Best for: Built for flickable fun on twisty roads, urban darting, and light supermoto-style thrashing rather than outright speed or distance.
Built for: A playful, lightweight single-cylinder machine that thrives on quick direction changes and eager, high-revving character over raw power.
Not ideal for: Not a good fit for riders wanting sustained highway comfort, long-distance touring capability, or serious two-up passenger use.
