Suzuki GSX-8TT Top Speed, Specs & Review (2026)
TL;DR
- The Suzuki GSX-8TT top speed is about 135 mph (217 km/h), but that is a published estimate, not a GPS-verified run.
- The 776cc parallel twin makes a claimed 82 hp and 57.5 lb-ft of torque, and the bike weighs 445 lb with a 31.9 in seat.
- No independent 0-60 mph or quarter-mile time has been published for the 8TT as of November 2026.
- US price is $11,149 MSRP, which is the biggest hurdle for this bike.
- Bottom line: it is a good-looking, comfortable, easy retro sportbike that rewards relaxed riding more than hard riding.
How Fast Is the Suzuki GSX-8TT? Top Speed Explained
The GSX-8TT top speed is roughly 135 mph (217 km/h), an estimate from Australian Motorcycle News (AMCN, 2026). It is not a GPS-verified number. I could not find an instrumented top speed run for the 8TT from MotoStatz, Cycle World, Rider, or MCN, so treat 135 mph as a planning figure.
Power is the limit here. The twin makes its claimed peak at 8,500 rpm and then runs out of steam, because Suzuki tuned it for midrange grunt rather than top-end rush.
The small handlebar-mounted fairing helps more than you’d expect. Ultimate Motorcycling (2026) reports that it pushes airflow over the rider’s helmet, and that the bike runs into triple digits on the freeway without a squirm.
Gearing is also friendly. Sixth gear is tall enough for relaxed cruising at 75 mph without the engine buzzing, which is where this bike spends most of its life.
What Is the Suzuki GSX-8TT 0-60 Time?
No independent 0-60 mph time for the GSX-8TT has been published as of November 2026. That includes the big US testers. Any number you see online is either a formula estimate or borrowed from a sibling bike, and I’m not going to invent one.
Here is what we do know. The engine pulls hardest low and through the midrange, the bike weighs 445 lb, and the up/down quickshifter keeps the power on between gears. That adds up to brisk, not violent.

How Much Power Does the GSX-8TT Really Make?
At the rear wheel, expect roughly 74 to 76 hp, not the claimed 82. Rider (2025) dyno tested a GSX-8S, which shares the engine, and got 75.9 hp at 8,300 rpm and 53.3 lb-ft at 6,700 rpm. The 8TT’s engine is unchanged, so a similar result is a fair assumption, but nobody has put an 8TT on a dyno yet.
Rider’s tester wanted another 20 to 25 hp and called the top end flat. That matches the feel of the engine: smooth and linear, with no vibration to speak of, but not exciting.
Fuel economy was 44.4 mpg in the same test, good for roughly 191 miles from the 4.3-gallon tank. Other testers report better range on easy highway rides, so plan on 190 to 240 miles depending on your wrist.
How Does the GSX-8TT Ride on Real Roads?
The 8TT rides like an easygoing everyday streetbike. The upright seating position is comfortable for hours, the clutch and gearbox are light, and Easy Start and Low RPM Assist make stop-and-go traffic painless. Beginners moving up from a 300 or 400 will find it friendly.
The cockpit is neat. You get a 5-inch TFT, a USB-C port, LED lighting and bar-end mirrors, which look good and keep your elbows out of the view. The quarter fairing and chin spoiler give it real racing-bike attitude without the racing-bike crouch.
Hard riding is where it gets tired. The fork has no adjustment, the rear shock only adjusts for preload, and damping is on the soft side for heavier riders. The stock Dunlop Roadsmart 2 tires give middling grip, and tight canyon corners overwhelm the chassis before the engine runs out of power.
The Nissin brakes are predictable but a bit short on feel. They stop the bike fine; they just don’t tell you much about the limit.
What Are the Real Drawbacks of the GSX-8TT?
The biggest drawback is price. Motorcycle.com (2026) calls the 8TT’s value hard to justify and says better bikes exist for the money. Rider put the MSRP about $1,900 above the GSX-8S that shares its engine, and what you’re paying for is mostly bodywork.
Other flaws are real too:
- Ground clearance is only 5.7 in, so hard cornering will drag hardware sooner than on many rivals.
- The suspension is basic, with no fork adjustment at all.
- The exhaust is quiet and mild, which suits neighbors more than enthusiasts.
- The rear end looks long and busy until you fit a fender eliminator.
If you want the fastest middleweight for the money, this is not it.
Is the Suzuki GSX-8TT Worth $11,149?
The GSX-8TT is worth it if you want retro looks, daily comfort and a friendly engine, and you’ll pay extra to stand out in the parking lot. It is not worth it if you want maximum speed or sharp handling per dollar.
It suits commuters, weekend riders and returning riders who want something easy and handsome. Track-day riders and anyone who dreams of a quick 0-60 should look elsewhere.
One seasonal note: the quarter fairing earns its keep in spring and fall, when cool air makes highway windblast tiring. Add a good set of touring tires before winter storage season and the bike gets better right away.
Suzuki GSX-8TT FAQ
How fast is the Suzuki GSX-8TT?
The estimated top speed is about 135 mph (217 km/h). That figure comes from a published estimate, not a GPS test. The bike cruises easily at 75 mph and has plenty of passing power at highway speeds.
What is the GSX-8TT 0-60 time?
No independent 0-60 mph time has been published yet. Suzuki doesn’t claim one either. We’ll update this page when a tested number is available.
Is the GSX-8TT good for beginners?
Yes, with a caveat. The power is smooth, the seat height is 31.9 in, and the electronics include traction control and ABS. At 445 lb it’s heavier than a small starter bike, so shorter riders should sit on one first.
What is the difference between the GSX-8T and GSX-8TT?
They share the same engine, frame and electronics. The TT adds a handlebar-mounted quarter fairing, a chin spoiler and a sport seat, and it costs more than the 8T.
What colors does the 2026 GSX-8TT come in?
The two US colors are Glass Sparkle Black and Pearl Matte Shadow Green. Both have gold wheels and racing-style stripes.
Specs and performance figures in this article are manufacturer claims or published estimates unless noted. Prices are US MSRP and vary by dealer.
