SHIMANO Motorex Racing Fork Oil 4W - 1L pack (6 bottles), anti-foaming & thermally stable

Developed for suspension systems that demand consistent performance, this Motorex 4W fork oil balances viscosity and film strength so forks stay responsive whether the temperature drops or climbs. The 1L containers come with a maintenance pack for replacing gaskets and seals, and the product is sold in sets of six — priced individually — so workshops and serious riders can stock up efficiently.

How does this fork oil maintain consistent damping in different temperatures?

The 4-weight viscosity is formulated to provide a predictable flow characteristic from cold starts to sustained riding heat. Its base fluids and additives minimize viscosity drift, helping damping circuits respond similarly during short or long sessions.

• Stable 4W viscosity for predictable fork travel
• Low-temperature flow to reduce stiction on cold rides
• Thermally stable under prolonged use to avoid over-softening

Will it prevent foaming and protect internal components?

Yes — the additive package includes anti-foaming agents and corrosion inhibitors that reduce air entrainment and guard metal surfaces. That helps maintain consistent damping while extending the life of bushings and chrome-plated sliding parts.

• Anti-foaming agents to preserve damping feel
• Corrosion inhibitors to protect steel and aluminum internals
• Cleaner-running formulation that lowers sludge buildup

What is included in the maintenance pack and why is it useful?

Each 1L bottle includes a maintenance pack with replacement gaskets and seals sized for common fork services. Having fresh gaskets on hand ensures tight sealing during reassembly, reduces leaks, and shortens service turnaround times.

• Replacement gaskets and seals for fork service
• Saves time by bundling consumables with the oil
• Helps ensure a leak-free rebuild and correct oil level

How should workshops and riders buy this product?

Motorex Racing Fork Oil 4W is sold in sets of six 1L bottles, with pricing listed per individual unit — a practical option for shops or riders who perform frequent services. Ordering by the set reduces the need to restock frequently and keeps a consistent batch of oil on hand for multiple bikes.

• Sold as a set of 6 × 1L containers; priced each
• Good stock level for workshops and enthusiast mechanics
• Consistent lots reduce variance between services

Who is this for: Riders and technicians who demand reliable, repeatable fork performance across varied temperatures — including racers, enduro and trail riders, and service shops — will benefit from Motorex Racing Fork Oil 4W. It’s designed for regular maintenance and rebuilds where foaming resistance, corrosion protection, and included maintenance consumables matter.
