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.

Work great, no morning groggy, made in USA
Flavor Name: Peppermint
These make me sleep like a baby! I am 52 and often could not turn my brain off to go to sleep or stay asleep at night. About 30-45 minutes after taking these my head hits the pillow and I’m out! I take 3 tablets / 15 mg. No groggy feeling in the morning. My previous experience with melatonin had been gummies - 10-12 mg and did not work as well. Taste was also inconsistent. These are a nice peppermint, like the circle-O candies we ate as a kid. A little chalky but not bad. They don’t dissolve as fast as I thought but directions say ok to chew so then they dissolve very quickly. I also like that company is fully USA for development and manufacture. Many of gummies are not. The tablet format is also very convenient to pack for travel. I have not tried full pill format by any manufacturer.

Like the dissolvable feature
Flavor Name: Peppermint
Cardiologist recommended one tablet nightly 30 minutes before bed to protect the lungs from covid. His other recommendations were standard protocol. Had never heard of this but know that melatonin is supposed to help with sleep. Had tried melatonin for sleep, at higher strength, but effect wore off after a week. Suprisingly, this seems to help with sleep as well. Large count at reasonable price.

Sleep aid that helpd.
Flavor Name: Peppermint
I purchased these because I understand that the natural production of melatonin decreases drastically after the age of 40. I have been using another brand that much more expensive for a lower dosage. I read the other reviews and decided to give these a try. I have been taking them for about 30 days. I think, I have a good understanding of the pills. It appears that the other brand had a more consistent effect. They sublingual and you would feel drowsy after about 20 minutes. These are slow desolve and take effect after 30 minutes or so. My only issue was consistency. I would say that 90% of the time I would be drowsy. Once or twice a month they would have a minimal effect. They are a stronger dose, 5 mg versus 3 mg of the other product. They are less expensive and they work most of the time.
