The Ninja ZX-25R holds a unique spot in the 250cc class: it's the only production sportbike of this displacement with an inline four-cylinder engine (every competitor runs a single or twin). That's the source of its distinctive high-revving sound and its appetite for being kept spinning. View the Kawasaki Ninja ZX-25R in our catalog.

What owners say: the sheer novelty of a four-cylinder engine in the 250cc class is such a big deal that Kawasaki once released a dedicated video of this engine's sound on a dyno — commenters described the note as "angry" and "unhinged" for such a small displacement. Some experienced riders note that the factory quick shifter (with automatic downshift blipping) works brilliantly and turns ordinary Bali-speed riding into genuinely fun riding — you don't need track speeds to enjoy the shifts. On the downside: riders over 180cm report their legs start to tire from the riding position by the end of the day, and the suspension is tuned for the street, not the track. Peak power only arrives at 15,500 rpm, so anyone used to riding at low revs will find the bike feels flat until you rev it out.
Who it's for: confident riders who want maximum thrills out of the 250cc class and don't mind keeping the revs up — this isn't a bike for relaxed, low-rev cruising.
Where it shines on Bali: it's aimed more at the experience and character than any specific route — great in the same places as the MT-25 (town, the beach road), and on the world-class Mandalika circuit on neighboring Lombok. Not every rental company allows that kind of trip, but with us it's possible. This is the most demanding bike in the fleet — not for a first-ever motorcycle experience, and not ideal for tall riders on an all-day ride.
