Product Information
Full details
The CST CM712 Legion Trials Rear Motorcycle Tyre is engineered for off-road riders and trials enthusiasts who require maximum grip across technical terrain. By utilizing an ultra-soft rubber compound and a specialized tread design, it provides exceptional traction on challenging surfaces like wet rocks, loose dirt, and slick roots. While its design offers unparalleled performance in off-road competition, the soft compound nature means it is not intended for extended use on paved roads where high wear rates may occur.

FAQs
Is this tyre suitable for street use?
No, the CST CM712 is designed for off-road trials use. Its soft compound will wear down very quickly if used on paved roads.
Does this tyre require an inner tube?
This is a tubeless tyre, designed to offer improved performance and weight reduction, but it can be used with a tube if the rim setup requires it.
What is the primary benefit of the radial construction?
The radial construction creates a more flexible, wider footprint, which allows the tyre to conform better to obstacles for superior traction.
What terrain is this tyre best for?
It excels on technical, off-road terrain including loose dirt, slippery rocks, tree roots, and gravel.
How do I ensure the best traction?
Run the tyre at appropriate off-road pressures that allow the sidewalls to flex and the tread to conform to the terrain.
Troubleshooting
Difficulty maintaining tyre pressure
Check the bead seat for debris and ensure the rim is compatible with tubeless installation. If using a tube, inspect for pinch flats.
Tyre feels unstable on hard-packed trails
Verify that your tyre pressure is not too low; adjust pressure slightly upward to better support the carcass on high-speed sections.
Rapid tread wear noticed
Reduce riding time on abrasive, hard-packed or paved surfaces, as the ultra-soft compound is optimized specifically for technical off-road terrain.
Pros and Cons
Pros

- Flexible radial construction conforms well to obstacles
- Excellent for low-speed trials navigation
Cons
- Not optimized for high-speed street riding
- Softer compound may wear faster on abrasive surfaces
- Tubeless setup requires compatible rim configuration
Setup, Compatibility & Care
The CST CM712 4.00R18 is specifically designed for 18-inch motorcycle rear wheels. When installing, ensure the rim is compatible with tubeless applications to maintain the integrity of the tyre-to-rim seal. If your current setup uses an inner tube, verify compatibility with your wheel type, though this model is optimized for tubeless performance.
To ensure the longevity of the ultra-soft compound, inspect the tyre after every ride for embedded debris or tears. Store the motorcycle in a cool, dry place away from direct sunlight to prevent the rubber compound from drying out or prematurely hardening. Always monitor tyre pressure, as trials riding often requires running lower pressures to achieve the desired footprint, but ensure it remains within the manufacturer's recommended safe operating range.
