IMS Products 4.9 Gallon Fuel Tank for the Suzuki DR650

The Suzuki DR650 is an absolute dual-sport workhorse, but its factory 3.4-gallon steel fuel tank often limits how far off the grid you can confidently travel. The IMS Products 4.9 Gallon (18.5 Liter) Fuel Tank is widely considered the "Goldilocks" setup for the DR650. It provides a significant range increase over stock, ensuring you can tackle long Backcountry Discovery Routes (BDRs) without the bulky, top-heavy handling penalty associated with massive expedition-sized tanks.

Manufactured in the USA from high-impact, cross-linked polyethylene, this tank replaces the heavy factory steel unit and is built to shrug off rock strikes and tip-overs that would otherwise leave you with a dented tank. IMS specifically engineered the 4.9-gallon profile to keep the fuel weight low and maintain a narrow feel at the knees. This preserves the DR650's nimble handling on tight, technical singletrack. Additionally, unlike some larger oversized options on the market, the IMS design provides excellent clearance and typically does not require you to relocate your factory front turn signals.

Features:

• The "Goldilocks" Range: Increases fuel capacity to 4.9 gallons (18.5 liters), providing the ideal balance of extended backcountry range and agile handling.

• Slim Ergonomics: Expertly molded to retain a narrow profile between the rider's knees, ensuring it doesn't force your legs wide or interfere with an aggressive standing riding position.

• Cross-Linked Polyethylene: Manufactured from a proprietary high-impact plastic that flexes to absorb heavy trail abuse without permanently denting or cracking.

• Turn Signal Clearance: Engineered to provide sufficient clearance at full steering lock, allowing you to retain your factory front turn signals in their stock location.

• Complete Hardware: Comes ready to bolt on with a new screw-on gas cap, vent hose, fuel petcock, and all necessary mounting hardware.

Fitment:

• 1996–2026 – Suzuki DR650
  

Fitment Notes:

• Platform: Fits all Suzuki DR650S and DR650SE models from 1996 through 2026+.

• Seat Compatibility: Fully compatible with the OEM Suzuki seat and most aftermarket foam/cover kits (like Seat Concepts). Note: Because rigid fiberglass or carbon seat pans do not flex, this tank may not be compatible with certain Corbin seats without modification.

• Preventing Vapor Lock: It is critical to route the included gas cap vent hose properly. Many riders route it down into the steering stem hole. However you route it, ensure the hose is not pinched by your bar pad or tank bag straps. If that vent hose gets pinched or clogged with mud, the tank will vapor-lock, creating a vacuum that starves the carburetor of fuel and causes the bike to mysteriously stall on the trail.
