Control Window DRAG SPECIALTIES (manufacturer ref. 07-0540-S) — a small but vital component for keeping an eye on the hydraulic fluid of the master cylinder.

Ideal for vintage/classic enthusiasts, touring bikes or roadsters undergoing restoration or regular maintenance, this window allows you to quickly check the level and condition of the brake/clutch fluid without removing the reservoir.
The supplied rubber sight glass facilitates fitting and limits the risk of leaks when properly installed. To be replaced during a lever rebuild or when the sight glass shows scratches, cloudiness or signs of wear. Examples of compatible models: Harley-Davidson FXSTSB, FXSTS, FXSTC (1995 - 1340 cc).
A simple part, essential for maintaining a calm ride and a readable reservoir during your pre-ride checks.
