Full details

The CST CM-A4II Ride Ambro (150/70R18) is an ideal choice for dual-sport motorcycle riders who frequently transition between pavement and dirt paths. Its standout feature is the clever hybrid tread design that maintains high-speed composure on asphalt without sacrificing the bite needed for loose surfaces, though riders should note that dedicated off-road enthusiasts may find its performance limited in deep mud compared to specialized knobby alternatives.

FAQs

Is the CST CM-A4II suitable for highway touring?

Yes, the optimized density radial steel belt is specifically designed to provide high-speed stability, making it well-suited for long-distance highway travel.

Does this tire perform well in the rain?

The tire features a nano-silica compound that is specifically engineered to improve wet grip and surface adhesion.

Can I use this tire for motocross racing?

No, this is a dual-sport tire. It is designed for mixed road and light trail use, not for professional motocross tracks or heavy mud.

What is the primary advantage of the nano-silica compound?

It serves a dual purpose: improving traction on wet surfaces and extending the total mileage you get out of the tread.

How often should I check my tire pressure?

It is recommended to check your tire pressure at least once a week or before any long-distance ride to ensure safety and performance.

Troubleshooting

Bike feels unstable at high speeds

Verify that tire pressure matches your motorcycle manufacturer's specifications and ensure the wheels are properly balanced.

Rapid or uneven tread wear

Check wheel alignment and suspension settings, as these can significantly impact how dual-sport tires wear on mixed surfaces.

Setup, Compatibility & Care

Ensure your motorcycle wheel rim is compatible with the 150/70R18 specification before installation. Proper mounting by a certified technician is recommended to prevent damage to the steel belt structure. To maximize the life of your CST CM-A4II, perform the following care steps:

  1. Maintain correct tire pressure according to your motorcycle owner's manual for mixed-terrain use.
  2. Inspect the tread grooves periodically for lodged rocks or debris after off-road sessions.
  3. Regularly check the sidewalls for any signs of cracking or unusual wear patterns.
  4. Balance the wheels after mounting to ensure the stability provided by the steel belt remains effective.
