Summary: Maximum safety for big skills

The Radiator AF Crown Protection in 220 mm is the indispensable ally of winding tracks or categories requiring a large number of teeth. Wider than the standard model, it is specially designed to wrap the crowns from 76 to 85 teeth.

Machined in high quality aluminum, it acts as a real shield between your transmission and external aggression (prominent vibrators, debris, track outputs). Its robustness avoids that the crown does not go to the slightest impact, thus saving expensive chain breaks.

- Why choose 220 mm protection?

1. Adapted to the major reports: The diameter of 220 mm ensures that the protection slightly protrudes from the crown (76-85 teeth), touching the soil before the ring of the crown.

2. Aluminum Quality Aviation: Offers exceptional impact resistance while remaining light enough not to penalize the inertia of the back tree.

3. Anti-derailment: By framing the crown, it limits the side movements of the chain during the heavy twists of the chassis.

4. Durability AF Radiator: An irreproachable finish for an accessory that lasts several seasons.

💡 Michel's trick

"Skip to a 80-tooth crown without protecting in 220 mm, it's like rolling without headphones: it's risky! My Pro Council: Watch the wear of the disc edge. The trick: If you see that aluminum is very marked below, it's because it did its job and saved your channel. Warning: With a 220 mm disk, your ground clearance is reduced. Make sure your chassis is not set too low at the back, otherwise you are going to pivot 'on the disc in the bumpy turns, which can make you lose motricity. "

❓ FAQ SEO (Frequently Asked Questions)

Q: Can I use a 220 mm protection with a small crown of 65 teeth? A: Yes, it's technically possible, but you will unnecessarily lose the ground clearance. It is better to match the diameter of the disc at the waist of the crown.

Q: Are the fixing screws provided? A: Generally, the protection is fixed with the hardware already present on your crown holder. If your screws are too short, we offer elongated hardware kits.
