ball differential that uses standard 3/32 inch diff balls and 1/16 inch thrust balls. Includes tight fitting molded dust cover to protect pinion and spur gear.
  • Rear Suspension - The arms are symmetrical so a single replacement arm can be used on either side of the car. The inside of the arms are attached to the chassis using separate suspension mounts, which will allows anti squat adjustment. Vertical ball studs for both ends of the upper link suspension geometry can be fine tuned with shims.
  • Front Suspension - Long suspension arms connect to a narrow front mount, which can be set for 25 or 30 degrees of hinge pin angle. Like the rear arms, a single replacement arm can be used on either side of the car.
  • Offset steering hubs - Floating axles ride in bearings that are mounted in the hub for more responsive suspension. The front track width is also easily adjusted.
  • 12MM Hex Wheel Hubs - 6 contact points spread the load on the wheel to prevent stripping and the larger, flat mounting surface keeps the wheels running straight and true.
  • Steering Assembly - Steering bell cranks are mounted on the chassis at the same angle as the suspension arms to eliminate bump steer and produce more accurate Ackerman geometry throughout the entire range of steering motion.
  • Captured Hinge Pins - The hinge pins are much more secure and less likely to come loose.
  • Low Profile Shock Towers - The front shock tower is mounted as far back on the chassis as possibly, as are the shocks, to keep the mass as low as possible.
  • Threaded Aluminum - The shock body consists of a top cap, threaded body, and a lower cap. The threaded adjuster features an Oring that prevents the pre-load settings from moving.
