Both are Trident roadsters with the same seat height, tank and riding position. The real difference is the engine and the hardware: the 800's 798cc triple pulls harder through the middle, with an upgraded Showa fork and floating front discs.
Choose the 660 if…
- You want light, easy fun every day.
- You ride mostly around town and on back roads.
- You want a lively triple that's never too much.
Choose the 800 if…
- You want more pull through the midrange.
- You ride fast roads and take longer trips.
- You want the upgraded fork and floating front discs.
Which one fits your riding style?
Here's where the difference shows up on the road.
Around town
Both are light and narrow, and the 660 is just 7 lb lighter. Reviewers say the 660 has torque for days for such a small engine.
The difference: Both are easy in town. The 660 feels a touch lighter.
Weekend back roads
On Ortega Highway, reviewers found the 800's 61.9 lb-ft pulls hard out of every corner, and the upgraded Showa fork gives it more control when you're pushing. The 660 is a riot at any pace.
The difference: The 660 is lively. The 800 is stronger.
Longer trips
The 800's extra midrange makes a run up the 5 easier, with less shifting. Both have the same seat and the same 3.7 gal tank.
The difference: For road trips, the 800 makes it easier.

Is the Trident 800 worth the step up?
It comes down to how much you want.
If you ride town, the coast and the occasional canyon, the Trident 660 is lively and light, and it's plenty.
If you want stronger pull everywhere and the upgraded suspension and brakes for faster roads and longer trips, the Trident 800 earns its keep. The step up is $1,250 in MSRP.
Our advice: Sit on both, then ride the 660 first. If you find yourself wanting more, the 800 is waiting.
The best way to decide is to sit on both, back to back. We'll have them side by side for you.
