BMW K 1600 B specifications

BMW · Touring

Total Motorcycle says thanks to the revamped engine control unit the K 1600 B now develops its 160 hp nominal power an impressive 1,000 rpm earlier than before. While the increased maximum torque of 180 Nm is available at 5,250 rpm.

It says you also enjoy unleashing the power of the legendary six-cylinder engine from one second to the next, that a comfort package adds Keyless Ride and Shift Assistant Pro for more relaxed cruising, and that the whole bike has been geared to the perfect tour, from the footboards to the cockpit.

What the retune means

Peak power arriving 1,000 rpm earlier means the engine has the same output lower in the rev range, so the bike feels stronger in the everyday range where a tourer lives. The 180 Nm at 5,250 rpm figure is high for the class, and it is why the K 1600 B pulls without downshifting.

At 758.4 lb road ready it weighs almost the same as the K 1600 GT (756.2 lb) but sits lower, with a 29.5 in seat against 31.9 in.

Against the K 1600 GT and the American baggers

The B is $1,810 cheaper than the GT ($25,075 against $26,885) and has a seat 2.4 in lower. Harley's Street Glide and Indian's Challenger are the bagger rivals, with V-twins where the BMW has six cylinders.

Price and weight beside the American baggers

Harley-Davidson lists the Street Glide at $24,999 and Indian lists the Challenger at $27,999, against BMW's $25,075 for the K 1600 B. The weights are stated on different bases (BMW road ready and fully fueled at 758.4 lb, Harley in running order at 811 lb, Indian in running order at 842 lb).

So the gaps cannot be read as exact, but the direction is clear: the BMW is the lightest of the three and sits close to the Harley in price.

Its seat is 29.5 in unladen, while the Harley lists 26.4 in laden and the Indian 26.5 in. The BMW’s unladen seat figure cannot establish the mounted height relative to laden figures on the other bikes.

Buying notes for the bagger

Test the seat first. It is 2.4 in lower than the GT. But the bike is still a big one.

Sit on it and lift it off the side stand. Ask whether the retuned engine control unit is fitted to the year you are shopping.

Check the service history for the six-cylinder's regular intervals. Read the owner forums for the model year, not just the brand.

A bagger that stays mostly on the road needs less protection than a GT.

The K 1600 B suits a rider who wants a smooth, powerful, low-seat bagger with BMW's technology. Check reach to the ground and the ability to lift it off the stand before choosing this heavy touring bike.

2027 BMW K 1600 B questions

How much power does the BMW K 1600 B make?

Total Motorcycle says the retuned ECU delivers the 160 hp nominal power 1,000 rpm earlier than before, with 180 Nm of torque available at 5,250 rpm.

How tall is the BMW K 1600 B?

BMW lists a 29.5 in unladen seat height, which is about 2.4 in lower than the K 1600 GT's 31.9 in and easier for a shorter rider.

What does the K 1600 B comfort package include?

Total Motorcycle says the comfort package features Keyless Ride and Shift Assistant Pro for more relaxed cruising.

Test the seat first. It is 2.4 in lower than the GT. But the bike is still a big one. Sit on it and lift it off the side stand. Ask about the comfort package, because Keyless Ride is a real convenience with gloves on. Ask whether the retuned engine control unit is fitted to the year you are shopping. Check the service history for the six-cylinder's regular intervals.

Look at the tires, since a heavy bagger wears them quickly. Read the owner forums for the model year, not just the brand. A bagger that stays mostly on the road needs less protection than a GT.

The K 1600 B suits a rider who wants a smooth, powerful, low-seat bagger with BMW's technology. It is heavier than most rivals, so a shorter rider should sit on it first.

What the bagger layout changes for the buyer

A K 1600 B is a lower-seated bagger choice within BMW's six-cylinder range. The published 29.5-inch seat should be tried in person: saddle width and the reach to the foot controls still affect how easily the rider can hold and manoeuvre the bike. Someone comparing it with a GT should sit on both in the equipment configuration being offered.

A different seat fitted by a previous owner can change that comparison even when both advertisements use factory specifications.

The B's silhouette does not establish its passenger equipment. Inspect the passenger seat, footrests, back support and luggage fitted to the specific example. For a bike advertised with Grand America equipment, identify the actual package and its load instructions. A touring accessory can make the luggage arrangement more useful, but it also occupies part of the permitted carrying allowance.

Start with the bike's own load label and account for rider, passenger, accessories and packed cases together.

Screen height is a meaningful difference from the GT. Look through the riding position rather than judging wind protection from the parked profile. A rider who prefers an open view may value the lower arrangement; another may plan an accessory screen for longer trips. Establish the mount and screen actually supplied with a used bike.

A worn or scratched screen can affect the view at night even when it looks acceptable in a daylight sales photograph.

At the listed $25,075 starting price, the B is $1,810 below the GT's $26,885. Keep that comparison at base-price level until both written offers identify their packages. A cheaper advertised B with the accessories the buyer needs could be the better purchase, while a heavily optioned B can exceed a minimally equipped GT. Financing terms and trade allowances can obscure that distinction, so obtain a cash-price comparison before looking at a payment.

The shared engine does not remove the need for a model-specific inspection. Ask about reverse operation, electronic suspension where fitted, heated equipment, locking and the service record. Demonstrate the controls while stationary using the handbook. For a machine intended for long trips, finding an intermittent luggage lock or a screen fault before purchase is more useful than being reassured that another owner's inline six has been reliable.

Parking requirements deserve the same attention as road comfort. Consider the place where the bike will be backed out, the surface under the stand and the width of the route through a garage. A low seat helps with leg reach, but the six-cylinder machine remains substantial.

A short stationary fitting on a showroom floor does not reproduce an awkward home parking position with full luggage. Work through that practical route before committing to the bagger arrangement.

Inspect the bagger's storage as equipment

Open each fitted case, test the latches and identify the keys or central-locking functions that operate them. Look for repaired mounting points and verify that removable parts seat and release as intended. A seller's description of generous luggage does not tell the buyer whether a case is damaged or whether its key is missing.

For a planned overnight trip, check access to the bag that will be used most often, then follow both case-specific and motorcycle-wide load limits when packing.
