2021 BMW K1600 Grand America Overview

For 2021, BMW offers the K1600 Grand America as a touring motorcycle with 1649 cc on tap. The 2021 BMW K1600 Grand America is built around an In-line six, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 12.2:1. Internally, bore and stroke are 72 x 67.5 mm. Out on the road, the K1600 Grand America delivers 118 kW @ 7750 rpm of peak power and 175 Nm @ 5250 Revolutions of torque. Flat out, it's quoted at 162.5 km/h. In everyday use, the 2021 K1600 Grand America tips the scales at 336 kg, carries a 26.50-litre fuel tank, offers a seat height of 750 mm and spans a 1618 mm wheelbase. That's roughly 11.9 kg heavier than the average touring motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2021 BMW K1600 Grand America spec sheet below.

2021 K1600 Grand America - Pros & Cons

Strengths

Strong power output: Peak output on the K1600 Grand America is 118 kW @ 7750 rpm and 175 Nm @ 5250 Revolutions of torque - strong numbers for what it is.
Accessible seat height: At just 750 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
Large fuel range: With a 26.50-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 drive (cardan) (final drive) final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

Age-related wear: No particular mechanical concern flags for the K1600 Grand America - 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.

Valve clearance checks

Valve clearances on Double Overhead Cams/Twin Cam (DOHC)-equipped engines like the K1600 Grand America's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.

Brake disc and pad wear

Double disc. ABS. Four-piston 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 BMW Motorrad Duolever up front and BMW Motorrad Paralever 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 K1600 Grand America removes chain and belt maintenance entirely - the trade-off is a little extra unsprung weight and periodic gear-oil changes.

Frame & chassis check

The Aluminum bridge-type frame with load-bearing engine chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

Handling the weight at a standstill

The K1600 Grand America's 336 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.

K1600 Grand America - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2021 BMW K1600 Grand America 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 K1600 Grand America settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a K1600 Grand America'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 K1600 Grand America 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.

Valve clearance service

There's no reliable seat-of-the-pants way to tell if a K1600 Grand America's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
