XtremRS Advice: To preserve performance, regularly check the spark plug and oil level, and follow our expert maintenance guide. Its oversized exhaust with a large collector improves not only the racing sound but also the evacuation of gases for optimal performance.
Up-Side Down Suspension and Hydraulic Shock Absorber: Comfort and Control in All Conditions
The NRG50 RS Racing stands out with its high-end suspension, rarely seen on a 50cc dirtbike. At the front, an absorbs shocks with surgical precision, while at the rear, a hydraulic shock absorber keeps the wheel on the ground even in the most technical jumps. This system offers:
- Increased stability in turns and straight lines, ideal for young riders in training.
- Optimal comfort on uneven terrain (bumps, roots, stones).
- Enhanced durability thanks to sealed joints and anti-corrosion materials.
XtremRS Recommendation: Adjust the rear spring preload based on the rider's weight (up to 75 kg of payload) for perfect behavior. For more information on suspension maintenance, consult our expert guide (principles also apply to thermal models).
Racing Fairing and Ultra-Resistant Frame: Design and Protection for a Premium Dirtbike
The aggressive design of the NRG50 RS Racing is not just a matter of aesthetics: its high-density injected plastic fairing protects vital components (engine, radiator, wiring) from mud projections and shocks. The aluminum fixings and reinforced welds of the frame guarantee unrivaled rigidity, even after hundreds of hours of practice. The details that make the difference:
- UV-resistant paint for a durable new look.
- 3D decals anti-flaking for a pro style.
- Enlarged wheel passage to mount wider tires if needed.
Safety Tip: After each session, clean the fairing with a microfiber cloth and soapy water to avoid the accumulation of abrasive mud. For adapted safety equipment for this model, consult our safety guide 6-10 years.
Reinforced Fork and Wide Handlebar: Precision and Maneuverability for a 12/10 Inch Dirtbike

2. Is this 50cc Dirtbike approved for road use in France?
No, this NRG50 RS Racing model is not approved for road use. It is designed exclusively for off-road use (private circuits, closed grounds, competitions). For legal use on public roads in France, a dirtbike must be equipped with lights, approved exhaust, and have a registration card. This model is sold without these equipments. However, we offer homologation kits as an option (to be verified according to current regulations).
3. What is the actual power of the engine (6.6 kW / 9 PS) and is it legal in 50cc?
The engine develops 6.6 kW (9 PS), which is higher than the European legal limit for a 50cc road-approved vehicle (4 kW / ~5.4 PS). However, since this dirtbike is not intended for road use, this power is allowed for competition or leisure use on a closed circuit. Note: In France, for minors, the maximum allowed power in competition is often limited to 5 PS (according to the feds). Check the rules of your club or circuit.
4. What type of transmission and starting system does this Dirtbike have?
This model is equipped with: - An automatic transmission (no manual clutch), ideal for beginners or riders wanting to focus on riding. - A kickstarter (starting pedal), typical of racing dirtbikes for more lightness and reliability in extreme conditions.
5. What are the advantages of the "Up-Side Down" suspension and the hydraulic braking system?
- Up-Side Down (USD) shock absorbers: These inverted suspensions offer better rigidity, more precise response to shocks, and a reduction in unsprung weight, improving handling on all terrain and stability at high speed. - 2-circuit hydraulic braking: Hydraulic disc brakes (front/rear) ensure progressive and powerful braking, even in muddy or dusty conditions, with reduced wear compared to mechanical systems.
6. What fuel/oil mixture should be used and what is the autonomy?
This 2-stroke engine runs on a 1:20 fuel/oil mixture (5% oil for 95% unleaded 95 or 98 gasoline). The tank has a capacity of 1.5 liters, which gives an autonomy of approximately 40-60 km depending on the driving style (shorter in competition, longer in gentle riding). We recommend using high-quality 2-stroke oil (e.g., Motul, Castrol) to preserve the engine.
7. Is this Dirtbike suitable for beginners?
Yes and no. For: - Automatic transmission (no clutch to manage). - Light weight (43 kg), easy to handle. - Progressive power thanks to the 2-stroke engine.
