That's roughly 31.9 kg heavier than the average touring motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2020 Honda GL 1800 Gold Wing / DCT spec sheet below.

2020 GL 1800 Gold Wing / DCT - Pros & Cons

Strengths

Strong power output: Peak output on the GL 1800 Gold Wing / DCT is 124.7 hp @ 5500 rpm and 170 Nm @ 4500 rpm of torque - strong numbers for what it is.
Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
Accessible seat height: At just 744.2 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
Large fuel range: With a 21.1-litre tank, this isn't a bike you'll be stopping for fuel every hour - a real asset on longer trips.
Low-maintenance final drive: Shaft final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

Age-related wear: No particular mechanical concern flags for the GL 1800 Gold Wing / DCT - condition on any used example comes down to how well it's been looked after.

Wear Points & Servicing Notes

Cooling system servicing

With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.

Fuelling & injector care

Fuelling on the GL 1800 Gold Wing / DCT comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Brake disc and pad wear

2x 320mm discs 6-piston Nissin calipers up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by Double-wishbone front-suspension system w/Showa shock absorber up front and Pro-Link system w/ Showa shock absorber at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Shaft final drive on the GL 1800 Gold Wing / DCT removes chain and belt maintenance entirely - the trade-off is a little extra unsprung weight and periodic gear-oil changes.

Handling the weight at a standstill

The GL 1800 Gold Wing / DCT's 356 kg kerb weight is worth factoring into how you handle it at a standstill - parking-lot manoeuvres need a bit more deliberate technique than on a lighter machine.

GL 1800 Gold Wing / DCT - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2020 Honda GL 1800 Gold Wing / DCT should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept GL 1800 Gold Wing / DCT settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a GL 1800 Gold Wing / DCT's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

A GL 1800 Gold Wing / DCT that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
