JIAXIMAN 3.5L Dirt Bike Gas Tank for 50–125cc Pit Bikes — Black Cap, CNC Aluminum Gas Cap & Complete Fuel Kit

JIAXIMAN's 3.5L replacement gas tank kit for 50–125cc pit bikes is a complete, durable fuel system upgrade that includes a CNC aluminum cap, petcock, fuel filter and hoses for reliable fueling on trail and track.

This replacement tank is designed to fit a wide range of small-displacement dirt bikes—Honda CRF50/XR50, KAYO TS90, Pitster Pro XJR110, SSR models and many Chinese pit bikes—offering stronger construction, improved sealing, and a ready-to-install parts kit. It comes pre-drilled for common mounts and includes components to control fuel flow and venting, minimizing leaks and pressure issues riders face with older or damaged tanks.

Will this tank fit my bike model?

The JIAXIMAN 3.5L tank supports many 50cc–125cc pit bikes but may need minor adjustments for some frame or year-specific CRF50 variants. Review your bike's mounting points and tank dimensions before ordering to confirm compatibility.

• Common fits: Honda CRF50/XR50, KAYO TS90, Pitster Pro XJR110, SSR50/70/110/125
• Also compatible with many Chinese mini dirt bike brands (Taotao, Coolster, Lifan, etc.)
• Small trimming or bracket adaptation may be required for exact fit
• Check measurements against your current tank pre-purchase

How does the CNC aluminum cap improve fuel sealing?

The CNC aluminum gas cap replaces fragile plastic caps and provides a tighter seal to reduce leaks, while the included vent tube balances internal pressure. This metal cap is more resistant to cracking and wear from vibration and fuel exposure.

• CNC-machined for accurate threading and a secure fit
• Robust against impacts and fuel corrosion compared with plastic caps
• Vent tube prevents vacuum or overpressure inside the tank
• Combined with proper clamps, reduces chance of spills during rides

What installation parts are included and how do they help?

The kit is delivered ready to install with a petcock, fuel filter, fuel hoses, clamps and a breath tube—everything needed to control fuel delivery and keep contaminants out of the carburetor. That saves you the hassle of sourcing separate hardware and ensures components match the tank's ports.

• 1 x petcock for straightforward on/off fuel control
• 1 x in-line fuel filter to block debris and protect carburetor jets
• 2 x fuel hoses plus 4 x clamps for secure hose connections
• Breath/vent tube to equalize tank pressure for consistent flow

Is the tank durable enough for off-road use?

The tank is molded from impact-resistant plastic engineered for small dirt bikes, while the metal cap adds durability where stress and vibration are greatest. Together they create a fuel system component designed to withstand typical trail and park conditions without frequent replacement.

• Thick plastic construction resists cracking from impacts
• Aluminum cap reduces fuel leakage and cap failures
• Quality hoses and clamps minimize disconnections under vibration
• Proper venting lowers internal stress during temperature changes

Who is this for: The JIAXIMAN 3.5L gas tank kit is aimed at pit bike owners, youth motocross riders, hobbyists restoring or upgrading 50cc–125cc dirt bikes, and mechanics who need a reliable, complete replacement tank. If you want a stronger cap, included fuel management parts, and broad compatibility with Honda small bikes and many Chinese models, this kit provides a straightforward, cost-effective solution.
