CERMAX 4-Cycle Ceramic Synthetic Motorcycle Oil
All 4-Stroke Bikes — Cruisers, Sport, Touring, Adventure — Ceramic Protection at High RPM
CERMAX 4-Cycle is a nano Silicon Carbide ceramic synthetic motorcycle oil for all 4-stroke engines — cruisers, sport bikes, touring, and adventure bikes. Available at from $24.79/qt in a multi-viscosity formula that meets 4-stroke motorcycle specifications. Nano SiC ceramic bonds permanently to engine, transmission, and clutch-adjacent surfaces, providing high-RPM protection that standard motorcycle synthetic cannot match.

Why Motorcycles Need Dedicated Oil — Not Car Oil
This is one of the most important things every motorcycle owner needs to understand. Using car motor oil in a motorcycle — even a high-quality synthetic — can cause immediate and serious problems.
Car motor oils contain friction modifiers (ZDDP, molybdenum compounds) that reduce friction on all surfaces — including your clutch plates. In a wet-clutch motorcycle (where the clutch runs in the same oil as the engine), car oil causes clutch slipping, poor shifting, and eventual clutch failure. CERMAX 4-Cycle is specifically formulated without the friction modifiers that harm wet-clutch systems.
Beyond the clutch issue, motorcycle engines differ from car engines in two critical ways:
| Factor | Car Engine | 4-Stroke Motorcycle Engine |
|---|---|---|
| RPM range | Idle–6,000 RPM typical | Idle–15,000+ RPM — much higher shear stress on oil |
| Power per liter | 50–150 hp/liter typical | 100–200+ hp/liter — extreme thermal load per displacement |
| Oil system | Engine oil only | Often shared with gearbox and wet clutch — must be multi-compatible |
| Cooling | Mostly liquid-cooled | Air-cooled, oil-cooled, or liquid-cooled — oil carries more heat |
| Oil change frequency | 5,000–30,000 miles | Often 3,000–5,000 miles on standard oil — CERMAX extends this |
Which Bikes Use CERMAX 4-Cycle Oil
CERMAX 4-Cycle is suitable for all 4-stroke motorcycle engines. The multi-viscosity formula meets the broad range of viscosity specifications used across motorcycle manufacturers.
⚠️ Harley-Davidson owners: Many Harley models use separate oils for the engine, primary chaincase, and transmission. Verify your specific model's lubrication requirements before applying CERMAX 4-Cycle. Call us at 239-344-9861 for guidance on your specific Harley application.
How Ceramic Protects High-RPM Motorcycle Engines
At 10,000–15,000 RPM, motorcycle engine components experience stress levels that car engines rarely approach. Piston speeds, bearing loads, and oil shear rates are dramatically higher — and the consequences of oil film failure are faster and more severe.
🏁 The High-RPM Oil Challenge
At redline in a sport bike, the connecting rod and main bearings are rotating at speeds that create extreme centrifugal forces trying to push the oil film away from bearing surfaces. The oil film is at its thinnest at exactly the moment peak power is being transmitted. Standard motorcycle synthetic oil addresses this with high-viscosity-index base oils. CERMAX 4-Cycle adds nano SiC ceramic permanently bonded to bearing surfaces — providing dry-film protection that holds even when centrifugal forces thin the liquid oil film. This is the protection layer that matters most at 14,000 RPM.
| Condition | Standard Motorcycle Synthetic | CERMAX Ceramic 4-Cycle |
|---|---|---|
| Cold start (every ride) | Oil film must establish before RPMs rise | Ceramic layer already on surfaces — protection at first rev |
| High-RPM sustained (track, highway) | Film thins under centrifugal force at high RPM | Ceramic layer maintains contact zone protection |
| Air-cooled engines (high heat) | Oil carries more heat — degrades faster | Ceramic layer unaffected by heat — permanent protection |
| Wet clutch compatibility | No friction modifiers — clutch safe | No friction modifiers — fully wet-clutch compatible |
| Friction reduction | Standard motorcycle synthetic baseline | Up to 90% friction reduction* — smoother power delivery |
| Oil change interval | 3,000–5,000 miles typical | Extended interval with 30K Mile ceramic technology |
*Based on laboratory friction reduction testing. Individual results may vary.

Cerma STM-3 Motorcycle Engine Treatment
Pair CERMAX 4-Cycle oil with the Cerma STM-3 Motorcycle Engine Treatment for the full ceramic protection system. One application permanently bonds nano SiC ceramic to your motorcycle engine surfaces — providing protection that outlasts every oil change for the life of your bike.
🛡️ Cerma STM-3 Motorcycle Engine Treatment
One bottle. One application. Permanent nano SiC ceramic bonded to your engine. Apply at any oil change — pour into the engine and ride normally. The ceramic bonds over the first 1,000–2,000 miles.
One-time application · Compatible with all 4-cycle engines
Also available: Value Package (treatment + 2qt CERMAX oil) — $101.20
How to Use CERMAX 4-Cycle
| Item | CERMAX 4-Cycle |
|---|---|
| Application | Use at every oil change — replace your standard motorcycle oil with CERMAX 4-Cycle |
| Compatible bikes | All 4-stroke motorcycles — sport, cruiser, touring, adventure, standard, dual sport |
| Wet-clutch safe | Yes — no friction modifiers that harm wet-clutch systems |
| Ceramic bonding | Nano SiC begins bonding immediately; full protective layer over 500–1,500 miles (faster than car engines due to higher RPM cycling) |
| Air-cooled engines | Fully compatible — ceramic layer is unaffected by the higher oil temperatures in air-cooled applications |
| With motorcycle treatment | Apply STM-3 Motorcycle Treatment (1.25oz, $71.50) at the same oil change as CERMAX 4-Cycle for maximum ceramic protection |

Treatment
4-Cycle Oil
Apply the motorcycle treatment at the same time as your first CERMAX 4-Cycle oil fill. The treatment permanently bonds ceramic to your engine surfaces. CERMAX 4-Cycle then maintains and builds on that ceramic layer at every subsequent oil change. Or start with just the oil and add the treatment at your next change — both approaches work.
