Best for: Built primarily for spirited backroad riding and track days where precise cornering and light weight matter more than raw straight-line power.
Built for: A focused, lightweight sportbike with a lively parallel-twin engine, premium Ohlins suspension, and razor-sharp cornering manners.
Not ideal for: Not a good fit for riders wanting a relaxed upright commuter, long-distance tourer, or anyone needing genuine passenger comfort or luggage capacity.
