Losi Promoto MX vs Promoto SM – Same Platform, Two Riding Styles

When Losi announced the Promoto series, few believed an RC motorcycle could actually feel real. Now, with the MX and SM models both out, that disbelief has turned into obsession — because these bikes don’t just look scale, they ride like it.

1. The Promoto Platform: A Revolution in RC Motorcycles

The Losi Promoto isn’t the first RC motorcycle ever made — but it’s the first one that truly works like a real bike. Both the MX and SM models share an identical electronic and mechanical foundation designed from the ground up to replicate full-size handling. At the heart of this platform lies Losi’s MS6X control system and a 2700Kv brushless motor spinning a precision-balanced flywheel at over 22,000 RPM. This gyroscopic force keeps the bike stable, allowing it to lean naturally into corners, pop wheelies, and recover from bumps with real-world grace.

Both versions also share a chain-driven drivetrain and a fully tunable suspension setup. The rear shock uses a rising-rate linkage geometry — a concept borrowed straight from full-size motocross bikes — while the front fork uses silicone dampening oil that can be adjusted for terrain type. The result is an RC motorcycle that feels planted, agile, and alive under throttle.

2. Promoto MX: Built for the Dirt

The Promoto MX was made for those who dream of kicking up dirt and carving berms. It comes equipped with knobby off-road tires, long-travel suspension, and protective bodywork designed to shrug off dust, roost, and minor tumbles. On a rough track or open field, the MX version feels every bit like a scaled-down motocross racer — balanced, grippy, and incredibly satisfying to slide through corners.

Many early owners describe it as the most fun RC release of the decade. One rider put it best: “It’s still just as fun six months later as the day I brought it home!” Another said, “It’s the best RC 2023 — hands down!” Those reviews sum up the appeal perfectly: it’s fast, dramatic, and endlessly addictive.

3. Promoto SM: Precision on the Pavement

While the MX tackles the dirt, the Promoto SM (Supermoto) is tuned for asphalt and smooth surfaces. It shares the same internal architecture but trades knobby tires for street slicks and recalibrated suspension for sharper turn-in and body control. The result? A bike that leans predictably and maintains stability even in long, sweeping corners — ideal for parking-lot racing or scaled-down street circuits.

The SM is all about rhythm and flow. Where the MX encourages wild wheelies and slides, the SM rewards smooth throttle control and racing lines. It’s not just a re-skin — it’s a refined driving style built on the same DNA.

4. Shared DNA: Same Power System, Same Battery

Despite their differences, both bikes are powered by the exact same electronics and battery system. That means any 2S LiPo battery compatible with the Promoto MX will drop directly into the Promoto SM, no mods needed. This shared design makes upgrades easy and universal across both versions.

For the best performance, we recommend switching to high-discharge CNHL packs designed for RC competition. These deliver consistent power for extended sessions and help the Promoto platform reach its full potential.

5. Real-World Impressions from the RC Community

Owners from around the world have praised the Promoto series for its engineering and realism. Comments like “It’s an animal if you keep it within its limits” and “The handling and suspension geometry feel like a real dirt bike” appear again and again. The only common critique? Battery life — which is exactly where CNHL packs step in, offering up to 30% longer runtime with higher voltage stability under load.

6. Recommended CNHL Battery Upgrades

Here are the top CNHL batteries tested and proven for the Promoto platform:

• CNHL Racing Series 5600mAh 7.4V 2S2P 120C Hard Case LiPo – Lightweight, high punch for aggressive riding.
• CNHL Racing Series LiHV 6000mAh 7.6V 2S 120C HV Hard Case LiPo – Higher voltage for faster throttle response and more torque.
• CNHL Racing Series 6600mAh 7.4V 2S2P 120C Hard Case LiPo – Maximum capacity for endurance riding sessions.

7. Conclusion: Two Styles, One Breakthrough

The Losi Promoto series is more than a pair of RC bikes — it’s a proof of concept that scaled realism can work. The MX version channels the spirit of off-road adrenaline, while the SM captures the precision of street racing. Whichever direction you lean, both share the same heartbeat — and both come alive with the right battery upgrade.
