When charm meets power: the NRG50 12/10" Kids Dirtbike, a machine designed for future champions
The Powerful Kids Dirtbike NRG50 12/10" from Nitro Motors embodies the perfect blend of performance and safety for young riders. With its 50cc 2-stroke air-cooled engine delivering 6.6 kW and a top speed of 50 km/h, this mini motocross bike offers an exciting yet controlled riding experience, ideal for children aged 6 to 10. Its aggressive design, inspired by competition models, and its powerful sound thanks to the racing exhaust will thrill young riders while reassuring parents about its robustness. At XtremRS, we selected this model for its German reliability (imported by Menila GmbH) and its unmatched quality-price ratio in thermal kids' dirtbikes.
Kickstart: simplicity that enhances young riders' independence
Forget batteries to recharge or finicky electric starters! The NRG50 12/10" features a robust kickstarter, specially designed for small legs. This mechanical system offers several key advantages:
- Unmatched reliability: no electronic failures, even after years of intensive use.
- Technical learning: the child develops a sense of timing and coordination, essential skills for progressing to more powerful bikes.
- Enhanced safety: the kickstart prevents accidental starts (unlike an electric button).
XtremRS Tip: To make starting easier, teach your child to place the bike on a flat surface and use body weight rather than brute force. Regular maintenance of the kickstarter (lubricating the axles) extends its lifespan – check out our complete maintenance guide for 49cc engines.
Aluminum frame and chassis: a competition-grade structure for a premium kids' dirtbike
The heart of the NRG50 lies in its sprayed aluminum frame (anti-corrosion treatment) and a redesigned swingarm to absorb landing shocks. This premium architecture offers:
- Optimal rigidity: the featherweight of 39.8 kg (empty) is perfectly distributed for stability in turns.
- Exceptional durability: aluminum resists scratches and rust, even after muddy sessions.
- Adapted geometry: with a seat height of 61 cm and a wheelbase of 94 cm, the riding position is natural for children from 1m20 to 1m40 tall.
XtremRS Expertise: Unlike low-end steel models, this frame effortlessly supports the 60 kg maximum load (rider weight + gear). To check its condition, regularly inspect the weld points and engine mounts – our safety checklist guides you step by step.
Telescopic fork and rear shocks: the winning duo for optimal comfort and safety
The NRG50 12/10" stands out with its front telescopic fork (30 mm diameter) and hydraulic rear shock, rare features on a kids' dirtbike. This high-end suspension ensures:
- Superior shock absorption: ideal for rough terrain (bumps, roots) or jump landings.
- Trajectory control: the aggressive tread pattern of the 2.50x10" tires (front/rear) grips the ground to prevent skidding.
- Progressive adjustment: the rear shock allows preload adjustment based on the child's weight.
Terrain Recommendation: For tracks like La Roche-en-Brenil (Burgundy) or Venarey-les-Laumes, where elevation changes are frequent, this suspension makes all the difference. Maintenance Tip: Clean the fork seals after each ride to prevent premature wear (see our dedicated tutorial).
Racing exhaust: powerful sound and optimized performance for a 50cc kids' dirtbike
The NRG50's specific exhaust is more than just aesthetics: it's a key component for performance. Its advantages:
- Deep, motivating sound: the "kerniger Sound" (as described by the manufacturer) encourages the child without being deafening (complies with European noise standards).
- Torque gain: the exhaust geometry optimizes gas flow for more responsive acceleration.
- Unmatched durability: made of stainless steel, it resists heat and mud splashes.
Warning: To maintain performance, always use a 20:1 oil/gasoline mix (high-quality 2-stroke oil). A clogged exhaust reduces power and increases fuel consumption – our guide on thermal engine ignition explains how to diagnose related issues.

No, this model is strictly designed for one rider. The maximum authorized load is 60 kg (child's weight + gear). Riding with two would be:- Dangerous (imbalance, fall risk).- Illegal (even on private land).- Harmful to the frame and suspension (premature wear).For dual use, opt for a 125cc or larger dirtbike with a two-seater.
14. Where can I find spare parts for this model?
Spare parts (tires, chain, fairings, etc.) are available:1. On our website ("Parts & Accessories" section).Tip: Prefer original parts to ensure compatibility and safety.
