• Cut, never stamped. Laser cut from virgin high carbon 420 stainless, then double disc parallel ground so both faces run true to each other.
• Thicker than the Bonneville disc at 5.0mm, on a smaller 220mm diameter. Triumph specified more material in less space on these bikes, and Galfer matches it rather than approximating.
• Heat treated for this application, not to one catalogue-wide spec.
• The wave shape is doing a job. More leading edge for the pad to bite on each rotation, and a shorter route for heat, water and pad dust to leave the surface.
• Direct replacement. Stock mounting points, stock caliper, stock pads. No bracket, no spacer, no modification.
• KBA ABE 61147 and TÜV approved. The German type approval number for Galfer's fixed Wave discs.
• Made in Granollers, outside Barcelona, in Galfer's own 6,000 square metre factory. They have been making friction materials there since 1952.

• One Galfer Rear Wave Rotor, DF907W
• Rotor bolts are not included. Triumph rear rotor bolts are single use on most applications, so plan on a fresh set

Difficulty: Straightforward. Comfortable for a home mechanic with a stand and a torque wrench. Time: About 45 minutes. Tools: Socket set, Torx or Allen depending on model, torque wrench, thread locker, brake cleaner.

1. Get the rear wheel off the ground on a paddock stand.
2. Remove the rear wheel following the procedure in your manual. Slacken the chain adjusters and drop the axle.
3. Unbolt the old rotor. If the bolts fight you, use heat rather than force. They are thread locked from the factory.
4. Clean the hub face completely. Anything left on it holds the new rotor out of true, and a rotor sitting out of true feels exactly like a warped one.
5. Fit the new rotor with fresh bolts and thread locker, tightening in a star pattern to the torque figure in your Triumph manual.
6. Refit the wheel, set your chain tension, and torque the axle to spec.
7. Wipe the rotor down with brake cleaner before you ride. Fingerprints and packing oil glaze a new surface.
8. Bed it in. Ten to fifteen progressively harder stops from moderate speed without coming to a complete stop, then let it cool fully before riding normally.

• This is the 1200 rotor, not the Bonneville one. The most common ordering mistake on these bikes. Check the selector.
• New pads at the same time. A used pad has worn to the shape of the old rotor.
• Budget for rotor bolts. Not included, and single use on most applications.
• You need a torque wrench. Rotor bolts go to a spec and get thread locked. Tightening by feel is how a new rotor ends up sitting out of true, and it will feel exactly like the warped one you just replaced.
• Bed it in properly. A rotor that is not bedded in feels worse than the one you took off.
• Sold individually. Your bike takes one.
