The 350S is Zontes' muscle cruiser, built on the same 348 cc liquid-cooled DOHC four-valve single as the rest of the 350 range - 39.4 hp and 32.8 Nm, Bosch MSE 6.0 injection, an oil cooler and a slipper clutch. What separates it from the 350V it sits alongside is packaging: a rounded 16-litre teardrop tank, two litres more than the 350V, and a seat at just 750 mm, the lowest in the entire 350 family. It runs 43 mm inverted forks, a J.Juan four-piston radial front caliper, independent front and rear ABS, and a single-sided aluminium swingarm.
Two features that change what you should buy
First, the rider platforms are adjustable across two positions from the factory. Before buying forward controls or extended pegs, check whether simply moving the standard platforms solves the problem - a lot of 350S owners spend money on something they already have. Second, that single-sided swingarm. It looks superb and it makes conventional saddlebag mounting awkward: universal throw-over bags and two-sided pannier frames do not translate cleanly. Look for one-sided or swingarm-specific mounting when shopping for luggage on this bike.
What sells here
Backrests and sissy bars lead, followed by cruiser-appropriate soft luggage, comfort and gel seats for longer rides, and screens - the 350S is essentially unfaired, so anything above 110 km/h gets breezy. Cosmetically, the bike already has full LED lighting with DRL, backlit switchgear, a colour TFT with screen mirroring and tyre pressure and temperature monitoring, plus twin fast-charge USB sockets, so electronics upgrades are largely redundant. Grips, bar ends, mirrors and levers are the usual personalisation route.
Fitment
Covers the ZT350-S and the "S350" naming used in Spain and by UK dealers. Engine-side consumables are shared with the 350R, 350T, 350X, 350GK and 350V - filters, plugs, sprockets, chain kits, levers. Body, seat and swingarm-mounted parts are 350S-specific.
