Motorcycle, Scooter and ATV Lubricants

Motorcycle Lubricants & Support Products

From daily commuting and weekend touring to circuit racing, motocross and trials, Rock Oil supplies lubricants and maintenance products for motorcycles, scooters and ATVs. More than forty years of involvement in motorcycle competition informs a range built around engine protection, dependable clutch performance and complete machine care.

Engine oils for road, race and off-road riding

Many motorcycles share one lubricant between the engine, gearbox and wet clutch. Rock Oil offers synthetic, semi-synthetic and mineral oils to match different engines, riding conditions and manufacturer requirements.

SYNTHESIS: advanced synthetic performance

The SYNTHESIS Motorcycle range uses Tri-Synthetic technology combining ester, PAO and advanced base oils. Developed for high-performance four-stroke motorcycles, it supports engine cleanliness, wear protection and stable lubrication through demanding use. The brochure lists API SP and JASO MA2 performance across the range.

SYNTHESIS Motorcycle: a choice of viscosity grades for suitable modern road motorcycles with shared engine, gearbox and wet-clutch systems.
SYNTHESIS XRP 5W-30 and SYNTHESIS 4 RACING 15W-50: race-developed synthetic oils for applications requiring these grades.
SYNTHESIS XRP OFF-ROAD: synthetic 10W-40, 10W-50 and 10W-60 options developed for demanding off-road four-stroke use.

Everyday protection and specialist applications

GUARDIAN Motorcycle semi-synthetic oils use Ester-Guard technology for wear protection, deposit control and cold-start lubrication. GUARDIAN Motorcycle OFF-ROAD 10W-40 serves suitable off-road four-stroke engines, while GAMMA mineral oils provide traditional formulations for appropriate road and classic applications.

TRM 20W-60 offers a specialist racing option for suitable four-stroke engines, including roller-bearing and V-type designs. Select the viscosity and performance specification around the particular machine and its use.

Dedicated products for different machines

Two-stroke road and competition oils

Match the oil to the engine’s injector or premix system and its intended use.

SYNTHESIS 2 RACING: synthetic oil for premix-only racing applications.
SYNTHESIS 2 INJECTOR: synthetic lubrication for injector systems, with premix use where appropriate.
PP2: low-ash, semi-synthetic oil for injector and premix applications.

Follow the engine manufacturer’s instructions for product choice and mixing ratio.

Off-road motorcycles and ATVs

Dust, mud and intensive riding call for engine oils and support products matched to the machine.

CITY: scooter lubrication

Stop-start commuting and sustained road use put different demands on scooter engines. The CITY range offers dedicated four-stroke and low-smoke two-stroke products.

CITY 4 PLUS: synthetic four-stroke scooter oils, with the grade and performance requirements selected for the particular engine.
CITY 4 10W-40: semi-synthetic four-stroke scooter oil with JASO MB performance.
CITY 2 PLUS and CITY 2: synthetic and semi-synthetic two-stroke options for suitable injector and premix systems.

Check the specified viscosity and clutch requirements when choosing a scooter oil. JASO MA/MA2 and MB products serve different applications; our lubricant selector and technical team can help with selection.

Complete motorcycle care beyond the engine

Gearbox and suspension fluids

For machines with a separate transmission lubricant, options include SYNTHESIS XRP GEARBOX OIL, GEAR PRO 75W for suitable trials applications, GRO RACING GEAR OIL and semi-synthetic LITE GEAR OIL.

SYNTHESIS SVI synthetic racing suspension fluids and the semi-synthetic SVI Suspension Fluid series provide a choice of viscosities for damping control and suspension set-up. Select the fluid around the fork or shock manufacturer’s requirements.

Brake fluid and cooling systems

DOT 4 RACING BRAKE FLUID is developed for performance braking systems exposed to high temperatures where DOT 4 fluid is specified.

Ready-to-use coolant options include ICED KOOL with OAT inhibitor technology, KOOL-GUARD MEG -38 using IAT technology and KOOL-GUARD XL -38 using OAT technology. Match the coolant to the manufacturer’s requirements and, for competition use, the event rules.

Air-filter cleaning and protection

FACTORY FOAM AIR FILTER OIL provides a water-resistant treatment for foam filters exposed to dust and wet conditions. FACTORY ECO FOAM offers a water-soluble alternative that washes out with water.

FACTORY FOAM KLEEN helps remove oil and dirt before re-oiling appropriate filters, supporting regular maintenance for off-road bikes and ATVs.

Chain care and workshop maintenance

CHAIN LUBE penetrates chain components before forming a protective, low-fling film, while CHAIN WAX leaves a wax-based lubricating layer. CHAIN KLEEN supports cleaning before lubrication.

The maintenance range includes BRAKE KLEEN, CARB KLEEN, KONTACT KLEEN, ROCKEZE and SOC, alongside biodegradable DIRT BLASTER, NON-SILICONE BIKE WAX and SILICONE BIKE SHINE for suitable cleaning and finishing applications.
