GL 570 Ultra vs GL 991 Ultra: which touring motorcycle is better in Oman

Damaged asphalt, a gravel patch, a steep ramp into a gas station — none of it should worry you if the bike sits high enough. 190mm or more gives real breathing room. It won't turn a touring bike into an off-roader, but it means you're not white-knuckling every rough patch worried about scraping the underside.

Around 60 horsepower is a decent line in the sand for a full-size tourer. That's enough to sit comfortably at highway speed, pull off an overtake without drama, climb a long grade, and still have something left over once you've loaded up luggage and a passenger.

Horsepower on its own doesn't tell the whole story, though. What matters just as much is torque low and mid-range — a bike that has to be wound out near redline just to feel responsive gets tiring fast on a long ride.

There's no universal right answer here — it depends entirely on where you actually ride.

• 17/17-inch setups lean road-focused
• 19/17-inch is the practical middle ground for mixed surfaces
• 21/18-inch shows up on bikes built with a real off-road bias

If your riding regularly wanders off good tarmac, a bigger front wheel genuinely makes gravel and rough roads easier to live with.

Nobody wants to plan a trip around where the next fuel station is. A reasonable target is 350 km or more between stops — though actual range shifts with speed, load, wind, and traffic, so tank size and fuel consumption together are the honest way to estimate it, not either number alone.

Loaded with luggage or carrying a passenger, suspension has to absorb repeated hits without getting unsettled. Longer travel helps on mixed roads, and adjustable preload and damping let you dial things in as the load changes from one ride to the next.

Hours at highway speed, stop-and-go traffic, heat, extra weight — all of it adds thermal stress an engine has to deal with. Liquid cooling keeps operating temperature steadier through all of that, which matters a lot more on a touring bike than it does on something built for short rides.

Long descents, wet roads, heavy traffic, the extra weight of a loaded bike — touring conditions ask a lot of brakes. Solid hydraulic discs paired with ABS is the combination that actually holds up, cutting the risk of a locked wheel when you're braking hard with more weight on board than usual.

The longer the ride, the more comfort actually matters. Look for real wind protection, some shielding from spray and road grime, a riding position that doesn't fight you, and low vibration at cruising speed. Small ergonomic annoyances that barely register in the first hour start to wear you down by hour five.

Payload matters a lot more here than on a bike meant for short solo rides. A touring machine often has to carry the rider, a passenger, luggage, riding gear, and travel equipment all at once — so payload capacity and weight distribution for two-up riding are worth checking, not assuming.

Both motorcycles are built around a steel tubular frame and follow the same basic suspension layout: inverted telescopic fork at the front + swingarm with a monoshock at the rear.

Their dimensions are not identical, however. The larger motorcycle stretches and raises this basic formula to suit its greater output and more substantial touring role.

The similarities extend to braking hardware. Both bikes use Brembo components with dual 320 mm front discs, a 260 mm rear disc and ABS at both ends.

That is particularly relevant on a touring motorcycle, where braking performance has to remain predictable on long descents, with luggage, or when carrying a passenger.

The difference between GL 570 Ultra and GL 991 Ultra

The engine performance is where the difference between the two models becomes most obvious.

When comparing the GL 570 Ultra or GL 991 Ultra engine, the key difference is performance reserve.

The GL 991 Ultra's torque peaks nearly 1,000 rpm later than the GL 570's, which means its power delivery stays stronger further up the rev range — useful for sustained overtaking or two-up riding at speed.

With almost double the torque at a higher rpm, the 991 is better suited to carrying a passenger and luggage without losing composure on long hauls, while the 570 stays more comfortable revving through its narrower, lower-output band.

The gap in top speed (150 vs 220 km/h) reflects more than raw displacement — it points to a chassis and gearing setup on the 991 built specifically for sustained high-speed stability, not just outright acceleration.

The dimensional differences reinforce the same idea.

The 570 is 29 kg lighter, 40 mm lower at the seat and 35 mm shorter in wheelbase.Those differences should make it the more approachable option, particularly at low speeds. Its 795 mm seat height also makes it the more approachable option for shorter riders.

The GL 991 Ultra, with its 835 mm seat height and larger overall dimensions, is better suited to taller riders or those who prioritize long-distance capability, additional load capacity, and a more substantial touring platform.

When it comes down to GL 570 Ultra or GL 991 Ultra comfort, it's really a question of body size and riding style rather than one bike being objectively more comfortable than the other.

Fuel range is one area where both motorcycles comfortably meet the demands of long-distance riding.

The GL 991 Ultra actually burns more fuel per 100 km, but its larger tank more than makes up the difference — the numbers work out to roughly 47 km, or about 11%, of extra range over the 570, despite the higher consumption. In practice, that means fewer fuel stops on a long ride, even though the bigger engine is working harder the whole way.

Touring often means carrying much more than the rider alone, and this is another area where the two models begin to serve different needs.

The GL 570 Ultra has a listed maximum load of 180 kg.

The GL 991 Ultra increases this to 220 kg.

That 40 kg difference can become significant once a second rider, luggage, riding equipment, and accessories are added.

For predominantly solo touring or lighter luggage, the 570's capacity may be entirely sufficient. For frequent two-up travel or longer journeys with more equipment, the 991 provides substantially more headroom.

There is no universal winner because the two motorcycles solve slightly different touring problems.

• primarily road-based touring;
• a lower 795 mm seat;
• less weight to manage;
• a 17/17 road-oriented wheel setup;
• sufficient touring power without moving to a near-liter-class engine;
• more than 400 km of theoretical range.

• substantially more power and torque;
• stronger performance with passenger and luggage;
• a higher 220 kg load limit;
• longer theoretical range;
• 210 mm ground clearance;
• a 19-inch front wheel for more mixed-surface flexibility;
• greater reserve for high-speed and long-distance riding.
