Kymco Xciting S 400
The Kymco Xciting S 400 has a top speed of 145 km/h, produces 35 hp and weighs 215 kg. Motoryk rates it 7.8/10.
The Kymco Xciting S 400 was introduced in 2018 as a significant update to the Xciting 400 lineup, featuring a redesigned chassis, updated styling, and improved ergonomics to compete in the premium maxi-scooter segment. It was notable for being one of the first scooters in its class to offer a standard TFT display, smartphone connectivity via Kymco's Noodoe system, and a refined 399cc single-cylinder engine. The model helped establish Kymco as a serious contender in the mid-size maxi-scooter market, rivaling offerings from Yamaha, Honda, and SYM.

What Buyers Should Know
Proven Engine Reliability
The 399cc single-cylinder liquid-cooled engine is known for strong long-term durability with proper maintenance intervals. Many owners report 30,000+ km with minimal issues when oil changes are kept on schedule.
Watch the Idle Issues
Some owners report rough idling and occasional throttle-by-wire glitches, particularly in early production models. A dealer firmware update and throttle body cleaning typically resolves these complaints.
Decent Resale Value
The Xciting S 400 holds value better than many competing maxi-scooters due to KYMCO's growing reputation and the model's feature-rich package at a lower entry price. It typically retains around 60-70% of its value after two years.

Used Buyer Review
"Brilliant value maxi-scooter if parts support doesn't scare you."
$4,500-$6,500 usedThe Xciting S 400 is one of those scooters that genuinely surprises you. Kymco built something properly grown-up here — the parallel-twin 399cc motor pulls smoothly from low revs, the suspension feels composed over rough tarmac, and that TFT dash with smartphone connectivity actually works. For urban commuting mixed with weekend blasts, it punches well above its price point. Used examples from 2018 onward are the ones to target. That said, go in with eyes open. Parts availability is the big one — Kymco's dealer network is thin in most markets, so budget extra time for anything beyond consumables. The underseat storage is shallower than it looks in photos, and the windscreen buffeting at 70mph gets old fast on longer runs. Check the CVT belt carefully on anything over 12,000 miles, and inspect the coolant hoses on older examples. For the money, though? Seriously hard to beat. You're getting near-Forza quality at roughly 60-70% of the price. Just make sure your nearest dealer isn't three states away.
