2010 Suzuki Boulevard M90

Posted on by 9

Suzuki has accorded a lot of attention to performance cruisers in these last few years and so have been introduced models such as the entry-level M50 and their ultimate demonstration of power, the M109R . But their famous Boulevard line of cruising motorcycles didn’t feature anything in between these two models, something that would fill in the big gap and keep consumers hooked to Suzuki…until last year’s Suzuki Boulevard M90. The bike carries on to 2010, so let’s find out more about it.

 

Introduction

Suzuki Boulevard M90

The name says pretty much all in this case. The Suzuki Boulevard M90 is a clear and efficient derivation from the mighty Boulevard M109R , while the design and engine configuration come as confirmations to everyone’s suspicions. Smaller both in dimensions and displacement, the M90 is almost offended when designated for the middleweight power cruiser position. You see, there’s nothing in-the-middle about that 1,462cc V-Twin and with great power and acceleration inherited from its bigger sibling there’s also nothing to stop it from becoming the best cruiser that $10K can buy.

Competition

But in order for that to become reality, the competing models ask for yet another survey.

Honda VTX1300

The Honda VTX1300C easily fits in this category as it is practically built around a 1,312cc V-Twin motor and has the looks of a bad boy. Although not that much into performance cruising as the engine is carbureted instead of fuel-injected, the VTX1300C is a class favorite mostly because of Honda’s build quality and the affordable starting price ($10,199).

Suzuki Boulevard M90

Star’s V Star 1300 is an even stronger competing cruiser as the 1,304cc, liquid-cooled V-Twin with four-valves per cylinder features a fuel-injection system that is also most likely the reason of it going a little over 10k. Base MSRP is $10,290.

Suzuki Boulevard M90

But for those who want to stick to Harley-Davidson, the Nightster comes with a $9,999 starting price and much to offer for the money: a rubber-mounted 1,200cc Evolution engine and a new low profile with chopped fenders in Harley’s characteristic style.

Exterior

Suzuki Boulevard M90

Getting back to the Boulevard M90 we can’t help but mention how great this bike looks mostly because of the M109R inspirations. Everything from the headlight to that custom-like taillight seems like Japanese handicraft, while the Black, Red color schemes couldn’t have been more appropriate for this model as they enhance the amazing fit and finish.

The style is modern and aggressive, perfectly suitable for the performance that the still massive V-Twin engine is capable off. With a pair of chopped-up fenders on top of the cast aluminum alloy wheels and drag style handlebars, this bike is no stranger to drag racing or at least that’s the impression they’re trying to get (and manage pretty well if you ask me).

The 4.7 gallons fuel tank, on which the instruments are attached, features smooth flowing lines introducing us to a well padded seat positioned only 28.2 inches from the ground. As seen, the bike is low (but the manufacturer doesn’t mention the ground clearance) and pretty long (94.1 inches), like any veritable cruiser. And if we’re still at it, why not say that it definitely isn’t a night rod if you know what I mean. There are a whole lot of chromed pieces (handlebar, mirrors, instruments housing, engine, exhaust, rear fender ornaments etc) which lighten up the appearance, especially on the Black painted one.


Press Reviews

Suzuki Boulevard M90

"The M90 is surprisingly easy to lever off the stand for a 700 lbs bike, which is aided by the friendly 28-inch seat height. Though the 4.8-gallon tank appears massive from any angle, the general appearance of the M90 being a bike-too-big evaporates from your mind after the first couple of intersections." – motorcycle

"The liquid-cooled, 8-valve V-Twin is arguably the highlight of the new M90 despite a small 14-percent loss in displacement over the M109R. While the latter boasts an oversquare (Greater bore than stroke) engine, engineers altered the personality of the M90 engine by going undersquare (bore < stroke)." – moto123

"Most power resides at low engine rpms, though pulling from extra slow engine speeds produces a bit of chatter. But the V-twin pulls quite strongly, providing plenty of arm-stretching acceleration. And not only does it ride more smoothly, the fact that it weighs roughly 40 lbs less than the M109R improves handling and enhances maneuverability." – motorcycles.about

"The M90 behaves rather well, despite its curb weight of 723 lbs. With enough careful momentum shifting and forethought, this low-slung cruiser can hold its own against most technically challenging canyon roads." – ultimatemotorcycling

"Overall ride quality was smooth, with the KYB coil-over rear shock and 43mm inverted fork working in conjunction with the plush padded seat to provide plenty of comfortable riding miles. It handles better than your average cruiser, benefitting from Suzuki’s choice of a 200mm rear on the back end, and can be ridden aggressively into corners until scraping a peg." – motorcycle-usa

"Aggressive riders will like how much fun the bike can be when ridden hard, while easy cruisin’ types might wish for a little more plush in their ride. It’s not long before a hard-ridin’ type will start dragging the footpeg feelers, but thankfully that’s all that drags for awhile. We were hoping that the rear suspension would be easily adjustable for different situations..." – motorcyclecruiser

Price

Considering Suzuki’s suggested retail price of $10,599 for a 2009 model year and also the fact that the bike carries on virtually unchanged, we don’t have reasons to believe it will drift further away from the competition in this concern.

Conclusion

We could simply say that Suzuki has definitely filled the gap that worried them so much and we won’t be wrong, but in these cases the smallest model can be easily shadowed by the one from which it was derived in the first place and the work would have been in vain. Still, despite the small price difference, the public has reacted positively to the introduction of the all-new Boulevard M90, so Suzuki can worry no more.

I really wanted to buy one of these M90’s so went to my local Suzi dealer, he had one with only 1990 km on it, so I took if for a test ride, at 120 kmph the speedo stopped working, then half a mile further on the bike failed completely and I had to park it up. Walked a mile back to dealer in hot sun with full protective riding gear on! The drive shaft sounded like it was trying to disconnect from the gearbox when the bike did run, I’m gutted that a bike that looks so good could be so crap at under 2000 klm. Looking for something better.

I have enjoyed several long distance rides and the comfortable level is magnificent. But I must say the article above and the comments really are accurate. My m90 does have a low speed stutter that makes my city cruising a little uncomfortable and I hang in gears regulary. Once on the hwy this a truly and enjoyable bike. But if I where to do it all over again. I would consider a Victory also because there only 2009/2010 I am already having problems locating parts and accesories.

MY TRANSMISSION ON MY M90 IT HANGS UP IN 3RD GEAR. I ALSO HAD A PROBLEM AT A STO SIGN WHERE THE TRANS WOULD NOT SHIFT AND WAS HUNG IN 5TH GEAR AFTER ABOUT 10 TO 15 MIN OF TRYING TO GET IT TO SHIFT THE SHIFT LEVER FINALLY WENT DOWN WHEN I TRIED TO TAKE OF THERE WAS NOTHING I STARTED ROLLING BACKWARDS AND THERE WAS A METEAL GRINDING SOUND I TRIED SHIFTING AGIEN THIS WENT ON FOR 30 MIN BEFOR I COULD CATCH A GEAR AND GET MY BIKE TO A TOW TRUCK . THE DEALERSHIP KEEPS SAYING THERE IS NOTHING WRONG AND NOW THAT THE WARRENTY IS UP PROBLEMS KEEPS HAPPENING MORE OFTEN I WOULD NEVER OWEN ANOTHER M90 OR ANY BIKE IN THE BULIVARD LINE UP EVER AGIEN THIS BIKE HAS LEFT ME STRANDED IN THE MIDDLE OF NOWHERE 5 TIMES . SO RIDE THE M90 AT YOUR OWEN RISK

I purchased a 2009 M90 in February 2011. It has turned out to be the worst shifting bike I have ever ridden. Taking the bike to the Suzuki dealer doesn’t help. The certified Suzuki mechanic on staff says that is the way it was designed.

Twice now, I’ve narrowly escaped serious injury while in traffic because the transmission either won’t downshift from 3rd gear or it won’t upshift into 2nd gear. I’m sure there is a design flaw with this motorcycle’s transmission and Suzuki is refusing to address it.

@Boiseid, I’m not really familiar with bikes. But what you have said is kind of convincing because I’m planning to buy one next year. BTW, I don’t get what do you mean by "very strong but not so powerful". Kindly explain thankssmiley

I have owned an M90 for 2 years now and I love this bike! It’s beautiful. The power is substantial. The handling is amazing for a big cruiser. The stability on the highway—even in traffic—is stellar. The gas mileage is very similar to the 900 v-twin I replaced it with (so long as I’m not pushing it to its limits). I would recommend this bike to anyone who is looking for a very strong, but not ridiculously powerful cruiser that also enjoys riding at a healthy pace through the turns of their favorite mountain road! As for the problems noted by the reader above: To me, the ride is definitely not ROUGH, and I have never had the clutch chatter or issues seeing my guages. Hope that helps!

Hmm, they’ve been asking for designs like this the frame, motor, and wheels are really top of the class.

I have a new M90. The review info herein is quite detailed but I cannot recommend that the M90 be purchased. With 800 miles on my M90 I find that the ride is ROUGH, the instrument panel on the headlight cowelling is difficult to see clearly AT NIGHT. But the major problem is the vibration/chatter/shutter when going thru the gears. If you stay in low gear no problem but when you start shifting up, when the clutch is released you experience an annoying vibration/chatter, whether you are going slow or fast. The dealer says that it is "the nature of the beast". Others experience the same problem. When I want to sell who will buy a bike with such a problem. Surprised that Suzuki would market a machine with this problem. Anyone else have this problem.
DO NOT BUY AN M90. Tomtorske

Darn! The motorbike lights up. smiley ^^^
