Suzuki Recalls Motorcycles for Faulty Master Cylinder

BREA, Calif. — Suzuki Motor USA, LLC has agreed to recall certain model-year 2022 Suzuki GSX1300RRQ/ZM2 (Hayabusa) motorcycles to correct a potential front brake master cylinder issue.

The 2,552 Suzuki motorcycles within the recall population were equipped with a front brake master cylinder

that was manufactured with an incorrect brake fluid primary port location.

This condition could lead to excessive front-brake lever travel during the first application of the brakes, a situation which could lead to longer stopping distances in the worst-possible situation.

According to the National Highway Traffic Safety Administration (NHTSA) Part 573 Safety Recall Report 23V-088 the cause of this potential problem is, “An improper location of the front brake master cylinder primary port may become blocked if swelling of the primary seal cup in an adjacent location occurs. In this case, fluid pressure change caused from normal cooling of the brake fluid of the vehicle could create a negative pressure condition in the brake system. If this occurs, the front brake caliper pistons could retract

creating excessive gap between the front brake pad and discs. In this condition, at the next application of the front brake the front brake lever will have excessive travel as the front brake pads move to contact the front brake discs and before brake system friction begins.”

The safety risk occurs under the worst-case scenario when braking distances are extended which could lead to a crash, according to NHTSA.

Further, according to NHTSA, the remedy includes replacement off the front-brake master cylinder body “with a new part that includes a repositioned primary port. The new part is identifiable by a punch mark on the master cylinder body imprinted on the handlebar clamp attachment face.”

Dealers were scheduled to receive notification of the recall by Feb. 27th; owners are scheduled to be notified by March 1st.
