JRL Fuel Tank Cap Cover for Honda CRF/TRX 2005–2010 — CNC T6-6061 Aluminum, 60mm ID

JRL Fuel Tank Cap Cover is an aftermarket CNC T6-6061 aluminum replacement cap designed to fit Honda CRF 250R/250X/450X, TRX 450R and 400EX models from 2005–2010.

This lightweight, machined billet gas cap cover swaps in for worn or missing caps and adds a durable, scratch-resistant finish to your dirt bike. It comes with a short gas cap hose and a built-in respirator to reduce fuel seepage if the bike tips over. Before ordering, confirm the cap dimensions (60mm inner diameter, 65mm external diameter) match your existing tank opening because this is a non-original aftermarket part.

Will this fuel tank cap fit my Honda CRF or TRX model?

The JRL cap is built to match the common fuel neck dimensions used on Honda CRF 250R/250X, 450X, TRX 450R and 400EX models from 2005–2010. Measure your current cap opening to be sure: the inner diameter is 60mm and the external diameter 65mm. If your measurements match, the cap should install without modification.

How durable and protective is the JRL CNC aluminum cap?

Machined from T6-6061 CNC billet aluminum, the cap offers superior resistance to scratches and wear compared with standard plastic caps. The solid aluminum construction also helps protect the fuel neck from impacts and road debris. A built-in respirator helps vent pressure and reduces the chance of fuel leaking if the bike falls.

• Material: CNC billet T6-6061 aluminum for long-lasting durability
• Scratch and wear resistant finish
• Integrated respirator to help prevent fuel leakage on tip-over
• Sturdy fit to shield the fuel neck

What comes in the box and how is installation handled?

The package contains one tank cover and a short gas cap hose for tethering to the tank. Installation is typically straightforward: remove the old cap, confirm the dimensions, and secure the JRL cap in place. Use basic hand tools if required and follow common-sense safety precautions around fuel.

• Package includes: 1 tank cover with short gas cap hose
• Approximate weight: 122g — lightweight replacement
• No special parts required for standard-fit models
• Aftermarket item — not OEM, check fit before installation

Will switching to this aftermarket cap affect my bike’s performance or warranty?

Replacing a fuel cap with an aftermarket cover does not change engine performance; it provides a durable closure and venting. However, because this is a non-original part, confirm warranty or dealer concerns with your service provider before installing on a new or warranty-covered bike. The cap includes a respirator but does not alter fuel delivery systems.

• Performance: no change to fuel delivery or engine operation
• Warranty: aftermarket part — check with dealer if concerned
• Safety: designed to vent and reduce leakage risk on tip-over

Who is this for: Riders who own a compatible 2005–2010 Honda CRF or TRX model and want a tougher, longer-lasting fuel cap swap without changing fuel-system components. It’s ideal for off-road racers, trail riders and anyone replacing a damaged or missing OEM cap. Make sure the cap opening measures 60mm inside and 65mm outside before buying to ensure a correct fit.
