Best for: Built as a lightweight, race-bred sport machine, it excels at high-rev canyon carving and trackday lapping rather than practical transport.
Built for: It rewards an aggressive, revvy riding style with explosive two-stroke acceleration once on the boil and razor-quick direction changes thanks to its very light dry weight.
Not ideal for: This is not the bike for riders wanting all-day comfort, passenger-friendly touring, or a forgiving, low-maintenance commuting experience.
