VFR400 TITANIUM front caliper piston set for one caliper

Top piston: 45117-MR7-006   30mm wide x 22mm deep
Bottom piston: 45118-KV3-701  25mm wide x 22mm deep

Total weight = 97gm per caliper

The castellated contact edge is to allow airflow into the piston cavity as well as reducing the contact area with the pad and reducing the amount of heat going into the piston and heating the brake fluid.

Half the weight of the original part.  These pistons reduce Unsprung weight, giving your suspension a quicker reaction time to bumps

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
