The two bikes share the same motor platform, battery system and frame. The main difference is the wheel and tyre package, which changes where each bike works best.

RFN Warrior SX-E700 MX

The RFN Warrior SX-E700 MX is designed for traditional off-road riding. It uses off-road tyres that provide grip on mud, grass, loose dirt and rough terrain.

If your child rides fields, woodland tracks, motocross practice areas or private land, the MX version is the obvious choice.

MX Advantages

  • Maximum off-road grip
  • Better on grass, mud and loose ground
  • More confidence on uneven surfaces
  • True motocross-style feel
  • Most versatile for typical UK riding conditions

Best for: fields, tracks, private land, woodland riding and mixed terrain.

RFN Warrior SX-E700 SM

The RFN Warrior SX-E700 SM uses a road-biased wheel and tyre setup designed for smoother, harder surfaces.

The smoother tyre profile improves grip on tarmac and hard-packed circuits, making the SM version better for kart tracks, yard riding, driveways and supermoto-style use.

SM Advantages

  • More grip on tarmac
  • Sharper steering on smooth surfaces
  • Ideal for kart tracks and hard-pack circuits
  • Reduced tyre wear on hard surfaces
  • Supermoto-style look and feel

Best for: tarmac, kart tracks, driveways, yards and hard-packed surfaces.

Which One Is Faster?

Neither bike is meaningfully faster than the other.

Both versions use the same 500W brushless motor, 700W peak output, controller and 36V 7.4Ah battery platform. The top speed is broadly the same, so speed should not be the reason you choose one over the other.

Which One Handles Better?

That depends entirely on the surface.

Surface Best Choice
Grass SX-E700 MX
Mud SX-E700 MX
Loose dirt SX-E700 MX
Motocross-style riding SX-E700 MX
Tarmac SX-E700 SM
Kart tracks SX-E700 SM
Hard-packed circuits SX-E700 SM

The wrong tyre choice will make a much bigger difference than any performance specification.

Which Version Should Most UK Buyers Choose?

For most UK families, the SX-E700 MX is the safer and more versatile purchase.

Most young riders spend their time riding fields, gardens, private land, motocross practice tracks or mixed terrain. The MX tyre setup handles these conditions better and still works acceptably on hard surfaces when needed.

Choose The SX-E700 MX If...

  • Your child rides off-road.
  • You ride fields, grass, dirt or woodland.
  • You occasionally visit MX tracks or practice areas.
  • You want the most versatile setup.
  • You are unsure which version to buy.

Choose The SX-E700 SM If...

  • Your child rides mainly on tarmac.
  • You regularly visit kart tracks.
  • You want a supermoto look and feel.
  • You rarely ride on mud, grass or loose ground.

Final Verdict

The RFN Warrior SX-E700 MX and SX-E700 SM are mechanically very similar bikes. The decision comes down almost entirely to tyres and intended use.

For the vast majority of riders, the SX-E700 MX is the better option because it handles the widest range of riding conditions and suits typical UK off-road use.

The SX-E700 SM only becomes the better choice if most riding takes place on tarmac, hard-packed circuits or kart-track style surfaces.

Winner
