TITANIUM caliper piston part: 45218-MAJ-G41 (27 x 35)


TITANIUM caliper piston part: 45218-MAJ-G41

TITANIUM caliper piston part: 43107-MA3-006

27mm wide x 35mm long

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

Dimensions are 27mm wide x 35mm deep

CB600F (1998-99)
CR125 rear caliper 1987-2001
MX125 GROM rear caliper

The OEM part is £33.30 to buy from a major dealer, so this Titanium upgrade is a bargain!
