2020 Baggers Spec Chart Comparison

This all started with our recent Bagger Battle between the two juggernauts in the field: The Harley-Davidson Road Glide Special and the Indian Challenger Limited. In just nine days, that story garnered enough views on MO to make it our ninth-most read story of 2019 – and it was posted on December 23rd!

In lieu of the logistical nightmare that is putting seven motorcycles together for a test – especially since we’ve already ridden all of them – in this spec chart comparison we’re going to swap the Indian and two Harleys for the Challenger Limited and updated Road Glide, respectively, and take a look at the numbers. All the other bikes in the field haven’t changed much, if at all, since we rode them in 2018, which should give us a chance to see how far the new Harley and Indian have leapfrogged the field – or if they simply inch away.

Let’s get right to the heart of the matter here. Engines define a motorcycle, and nowhere is this more true than in the cruiser category. Making this comparison interesting is the wide array of engine sizes in this match-up. Bringing up the rear of the field is the Moto Guzzi, with a “paltry” 1380cc – mounted transversely, no less! But what the MG lacks in displacement it makes up with a total of eight valves, four spark plugs, and a huge 104mm cylinder bore – second only to the Indian’s 108mm cylinders. The result is 78.9 hp at 8000 rpm, more than the Kawasaki (68.7 hp) and Yamaha (75.2 hp). Of course, the tradeoff is a torque figure of 72.7 lb-ft at 2400 rpm. Last in this group by a wide margin.

From there the other V-Twins bump up in displacement quite a bit, starting with the 1700cc Kawasaki Vaquero, 1769cc Indian, 1854cc Yamaha, up to the 1868cc Harley Davidson. What’s impressive here is how much horsepower the Indian punches – 95.0 hp at 5,000 rpm – despite its small-ish engine. [We should note here that the Challenger MO dynoed had significantly lower numbers and didn’t rev as high as those in other magazine’s tests. Indian tells us our tester was a “preproduction” unit, whose ECU cut the spark at 5000 rpm. The PowerPlus engine is supposed to make max horsepower at 5500 rpm (122 crankshaft hp), and redline at 6500. – Ed.] Liquid-cooling definitely helps, as does its single overhead cam (instead of power-robbing pushrods), eight valves, and aforementioned 108mm pistons. Also huge in this category is its sportbike-like 11.0:1 compression ratio. On the torque front, its 111.9 lb-ft at 3,300 rpm is the most in this group, including the six-cylinders!

Ah, yes. The duo of six-cylinders. Both BMW and Honda come into this segment with the K1600B and Gold Wing, respectively, boasting not one, but six pistons going up and down. The BMW is the smaller of the two, at 1649cc, with the Honda coming in at 1833cc. If you’ve been paying close attention, the Harley Road Glide, while down four cylinders, trumps both of the metric machines in displacement. No matter, as both the BMW and Honda trounce all the others in the field with measured horsepower numbers of 131.8 and 102.1, respectively. Torque numbers are close, with the K1600B pulling 106 lb-ft and the Honda at 106.4 lb-ft.

Of course, the riding dynamics of a V-Twin versus a six-cylinder are vastly different, as explained in the Big Dam Tour story above. While the V-Twins deliver a rumbling pulse, the BMW and Honda give you silky smooth refinement. Hammer on the throttle, though, and the torque will quickly whisk you away, no matter what you’re on.

Considering the Bagger Battle and Big Dam Tour stories reveal all there is to know about the respective machines, the real question is how the new Road Glide and Challenger stack up against the old guard in the bagger category. Judging by the numbers, both bikes more than hold their own (except against the six-bangers). Especially the Indian. It seems remarkable what the Challenger can pull off despite its displacement deficit. The scorecard ratings reflect this, too. Despite being scored during separate tests, both the Harley and Indian engines tied in the ratings at 87.5%, far surpassing the 79.8% the highest-ranking BMW scored in the Big Dam test.

When it comes to suspension and ride quality, there are no big revelations the Harley or Indian bring to the table. The Harley rides on a 49mm fork with twin shocks in the rear while Indian went for inverted forks 43mm in diameter and just a single shock out back. The others similarly follow suit with telescopic forks and shocks. Once again, the BMW and Honda stand out – BMW for its Duolever front suspension and the Gold Wing for its double wishbone front end. For a bagger’s intended purpose, shredding miles in comfort, it could be argued either method of quelling road imperfections is better than your standard fork/shock combo.

In the real world, the V-Twins still perform well. As Evans explains: “While you can tell the difference between the non-traditional front ends and the old, reliable telescopic fork (of both the standard or inverted variety), the front suspensions of all the bikes are more than capable of handling the rigors of travel – both on the interstate and two-lane highway. However, what truly differentiates the suspensions of these bikes is the shocks. The quality of these baggers’ ride breaks down pretty much where you’d expect it to once you look at the specs for the rear suspension travel. The Harley ranks dead last, and with 2.1 inches of travel, it should come as no surprise. With the rest of the baggers having 50%-100+% more rear suspension travel, the results pretty much sort themselves out by the length of the stroke that the shock(s) have to deal with road conditions. Not surprisingly, the BMW and the Honda, with their transcontinental touring bike roots, smooth the hard knocks the best.”

Baggers are meant to shred miles, right? To do that you need a lot of gas in the tank. Looking down the line, we see the BMW leading the way with its massive 7-gallon tank. The Yamaha’s 6.6-gallon capacity is a close second, with the new Road Glide and Challenger tied at 6 gallons. Ever since it was introduced, Honda was criticized for equipping the new Gold Wing with only 5.5 gallons (Honda says the new Wing is more efficient than the last, cancelling out the slight drop in capacity from before), but this is still more than the Moto Guzzi (5.4 gallons) and the Kawasaki (5.3 gallons). In our testing, which typically features heavy right hands, here’s what kind of real-world mileage we’ve seen from each bagger:

As you can see, despite the Honda’s 5.5 gallons, the Wing’s increased efficiency is more than just marketing fluff, scoring the second-best fuel mileage in the group. Only the new Road Glide bests it, and only by one solitary mile. With a result that close, they’re basically nill. Despite its heft, the Yamaha’s still able to nab 40 mpgs. Impressive. Way in the rear of the pack is the Guzzi, maybe because you need to wring its neck and keep the revs up to stay with the group and have fun. Of course, more revs means more gas.

When it comes to heft, “only” 106 pounds seperates the lightest bike here, the BMW, from the Yamaha at the other end of the weight spectrum. It’s slightly more remarkable considering the K16 has three times the number of cylinders as the Eluder. But the K16 also utilizes lighter plastic compared to the gobs of metal on the Yamaha. After the BMW comes the Guzzi (795 lbs), then the Honda. The Road Glide (847 lbs) and Challenger (835 lbs) are among the heavier bikes here, with the Kawi slotting in just behind the Harley at 845 lbs. Generally speaking, light makes right on a motorcycle, but if ever there was a category where poundage was a non-issue, it’s this one. Who cares what it weighs; as long as it looks cool and stirs the soul.

On the surface, all seven of these baggers seem to be on a fairly even playing field as far as base price goes, with the Kawasaki’s $16,799 being the least expensive and the DCT version of the Honda Gold Wing bringing up the other end of the price scale. But let’s not fool ourselves into thinking anyone would buy a base version of any of these. Depending how wild you want to go, with the exception of the Moto Guzzi and Kawasaki, each of these models can be accessorized to the moon from the factory, and the resulting price tag can knock on the door of 40-large. And that doesn’t include accessories you can find in the aftermarket…

If ever the saying “Different strokes for different folks” applies, it certainly does here. Seven different interpretations of a bagger – some traditional, others not – all excelling in their own ways. However, the point of this spec chart comparison was to see how the new Harley Road Glide and Indian Challenger slotted in with the pack. It shouldn’t have been much of a surprise, but the two are standouts in this category. Their combination of style, power, refinement and technology continue to be the benchmark others rate themselves against. But what do you think? Are the Road Glide and Challenger top dogs, or have we completely missed the boat (again)? Let us know below.
