At DMG Motorsports, we present the Spectro V-Twin Full Oil Service Kit EVO — a complete, all-in-one maintenance solution built specifically for Evolution-era big twin and Sportster V-Twin motorcycles. Instead of hunting down individual bottles of engine oil, primary chaincase lubricant, gear oil, a filter, and drain plug seals separately, this kit bundles everything you need into a single box so you can knock out a full-service oil change in one trip to the garage. Formulated with Spectro's trusted Premium Heavy Duty petroleum-based lubricants, this kit is designed to protect your engine, primary chaincase, and transmission with the correct viscosity oils for each component, helping maintain smooth shifting, reduced friction, and reliable protection under the demanding heat and load conditions typical of air-cooled V-Twin engines. Whether you're a shop tech or a DIY rider, this kit takes the guesswork out of sourcing the right oils and takes care of a complete service in one convenient package.

Features:

• 4 quarts of Spectro Premium Heavy Duty SAE 20W50 engine oil for reliable lubrication and wear protection in Evolution V-Twin engines
• 1 quart of Spectro Heavy Duty Primary Chaincase Oil to keep the primary drive and wet clutch running smoothly
• 1 quart of Spectro Heavy Duty Gear Guard GL-5 SAE 85W140 gear oil for the transmission
• Black oil filter included for complete engine oil filtration
• 3 drain plug O-rings included for a clean, leak-free reseal on every drain point
• Complete full-service kit that covers engine, primary, and transmission oil changes in one convenient package
• Designed for use on Evolution-era Harley-Davidson Big Twin and Sportster V-Twin motorcycles
