FAQs
Is the CST CM731 street legal?
Yes, the CST CM731 features an E-Mark certification, indicating it meets European standards for road use. However, its aggressive off-road tread may not provide the optimal street riding experience.
What is the difference between this tyre and a street tyre?
This tyre has an aggressive tread pattern designed for maximum grip in loose conditions like dirt, mud, and gravel. Street tyres typically have shallower, more continuous tread patterns for better contact and wear on pavement.
How do I find the correct tire pressure?
Refer to your motorcycle's owner's manual for the manufacturer's recommended tire pressures for front and rear tires. This information is often also found on a sticker on the motorcycle's frame, swingarm, or fuel tank.
How often should I check my tire pressure?
It's recommended to check tire pressure at least once a week, and always before a long ride. Pressure can fluctuate with temperature changes.
What does FIM Enduro mean?
FIM stands for the International Federation of Motorcycling. FIM Enduro certification means the tyre meets specific standards set by the FIM for competitive off-road Enduro racing.
Can I use this tyre on my sportbike?
This tyre is designed for off-road and enduro motorcycles. It is generally not suitable for sportbikes, which require tyres designed for high-speed pavement performance and cornering.
Troubleshooting
Tyre feels unstable or lacks grip on pavement
This tyre is optimized for off-road use. Check that tire pressures are set correctly for mixed-terrain riding. For primarily street use, consider a different tyre model.
Excessive vibration or imbalance
Ensure the tyre was professionally mounted and balanced. Re-balancing may be necessary. Check for any damage or foreign objects on the tyre or rim.
Rapid tread wear on street use
This is expected with aggressive off-road tread patterns used predominantly on asphalt. Reduce highway mileage or consider a dual-purpose tyre if street riding is the majority use case.
Difficulty mounting the tyre
Ensure correct tyre size and rim compatibility. Use appropriate tire levers and lubricant. If problems persist, consult a professional motorcycle technician.
