-Chessis: RedSpeed Rx R (BWD brake system)

The Redspeed Rx R is a high-end chassis from the factory production lines OTK Kart Parts. It shares the same geometry, the same tubes and the same components of high quality as its famous cousins (Tony Kart, Kosmic).

• Exception framework: Designed in 30 mm diameter chrome-molybdenum tubes, offering typical behavior OTK : Excellent motricity and a very incisive train.

• BWD braking system: Equipped with the high-end hydraulic system for categories without gearbox. It is characterized by a 180 mm rear brake disc ventilated and floating, offering excellent thermal dissipation and perfect constancy of the pedal touch.

• Magnesium accessories: Equipped as standard with magnesium components (rims, hubs, crown holder) to optimize the weight and behavior of the chassis.

- Engine: Rotax 125 Junior Max (National Category)

Engine Rotax Junior (Often called "national" in France according to the regulation of FFSA) is the reference engine for pilots from 12 to 16 years old.

• Adapted power: Develops about 23 horses, offering excellent performance / security report for high level learning.

• Legendary reliability: Equipped with centrifugal clutch, electric starter and liquid cooling. Its robust architecture makes it possible to roll a number of hours between each revision.

• Technical configuration: Comes with its carburettor dell'orto VHSB 34, its air box, its battery and its exhaust specific to the Junior category.

🔧 Adjustment and Maintenance Tips

1. Operation of the BWD brake: The 180 mm disc dissipates the heat very well. Use original pads OTK (usually thick 10 mm or according to specifications) to maintain progressivity to the pedal.

2. Rear grip: The stiffness of the 30 mm reddspeed frame fits perfectly with the torsion bars OTK. For the National category (often medium grip tires), start the tests without the rear bar to release the shift output chassis.

3. Maintenance of the exhaust valve: Note that the Junior (national) version does not use a mobile exhaust valve (unlike senior), which greatly simplifies the maintenance of the high engine.

💡 Michel's trick

"The Redspeed Rx R with the 180 mm BWD disc is a Swiss clock. The trick: In the national category, the secret lies in the speed of passage. My Pro Council: Do not on-use the large 180 mm disk by blocking the back; Take advantage of its progressivity to stabilize the kart in turn input without breaking the engine speed Rotax, who needs to keep rhythm to relaunch!
