#### **Cons**
1. **Limited On-Road Performance** The 660cc engine lacks the power needed for high-speed highway stability or aggressive on-road riding. It s not a bike you d want to cruise at 80 mph for long periods.
2. **Basic Suspension** The stock suspension is stiff and not optimized for heavy riders or extreme off-road conditions. Upgrades (e.g., hlins, Showa) are often necessary for serious trail use.
3. **Poor Fuel Tank Capacity** At **4.5 gallons**, range is limited compared to larger adventure bikes, requiring more frequent refueling on long trips.
4. **Outdated Technology** Being from 2004, it lacks modern features like **trail assist, advanced ABS, or electronic suspension adjustment**. Navigation and connectivity options are minimal.
5. **Tire Wear** The stock tires (e.g., **Yamaha MT-03 or similar**) are not ideal for both on-road and extreme off-road use. Upgrading to **knobby off-road tires** reduces on-road grip and increases wear.
6. **Rust and Maintenance Issues** Older bikes, especially those exposed to harsh conditions, may suffer from **frame rust, seized components, or worn belts**. A thorough inspection is crucial.
7. **Limited Aftermarket Support** While parts exist, some high-end aftermarket components (e.g., **custom fairings, advanced suspension**) are less developed compared to newer bikes.
8. **No Standard ABS** Without ABS, braking on slippery surfaces (e.g., mud, gravel) can be risky, especially for inexperienced riders.
9. **Discomfort on Long Rides** While the ergonomics are better than most dual-sports, the lack of wind protection and seat comfort can make long trips tiring.
10. **Depreciation** As a 20-year-old bike, it will continue to lose value over time, and parts may become harder to find as production ends.
