THE FLAGSHIP MODEL
Redspeed Kart introduces, for the single-speed, shifter and DD2 categories, the new top-range chassis: the RX RR. Climax of the evolution of the work of the OTK Kart Group R&D department, the new RX has some interesting new features
Ongoing development
HIGHEST PERFORMANCE
The RXT, the new flagship chassis of Redspeed Kart, is the peak of innovation and experience gained in the field by OTK Kart Group. Actually, the new RXT keeps faith with the company mission "Designed, Engineered, Manufactured, 100% Made in OTK - Italy" at the base of all OTK Kart Group products. The rigorous control of the entire design and production chain, thanks also to the use of automated processes that guarantee extremely high-quality standards, has always been the distinctive element of the Italian company.
M11 Fairing Kit
SCULPTED BY THE WIND
OTK Kart Group R&D department has been for years a pioneer in the aerodynamic research and development of its karts through wind tunnel analysis and CFD computer simulation. This relentless research activity has led, over time, to the launch of revolutionary solutions in the field of fairings such as the M7 front spoiler, with its innovative design and ability to reduce aerodynamic resistance, resulting in increased performance. This model, now made of black plastic, is now complemented by the new M10 kit for the RX RR. It includes the new side bumpers, which are lighter in weight and smaller in size, to the benefit of performance and better cooling of the rear tyres. But that's not all, because the front spoiler and rear protection have also been renewed in order to meet the increasingly demanding requirements in terms of FIA safety regulations.
BWZ Brake system
WINNING BRAKING SYSTEM
Confirmed for the new RXT, in its single-speed version, the BWZ braking system that has significantly contributed to the achievement of excellent results in the most prestigious races in the world: just consider that the braking system signed by OTK Kart Group has equipped both karts winners of the 2021 titles for the single-speed senior and junior categories. The rear brake caliper, forged in one piece, is equipped with a stroke recovery system and features two D. 34.5 mm pistons. This is combined with a two-piston pump and a brake line with outer cover stainless steel braid, PTFE inner tube. The caliper and brake pump are made of Ergal, a material that stands out for its excellent mechanical strength, which is further increased by the hard oxidation process that reduces wear on the moving parts.
Driving position
COMFORT AT FIRST PLACE
Driving comfort is fundamental for the performance of every driver. This aspect plays a central role in the entire development process carried out by OTK Kart Group for the RX RR, which offers several new features aimed at refining even the smallest details. To be highlighted, in fact, is the standard supply of a footrest that allows a greater range of adjustment and, in addition, new seat supports. These solutions are in addition to the already well-known HGS steering wheel, equipped with high grip and comfort rubber grips, and the inclined hub, for a fully ergonomic driving position.
BWZ and BSZ Brakes
WORLD MIX
OTK Kart Group produces according to well-defined standards: the use of selected materials of the highest quality and their processing using automated machines and processes that ensure full reproducibility of each component, always guaranteeing the highest quality parameters. These principles are more fundamental than ever when it comes to braking systems for shifter categories, classes in which braking capacity plays a primary role in performance. With the arrival of the RX RR, Redspeed Kart proposes as standard a new system for the shifter classes called BSZ, equipped with brake pumps with larger diameter pistons that make the braking even more modular. For the DD2 version, instead, the reference system remains the BSS only, equipped with single-piece calipers, front with four D. 22 mm pistons and rear with two D. 34.5 mm pistons.

doesn't whistle as loud as other chuckit balls I've seen, but a good ball.
makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting.
but it flys good and the dog loves to chase it.
he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it.
I'll likely buy another at some point ... just wish it was a little louder when flying.

Blue ball, my dog likes blue.
Just a ball right? Evidently not! My dog won’t chase an orange chuck it ball or the glow in the dark ball- only the blue one 🤷🏼♀️

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
