Brand new Genuine HONDA OEM front brake master cylinder assembly. This is the original part from Honda built by Nissin in Japan.

NOT a cheap made clone part. This is the real Nissin item.

Master cylinder comes as you see in the picture,..comes with the lever, lever pivot bolt, clamp half, and both clamp bolts. All are Honda factory parts and will be in Honda packaging.

Free shipping within the United States!

As always, if we have it listed on here, it is IN STOCK!!  We do not pre-sell items and order later or drop ship from elsewhere. Quantities shown available are live quantity numbers.

Master Cylinder Assembly is direct factory replacement for the following models...

1983-1987 ATC 200X

1981-1986 ATC 250R

1985-1986 ATC 350X

(PLEASE NOTE...Most 1981-1984 ATC 200X/250R models used a plastic body reservoir from Honda as original equipment,.. however, this 1985-up style master cylinder is a direct replacement upgrade for those models as well. For those models, keep in mind that YOU DO NOT USE THE MASTER CYLINDER GUARDS FROM PLASTIC RESERVOIR MASTER CYLINDERS ON METAL HOUSING MASTER CYLINDERS. Metal body master cylinders do not require them,..for obvious reasons,..but if you want to use them for cosmetic purposes they can be used on metal bodys by using your half clamp and bolts from the plastic version.)
