How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a versatile adventure-tourer of its era, equally happy commuting, exploring gravel roads, or covering long distances at a modest pace.
- Built for
- A charming early-90s big-single adventure bike with a thumpy, torquey engine character rather than outright speed, valuing simplicity and rugged capability.
- Not ideal for
- Not the right choice for riders seeking high-speed highway cruising or track-level performance, as its modest power and top speed limit those pursuits.
