The newest member of the BATTLECROSS X series is here!  The BATTLECROSS X31 is for a broader range of intermediate terrain in big bike sizes.*  Starting where the X30 left off, the X31 is enhanced with Bunker Groove™ technology which results in greater traction in both harder and softer terrains.* Bunker Groove™ works by improving casing flex which enhances traction in harder terrain and adds biting edges for traction in softer conditions.*  Cooling Fins™ keep the feel consistent throughout your moto.

Benefits: 

  • True intermediate tire with improved traction in a broader range of terrain*
  • Rear tire Cooling Fins™ promote consistent traction and feel under continuous use (such as during a moto) by dispersing heat and minimizing inflation pressure gain. 
  • Bunker Groove™ technology – Two great benefits! 

1.  Increased casing flex in tread area improves lug contact for greater traction in harder terrain while helping to maintain sidewall stability.* 

2.  Provides additional biting edges when lugs are fully embedded in soft terrain.*

  • Symmetric front tire design enhanced with Castle Block™ promotes braking stability while increasing biting edges and contact pressure on soft and slippery surfaces.*
  • Asymmetric rear tire tread design featuring Castle Block™ enhances cornering traction by increasing lateral biting edges.*

Looking for a smaller intermediate terrain size?  Check out the Battlecross X30. 

*Comparison based on Battlecross X31 versus Battlecross X30 in internal testing.  Results may vary depending upon proper tire and vehicle maintenance, surface conditions, and riding habits.
