Titanium caliper piston. Titanium Nitride coated. Part: 45107-MN5-006 >>Usually the rear piston<< Also part number:45107-GE2-006</> This part was made as a performance upgrade to the original steel part which corrodes and damages the seals causing the caliper to leak. These pistons have a Titanium Nitride (TiN) coating which is harder than the metal beneath and will also reduce friction with the caliper seals. The coating also gives a beautiful gold colour. It’s a shame it’s hidden within the caliper Titanium has an excellent property in that it’s a poor conductor of heat, so it’ll keep heat away from the brake fluid As you can see from the photos the Titanium piston is 20gm lighter than the original part The OEM part is £33.30 to buy from a major dealer, so this Titanium upgrade is a bargain! This part does NOT come with seals THESE PISTONS ARE NOT POLISHED >Yes the pistons are grade 5 Titanium, then coated with TiN coating<< I’m guessing everyone expects a catch these days >>If you’re unsure about the size measure the diameters of the pistons before buying and send me the dimensions stating the Bike model, year of manufacture and engine size of your bike and I’ll check on microfiche. It’s not worth buying in blind hope because in that case it definitely wont fit!<<
