Frequently Asked Questions

Is this rotor street legal?

Yes — Lyndall rotors are designed and tested for street and extreme riding conditions.

What's the warranty on this rotor?

Lyndall guarantees this rotor for the life of your bike when used exclusively with Lyndall premium quality organic brake pads.

Will this fit my 2018+ Softail?

2018-up Softails can use a 5mm rear rotor, but this is a 7mm rotor. Check fitment or consult Lyndall for the correct thickness for your model.

Do I need special brake pads with this rotor?

For the lifetime warranty to apply, use Lyndall premium quality organic brake pads. Other pads may work mechanically but will void the warranty.

Why is it called a lug-drive rotor?

The helical retaining ring uses a lug-drive system to secure the friction ring to the carrier center, preventing loosening and noise after extended service.
