Vspec Parts & Accessories

Vspec lubricants come out of the Netherlands, formulated specifically for Harley V-twins — JASO MA and JASO MA/2 specs covering motors with combined engine, clutch, and transmission lubrication. SAE 50 for vintage Big Twins through to 20W50 and 10W40 modern formulations, plus transmission fluid, primary case oil, fork oil, and DOT 4 and DOT 5 brake fluid.

The complete service kits are the practical draw — exact quantities for specific Harley models, no guessing or buying twice. Engineered for the application rather than rebadged automotive oil, which matters more on these motors than most.
