2009 Muscle Cruiser Shootout
Suzuki M90 vs Star Warrior: New blood versus the old guard

As the cruiser market grew along with the rest of the industry at near exponential rates over the last 15 years, so did displacement and the “performance” level of some cruisers. Now there’s an unofficial subset of this segment where the words muscle, power or performance may be used along side the word cruiser.Sure, performance cruisers still have most of that essential cruiser profile. But a lot of them also stop well, are agile, powerful enough, and comfortable enough to catch the eye of a consumer that may be considering an altogether different style of bike.
Witness Suzuki’s latest introduction, the Boulevard M90. During the bike’s U.S. launch this past fall in Monterey, CA, Mel Harris, vice president of American Suzuki Motor Corporation, says the M90 fills a gap that existed not only in Suzuki’s own product line, but also in the market.
New regime versus the old guard. 2009 Suzuki Boulevard M90 and 2009 Star Warrior.
So this got us to thinking. Is it possible this friendly bruiser can hold its own against a veteran of the class? The other party in this showdown is the venerable Warrior from Star Motorcycles. Entering its eighth year of production, the Warrior is a standard setter. The successful combination of comfort, style and performance is undeniable, and for its many admirable traits it won our 2007 Power Cruisers Shootout.
After eight happy years the Warrior is about to come under attack from a lesser-powered combatant, a combatant that has a strong race heritage in its big family tree. Will the Warrior finally lose favor with the cruiser masses? Let’s find out!
2009 Star Warrior $13,190 ($13,390 Onyx)
That’s 102 cubic inches of smooth, good looking power!
The Star Warrior is a founding member of the current generation of muscle bikes. Birthed in 2002 under the Yamaha banner, the Warrior we know today started life as a hot-rodded Road Star. It’s been updated here and there over the past few years but has remained largely unchanged. There’s no shame in staying the same for so long, especially considering the Warrior was the basis for five AMA ProStar Hot Rod Cruiser championships; the class was retired in 2006.
What really establishes the Warrior as unique among not only the cruiser crowd-at-large, but also among this narrower scope of power rides is its aluminum double-cradle frame and swingarm. Carried in that stiff but weight-saving frame is one helluva 1,670cc (102ci) V-Twin. It may be pushrod and air-cooled, but it’s potent!
After the first 20 or so miles switching between the Warrior and M90, guest tester and author of Riding Man, Mark Gardiner, made a sharp observation: “The two motors illustrate the fact that these bikes are a study in contrast.” However, Mark also quipped that there’s still no replacement for displacement, a long-held tenet of gearheads the world over.
• 1670cc (102ci) 48-degree, fuel-injected, air-cooled, OHV pushrod, 4-valve-per-cylinder, 5-speed with belt final drive; cable-actuated wet multi-plate clutch
• 97 x 113mm bore and stroke with 8.36:1 compression ratio
• Twin-bore dual 40mm throttle bodies
• Claimed horsepower and torque: 83.1 hp at 4400 rpm and 99.6 ft-lbs at 3750 rpm; measured rear wheel horsepower and torque courtesy of AreaP/NoLimits: 74.8 at 4500 rpm and 94.3 at 3700 rpm
Don’t be quick to dismiss the Warrior’s seemingly dated engine architecture like I did before seeing the dyno charts. Star endowed the Vee with large cooling fins, ceramic composite cylinder bore plating and a one-piece head cover for efficient heat dissipation. Knowing this and seeing nearly 95 ft-lbs on the dyno helped dispel the myth that a modern air-cooled pushrod engine will suffer the same power-scavenging losses from heat like V-Twins once did.
Despite its age the Warrior’s 1670cc engine doesn’t suffer from lack of power.
A little over 200cc in the Warrior’s favor doesn’t seem like it would necessarily serve the Suzuki a crushing blow. However, the advantage is clear if we factor in the Warrior’s longer stroke. An extra 5 horsepower is decent, but the nearly 12 ft-lbs more establishes the Warrior as the clear winner in the engine department. That is, if you’re just going by the numbers.
The Warrior has a distinct edge in the engine department.
What the..? How did a Canadian slip in on my watch?
Power delivery is V-Twin classic: torquey and linear. Trouble-free fueling is aided by two spark plugs per cylinder. With so much pulling power, lumbering along the avenue in fifth gear as low as 1,000 rpm is possible. The bike accelerates with authority even when in top gear at higher rpms. Not quite so characteristic of a Vee is how relatively vibe-free the Warrior’s engine is. However, the notchy tranny made finding neutral a chore. It’s the one legitimate sore spot in this mill.
• Aluminum double-cradle frame and swingarm
• 41mm KYB male-slider fork adjustable for preload; single under-chassis Soqi shock, pre-load and rebound adjustable
• Dual radial-mount four-piston front brake calipers with 298mm rotors; single two-piston rear caliper with 282mm rotor
• Five-spoke cast aluminum wheels with 120/70 x 18 front and 200/50 x 17 rear tires
• Rake, trail, wheelbase: 29.2 degrees, 5.11 inches (130mm), 65.6 inches
• Seat height: 28.1 inches
• Overall height, length, width: 93.9, 44.1 and 36.8 inches
• Wet weight: 650 lbs
• Observed fuel economy of 36 mpg from 4.0 gallon fuel tank
• One-year limited factory warranty
The Warrior’s aluminum frame and swingarm not only help contribute to the apparent 73-pound weight savings over the M90, but also provide rigidity, the benefits of which are a stable but forgiving ride. Enhancing the Star’s road manners is the reasonable 65.6-inch wheelbase (0.9 inch shorter than the Suzuki), a comparatively shallow 29.2-degree steering angle and a manageable 200mm rear tire. “Although it requires some effort, the bike turns well, is predictable, and has impressive ground clearance,” noted Mark.
The Warrior has a look all its own, a look that sets it apart from the clones.
The Warrior’s handling prowess is just as impressive as the power from its engine is.
Slowing and stopping is another strong suit of the Warrior. With a pair of radial-mount calipers, something current sportbikes have only seen for the past four or so years, the Warrior stops as well or better than any OEM cruiser available today. “The brakes are excellent, with good feel, a good initial bite, and moderate lever pressure–although I’d like to see the lever adjustable for my elf-like hands,” Mark said.
Ergonomically, and certainly stylistically, the Warrior doesn’t fit neatly into a cruiser box. “You sit on the Warrior, an impression exaggerated by the low headlight and instruments,” explained Mark. Noting that sitting at a standstill the low headlight placement makes the Star strike a bad-ass pose, Mark also countered that “at highway speeds, there’s a fierce wind blast.”
Speaking of instruments, the Warrior has a digital tachometer; the Suzuki lacks any kind of tach. Additionally, placement of the Warrior’s instruments puts them in plain sight. The M90’s tank console-mounted indicator and warning light cluster is often difficult to see through the chin bar of a full-face helmet. The annoying result is that you often don’t realize your blinker has been on for the past two and a half miles.
“The Warrior, stylistically, is the most resolved and most American metric cruiser… it’s not trying to be a Harley-Davidson. It’s doing its own thing,” said Mark as he summed up Star’s well-established performance cruiser.
Indeed, not many mass-produced Japanese machines have deviated from traditional cruiser styling quite like the Warrior. Nevertheless, the Warrior has a visual faux pas or two, like the charcoal canister that’s mounted on the lower frame (CA models only, of course!). Or the openly routed wiring shroud between the steering stem and fuel tank. And spark plug coils mounted in plain sight near the fuel tank detract from the Warrior’s overall appeal, cheapening what Star designers worked so hard for.
Despite those ticks, it’s hard to knock this founding father of fat powerband boulevard bombers.
2009 Suzuki Boulevard M90 $9,999
The M90 represents the next evolution of Suzuki’s Boulevard line, slotting in between the 805cc M50 and the 1,783cc M109R. Furthermore, it’s not just a re-tune of the Boulevard C90. The M90 has an “all-new” V-Twin set at 54 degrees (like the M109R), and is a four-valve-per-cylinder unit whereas the C90 is a 45-degree three-valve-per-cylinder engine.
Other differences include a higher compression ratio, larger twin throttle bodies, valve covers that are separate of the camshaft housing for allegedly reduced top-end mechanical noise, and a friction-reducing cylinder coating derived from GSX-R racing efforts. All these differences are meant to more closely resemble the 109’s engine character.
Couple this sportier engine with equally sporty and stable handling, give it nearly identical styling as the M109R, and Suzuki has a new performance cruiser with a rider’s wallet in mind.
• 1462cc (90ci) 54-degree fuel-injected, liquid-cooled, SOHC, 4-valve-per-cylinder, 5-speed shaft final-drive; cable-actuated wet multi-plate clutch
• 96 x 101mm bore and stroke with 9.5:1 compression ratio
• Twin 42mm throttle bodies with Suzuki’s Dual Throttle Valve (SDTV)
• Claimed horsepower and torque figures are not provided by Suzuki; Measured rear wheel horsepower and torque: 69.6 at 5100 rpm and 82.7 at 2900rpm
The M90 brings some higher-tech features like liquid-cooling and overhead camshafts to counter the Warrior’s extra 208cc. The cylinder bore difference is only 1mm, so the Star’s advantage comes via a longer stroke.
The M90’s engine is down a bit in displacement, so naturally it won’t have the Warrior’s bigger dyno numbers. But it makes enough power and torque that most riders should be happy with it.
“The Suzuki feels revvier and slightly anemic in comparison to the Yamaha,” Mark opined. Still, he could appreciate what the Suzuki’s engine is up against, saying that “it’s not weak in absolute terms, just by comparison to a larger and pricier alternative.”
The M90’s exhaust pipes were individually tuned and tested in sound labs to get just the right V-Twin note. They look snazzy, too.
It doesn’t take long at the helm of the M90 to note its spirited mill. Peak horsepower arrives at a higher rpm than on the Warrior. This is likely a result of overhead cams and higher compression allowed by liquid-cooling. Fueling was trouble free. Also, the engine is a little more visceral, as vibration from the rubber mounted engine is easier to detect than on the Warrior. This sensation isn’t necessarily a negative, but does add a little rawness to the Suzuki. Maybe you like that in bike engines; many folks do.
The Boulevard M90’s five-speed gearbox is matched pretty well to its power and torque, but feels slightly tall when cruising around town if you’re trying to lug third gear at low rpm. Once on the Superslab though, fifth gear feels more like an overdrive. The middleweight Twin can drone along comfortably like a touring bike, yet it still has enough power in reserve that overtaking autos isn’t a crapshoot. Shifting is classic Japanese quality, albeit with a little notchiness, but it’s not as persnickety as the Warrior’s tranny. Also noteworthy: we experienced minimal jacking from the shaft final drive.
Due to its smaller displacement this new metric cruiser can’t quite hang with the Warrior in a head-to-head power battle. But how disappointed could you be with almost 70 horsepower and over 80 ft-lbs of torque?
• Steel double-cradle frame and shaft drive swingarm
• 43mm KYB male-slider non-adjustable fork; single under-chassis KYB shock pre-load adjustable
• Dual Tokico two-piston sliding-pin front brake calipers with 290mm rotors; single-piston sliding-pin rear caliper with 275mm rotor
• Cast aluminum wheels with 120/70 x 18 front and 200/50 x 17 rear tires
• Rake, trail, wheelbase: 32 degrees, 5.08 inches (129mm), 66.5 inches
• Seat height: 28.2 inches
• Overall height, length, width: 94.1, 43.3 and 34.3 inches
• Curb weight: 723 lbs
• Observed fuel economy of 40 mpg from 4.8 gallon fuel tank
• One-year warranty
Suzuki chose not to include a tachometer on the M90, sticking instead with this stylish speedometer and basic indicator lights nestled on the tank console.
The Warrior includes an LCD tachometer and analog speedo; both are seen easily while riding.
The M90 can’t tout a lightweight aluminum frame and swingarm, but its ride is stable and precise nonetheless. Additionally, the Suzuki shares the exact same tire dimensions as the Warrior, but it also suffers from less ground clearance than what the Warrior provides.
The sense of balance a rider gets from the M90’s neutral handling is apparent within the first few miles of twists in the tarmac. Turn in effort is minimal for a bike in this category, but when it comes to parking lot speeds and U-turns the Warrior obliges ever so slightly more easily. Drag-style bars with a moderate bend put the rider in corner-attack mode on the M90 but not at the cost of being in a stretched-out maneuver-limiting position.
Ride quality from the front suspension is forgiving, yet not so soft that it numbs feedback from the road, or that steering input is lost in translation between the bars and tire. The M90 emulates the hardtail look pretty well thanks to the hidden preload-adjustable shock, but it also more closely resembles a hardtail’s ride. The M90’s ride out back isn’t as supple as the Warrior’s despite having the same 4.3 inches of rear suspension travel as the Warrior.
At first thought, the M90’s steel frame might’ve indicated a performance deficit to the Warrior’s all-aluminum chassis, but that wasn’t necessarily the final impression. Likewise, the M90’s basic two-piston sliding-pin brake calipers shouldn’t come anywhere near the Warrior’s radial-mount units. Surprise! Those sliding-pin jobs work pretty darn well. They provide more than enough power, but not the degree of sensitivity or ultimately as much force as the Warrior’s binders.
“The M90 has Suzuki’s typical ‘organic’ feel. You sit more in this bike, and there’s noticeably better wind protection,” Mark said. This sensation is interesting because the M90’s seat height is 0.1 inch taller (woo woo, big deal, we know…). But it also echoes Mark’s earlier comment that this is as much an exercise in contrast as it is in comparison.
Both motorcycles have large fuel tanks, but the M90’s tank seems more bulbous compared to the Warrior’s. No doubt the smooth round line of the tank is highlighted and complemented by the same bubbly shapes found in the front and rear fender as well as the headlight shroud. “The M90, in contrast to the Warrior, looks very ‘anime’ with its brightly colored bodywork, and there’s lots of reflecting surfaces everywhere.”
You sit more ‘in’ rather than on the M90, and there’s noticeably better wind protection.
On a bright note (pun intended) both motorcycles have attention-getting L.E.D taillights.
We know that looks mean a lot in the cruiser segment of the two-wheeled world, but put that highly subjective issue aside for a moment.
Next to styling, the big concern in most American rider’s minds is engine size and the numbers engines can produce. If you’re a spec-sheet jockey, the Warrior is, as it obviously should be, the leader. In this day and age of 2000cc engines, a 200cc difference between powerplants shouldn’t be much more than a blip on the radar of rider insecurities. But the dyno says the Star’s additional 200cc matter. All the more impressive for the Warrior is that it can get those extra 5 hp and 12 ft-lbs from a modern air-cooled pushrod engine.
Has the sun started to set on the mighty Warrior? With the introduction of the M90, Suzuki has given the market an option, and savings to boot!
Still, the dyno tells only part of the tale. Sure, we figured the Warrior probably made more power than the Suzuki, but it wasn’t glaringly obvious to us while riding that one bike was immensely more potent than the other. We couldn’t really be certain of the Warrior’s advantage until we saw the scientific results. If two riders like us that have wide frames of reference couldn’t feel a vastly superior advantage in power, how much less then will the beginning or average rider be able to perceive the differences?
Along the trip we also determined that the M90 comes dangerously close to, if not directly in some aspects, matching the Warrior’s handling, braking performance and ergos.
The Warrior has that tough-guy cruiser thing down pat!
Hopefully it became clear to you that Suzuki has made a competent and comparable bike to the Warrior. Furthermore, whether by sacrificing profit margin or through greater production volume or whatever else, Zook brought the Boulevard M90 to market at a substantial savings to the consumer. The Warrior’s styling is undeniable, and there’s a robust support system for this bike in the aftermarket. But is it really $3,200 more powerful, better handling or sexier than the Suzuki?
Of course, there’s always another opinion. Mark…?
“As they used to say in ancient Rome, ‘De gustibus non est disputandum.’ I feel that the styling and fit and finish of the Midnight Warrior reflect its premium price in the metric/muscle cruiser category. I found myself really enjoying little rides down to Starbucks or the library. However, another person might compare the two bikes and be drawn to the Suzuki.
I feel that the performance of the Warrior, both in low-rpm cruising applications and when ridden in a more sporting manner, justifies its higher price. I see it as the choice for riders with more experience and bigger budgets. The M90 is a great value and probably more appealing to the novice.” – Mark Gardiner
