Best for: Designed as a sport tourer of its era, blending strong straight-line performance with reasonably capable handling for fast road riding and occasional longer trips.
Built for: Delivers a classic early-90s sport bike feel with a punchy inline-four engine, sharp throttle response at higher revs, and confidence-inspiring but not razor-sharp handling.
Not ideal for: Not a good fit for absolute beginners, off-road use, or riders seeking modern levels of comfort, wind protection, or long-distance touring ergonomics.
