PJ1 New Improved Black Label Heavy Duty Chain Lube applies easily and features a foaming action that penetrates into the pins and rollers to set up into a tacky, grease-like coating. After penetrating the inside of the chain, the lube becomes a sticky lubricant that bounces back or has a “memory” effect that withstands the continual mechanical stress of the chain. Specially optimized for a standard non-O-ring chains, yet is O-Ring safe and compatible with either type of motorcycle chain. New super tacky formulation reduces dirty fly-off, displaces and repels water, protects against rust and corrosion, extending sprocket and chain life. Petroleum based, race proven, and environmentally friendly with minimal rolling resistance.
