The M2R CRF70 KMX140MX

The KMX140 MX pit bike is the ideal bike for riders taking the next step up from a mid-sized dirt bike or riders aged 14 and up.

The CRF70 range of bikes are bigger than the equivalent CRF50 range by around 10cm, making them much more comfortable for adults and teens when riding “in the seat”.

The KMX140 MX is equipped with the latest CRF70 chassis and our engineers have fitted an oil cooled high performance YX Motorsport Race engine to match!

From field and gravel tracks to a full blown Moto X course, the KMX140 MX will perform splendidly. (For MX we recommend the excellent DNM Rear shock upgrade).

Special Features:

  • Kenda carlsbad tyres
  • New stronger wheels
  • Front and rear rim locks fitted as standard
  • Fully adjustable rear shock with 1000LB spring
  • High quality extended aluminium rear swinging arm

The M2R Limited Edition comes with carbon look plastics, gold alloy rims, gold forks, silver triple clamps, and Limited edition graphics kit.

The KMX140MX pit bike has a 4 speed manual gearbox with gears being a simple arrangement of neutral to fourth - (N -1-2-3-4) or 4 - up.

Even some of the world's best riders use our pit bikes!

All spares and upgrades are available from.

** This product requires assembly of Handlebars, Front wheel, Front mud guard, and rear suspension attaching before use. Please also give the bike a full inspection, change oil and check chain tension.
