Engine & Drivetrain
The heart of your FWE is a high-output, precision-tuned power plant that demands frequent, high-precision maintenance to stay at the front of the pack.
- Engine Top End and Piston Kit: For FWE models from 2020 through 2026, the top end must be serviced every 20–30 hours to maintain the high compression required for consistent holeshot power. We stock high-velocity piston kits for 2024 FWE models and precision kits for 2021 FWE builds to keep your engine output at peak race performance throughout the entire season.
- Engine Clutch and Kick Lever: A slipping start is a lost race, and inconsistent clutch engagement can ruin a weekend. We maintain a daily stock of 5Gx clutch parts—including clutch shoes for 2022 FWE and washer stacks for 2025 FWE models—to keep your system performing flawlessly. Don't let a worn kick lever or a faded clutch assembly compromise your race-day performance when you need it most.
- Bottom End & Transmission: When it's time for a full rebuild, we supply the crankshafts and transmission gears for 2024 FWE and 2022 FWE transmissions to keep your engine running factory-smooth and vibration-free.
Cooling System: Radiators & Hoses
Effective heat management is vital for high-RPM race engines. If your FWE runs hot, you are losing valuable horsepower and risking catastrophic engine damage during long, grueling motos.
- Radiators and Radiator Hoses: We stock factory-spec radiators and high-pressure reinforced hoses for 2024 FWE models and 2021 FWE cooling kits to prevent performance drop-off. A cool-running engine is an efficient engine, and our kits ensure your bike maintains optimal operating temperatures from start to finish.
Carburetion & Intake
When your FWE feels "flat" coming off the gate or bogging during mid-turn acceleration, the intake system is almost always the culprit. Your engine needs consistent, clean airflow to generate maximum power.
- Carburetor and Intake Parts: From jet kits for 2025 FWE to reed cage assemblies for 2022 FWE, we stock the parts that keep all model years breathing perfectly. Maintaining a clean intake tract and the correct air-fuel ratio is the secret to extracting every ounce of power from your Cobra FWE engine.
Exhaust System
Your engine needs to exhale as efficiently as it inhales. A damaged pipe or clogged silencer can instantly kill your mid-range snap and top-end over-rev.
- Exhaust Pipes & Silencers: Refresh your 2024 FWE exhaust or 2022 FWE silencer parts to maintain optimal backpressure and flow, ensuring your bike delivers the crisp, authoritative sound and power that Cobra FWE owners expect.
Electrical System
A reliable electrical system is the lifeline of your race bike, ensuring that every time the gate drops, you have an immediate, consistent start and flawless ignition timing.
- Stator, Ignition Coil, and Spark Plugs: Ensure your race bike never loses spark or misses a beat. We stock ignition hardware, including stator assemblies for 2023 FWE and ignition coils for 2020 FWE models, for the reliable, consistent electrical output required for high-RPM racing.
Suspension: Forks & Shocks
Aggressive track conditions require a suspension setup that works with the rider, not against them. If your rider isn't confident in the corners, it's time to refresh these internal hardware.
- Forks and Triple Clamps: Maintain your front end with fork seals for 2025 FWE and triple clamp hardware for 2021 FWE models to keep the bike tracking true through ruts and bumps.
- Shock Assembly & Internals: Refresh your rear suspension with 2024 FWE shock kits and 2022 shock internals to handle the harsh terrain of national-level tracks, ensuring maximum traction.
Controls & Ergonomics
Precision control is what separates a podium finisher from the rest of the pack. Your inputs must be direct and seamless every time.
- Bars and Controls: Keep your inputs sharp and responsive with handlebars for 2022 FWE and throttle cables for 2025 FWE models. These are high-wear items that deserve a refresh to prevent sticky throttles or sloppy steering.
- Plastic Bodywork and Seat: Keep your bike looking factory fresh with plastic kits for 2024 FWE and seat covers for 2021 FWE bikes. A clean, sharp bike is a testament to the factory-level care you put into your racer.
Chassis & Braking
Aggressive racing demands elite stopping power and stable, predictable handling in every corner. You cannot push the limits if you aren't 100% confident in your braking system.
- Front Brakes & Rear Brakes: Our brake pads for 2023 FWE and calipers for 2025 FWE provide the consistent feel and extreme stopping power elite racers demand, whether you are pushing the limits on a 2021 or 2026 FWE.
- Rear Wheel & Drive Hardware: Stock wheel bearings for 2022 FWE and sprockets for 2024 FWE models to keep you driving hard out of corners. Efficient power transfer is the key to winning, and these parts ensure every bit of horsepower reaches the ground.
