Triumph Trident 660 vs Suzuki GSX-8S: Which Should You Buy?
Two middleweight nakeds, practically the same power - about 80 hp from the Triumph, 82 from the Suzuki - and only $654 between them at manufacturer MSRPs: $8,595 against $9,249. When the numbers are this close, the decision falls to the one thing the two makers did completely differently: three cylinders or two. That is not a trivia question. It defines how each bike feels every single time you open the throttle.

The triple. Smoother, rev-happier, lighter by ~12 kg, cheaper by $654, with a lower seat and a premium badge. The pick if character and sound matter, or if you are on the A2 pathway - Triumph's official restriction kit makes it the buy-once choice.

The twin. A bigger 776cc engine tuned for midrange shove, a planted, substantial feel on the road, and Suzuki's proven mechanical simplicity. The pick if effortless roll-on torque is your definition of fast.

Prices are manufacturer-published US MSRPs (Triumph and Suzuki), excluding destination and dealer charges; the Trident's Triple Tribute edition costs more. Power and weight are catalog approximations that vary by market and model year, and equipment such as quickshifters differs by trim - verify the exact spec locally.
Triple versus twin is the whole argument
Everything else on the table is a rounding error, so be honest about what each engine layout gives you. The Suzuki's 776cc twin is the low-effort motor: it makes its thrust early, pulls out of corners and past traffic without needing a downshift, and feels relaxed doing it. The Triumph's triple trades a little of that bottom-end for a motor that spins up eagerly, stays silk-smooth as the revs climb, and makes an intake howl that twins simply cannot - the reason Trident owners talk about the engine the way other people talk about music.
Neither is objectively better. Riders who commute and overtake buy twins and are happy; riders who chase revs on a Sunday buy triples and are happy. The mistake is buying one while wishing for the other's character.
Where the Trident 660 wins
The measurables, surprisingly - for the badge that is supposed to charge a premium. It is $654 cheaper, roughly 12 kg lighter, and sits 5 mm lower, which together make it the friendlier bike in tight traffic and the easier one to push around a garage. The A2 story is the clincher for European riders: Triumph's official restriction kit means an A2 rider can buy the Trident on day one and simply derestrict later, instead of buying twice. And it is the only bike in this price class that hands you a triple.
Where the GSX-8S wins
Substance and shove. The extra 116cc buys real midrange muscle that shows up in every roll-on, the chassis rides with a planted, big-bike composure the flightier Triumph does not try to match, and Suzuki's reputation for unburstable simplicity is worth something over a decade of ownership. If your riding is more about covering ground forcefully than chasing a redline, the Suzuki's case writes itself - and our GSX-8S vs CB750 Hornet guide covers how it stacks against the class value pick.
Which should you buy?
Buy the Trident 660 if the engine's character is the point, you want the lighter and cheaper machine, or you are an A2 rider planning the buy-once route. It is the rare case where the charismatic choice is also the rational one.
Buy the GSX-8S if midrange torque is what you actually use, you prefer a more planted, substantial motorcycle, or your Suzuki dealer is the good one nearby. It is the less romantic pick and it will not care - it will just keep pulling.
Ride both back to back if you possibly can. Three cylinders against two is the most audible, tactile difference in motorcycling, and ten minutes on each will tell you which side of the argument you were born on.
Still not sure which fits you?
The right call depends on your height, what you are stepping up from, your licence situation, your budget once gear and insurance are counted, and how much of your riding is commuting versus carving.
