Both give you the timeless styling, the comfortable upright riding position and the character that make a Bonneville special. The real difference is how each one feels when you pull away from a light, merge onto the freeway or spend an afternoon on your favorite roads.

Choose the T100 if…
- You ride mostly around town, along the coast and on weekend back roads.
- You like smooth, easygoing power more than outright acceleration.
- You want a bike that feels involving without being demanding.
- You want the classic Bonneville look, sound and feel in a bike that's a touch lighter.

Choose the T120 if…
- You ride the freeway regularly or cover longer distances.
- You want stronger acceleration without reaching for a lower gear.
- You often carry a passenger or ride with luggage.
- You value twin front discs, a sixth gear and standard cruise control.
Which one fits your riding style?
Here's where the difference shows up on the road.
Around town
Both sit you upright at the same seat height, and both are easy in traffic. The T100's 900 twin is smooth and willing, and the bike is 11 lb lighter. The T120 pulls harder from every light without trying, though in town you'll rarely use all of it.
The difference: The T100 gives you everything you need around town. The T120 keeps more in reserve.

Freeway and longer trips
Both cruise comfortably at freeway speeds. On the T100 you'll reach for a lower gear to pass, with five speeds to work with. The T120's bigger twin, sixth gear and standard cruise control make a long stretch of the 5, or a run up the coast to Big Sur, more relaxed.
The difference: Both make the trip. The T120 makes it easier.

Weekend back roads
On Ortega Highway or Angeles Crest, the T100 rewards a smooth rhythm and picking the right gear, and it's a lot of fun doing it. The T120 drives harder out of every corner, with 77 lb-ft against 59 lb-ft, and its twin front discs bring more stopping power when the pace picks up.
The difference: The T100 is engaging and easygoing. The T120 adds pull and braking.
Riding with a passenger
Both carry a passenger. Add a second rider, a hill or a short freeway on-ramp, and the T120's extra torque does the work without revving the engine hard.
The difference: Two-up now and then, the T100 is fine. Two-up most weekends, choose the T120.

Is the T120 worth the step up?
It comes down to where and how you ride.
If a great Saturday is a run up PCH, lunch on the coast and the long way home, the T100 is every bit as well built and evocative as its big brother, and you may never want more.
If your rides take in long freeway stretches, mountain roads or a passenger, the T120's extra torque, twin front discs, sixth gear and cruise control earn their keep. The step up is $2,500 in MSRP.
Our advice: Don't pay for performance you won't use. But don't underestimate how much you'll enjoy the T120's extra pull if longer rides are part of your plans.
The best way to decide is to sit on both, back to back. We'll have them side by side for you.
Questions riders ask
Is the T100 powerful enough for the freeway?
Yes. It cruises comfortably at freeway speeds. With 64.1 hp and five gears, you'll downshift to pass more often than on the T120, which has 78.9 hp and a sixth gear.
Which Bonneville is better for shorter riders?
Both seats sit at the same height, 31.1 in. The T100 is 11 lb lighter, which you'll notice most when you push it around the garage. Come sit on both and see how each one feels.
