Hello all, this is my first post so here goes.

I am looking to get back into the biking scene and am extremely surprised and excited at how well received the M50 bikes are. Everyone I talk to says they are awesome bikes, from harley guys to street riders.

Anyways, I am wondering how the M50 will fare at freeway speeds? I live in San Diego and everyone drives 70 to 85 mph all the time. So if you guys, and a few girls on here i see, have any input it would be appreciated.

Also, not that I am condoning this behavior nor am I asking for a test run, but does anyone happen to know the top speed of the M50? Basically for passing or merging i think this would be a useful statistic to have before purchasing.

Thanks,
Chris

Yeah it will cruise at highway speeds no problem. Trust me I've made a 2700 miles run on I-80 (75mph speed limit). As for the top speed. I have had it up to 117. Speed-o reads 120. She'll do it on a slight hill I'm sure.

if you're buying the M for speed, you're buying the wrong bike. You don't buy an 800cc cruiser for speed.

That being said, the M's fairly quick, and torquey down low, so it feels quicker than it is. I cruise in at 75-80 on my morning commute without issue, and she doesn't really start to gasp a little bit until you hit 95-100 or so. I've been up to an indicated 120, but lets face it, that's closer to 100-105 real speed.

Yup, speedo error plays a bigger part at these speeds.

My biggest recommendation for highway speed cruising is get a windshield, even if it is just a little one.

The other thing I noticed is when I pulled the baffles out of mine it seemed more relaxed at those higher speeds. This could just be a sound thing, but it might be a backpressure thing too... maybe a little of each. Not sure if that's an option in California.

An '07 M50 will haul a 350lb guy up to indicated 95 mph, not sure how much was left after that, I was at wide-open throttle catching up to a buddy on a sportbike.

thanks all for the info, i am not trying to buy a cruiser to race. I just didnt want to be cruising at 70-80 and have nothing left over that. the fact that it will get up to 100 is plenty fast enough, especially when factoring in the wind i would imagine. thanks again.

Just wanted to see if anyone was paying attention. ;)

I got the Memphis Hellcat shield and works excellent for me on the highway. I got it set up so I feel no buffeting. The first time I experienced strong side winds it was a little scary, you can really feel the bike being swayed and to me feels like the wheels are going to be blown right out from under you.

I use to ride at around 120 km/h. The speed limit is 100km/h on the highway in Canada, but everybody is driving up to 20 km/h faster. The engine sounds very well at this speed and isn't stressed at all. This with a light passenger (my wife).
I had the bike up to 140km/h and way more left in the acceleration. At 120 in the 5th I am at 1/2 of the acceleration position.

Windshields??? No way, just get used to riding without.

Wind really isn't that bad unless you're doing 80 into a headwind. Then you get to look like a real weirdo trying to tuck like you're on a sportbike. :)

Aha, I see. KPH, well that makes more sense.
And yes I do not one to be one of those guys. The ones who are tucking in like they are riding a GP bike on the freeway, makes me laugh every time I see one.

Thanks for the great info, you have eased my doubts about using the bike to commute occasionally to and from work. Thanks for all the welcomes, you guys have a great forum here. I think I will stick around for a little while longer.

Yes, sometimes is confusing. But keeping in mind that this bike's top speed should be somewhere around 11x MPH (~18x KPH), a cruising speed of 120 can be only in KPH.
The wind is indeed a problem if you don't have a windshield and its windy. On windy days, cruising at 120 KPH is a real pain for me (no windshield). I try to avoid highways on these days. The bike is very stable and the engine doesn't feel the pressure of the wind, but my head is like a ping-pong ball and my neck hurts after some time due to so much fighting to keep the head straight!:lol4:
But keep in mind that Canadian highway can be reeeeeally windy!

I have Hit 150 KPH - 160 KPH (93mph - 100 mph) easy over a short distance, but after that you need to have a long straight as the torque and power start to level out. I have found that it is fun to duck low like a sport bike guy (although weird looking) and you feel like you need to hold on as the wind is strong with out a windshield.
So for me I have done 160 KPH (100 mph) pretty easy, not to often, as it is really not needed, but it is fun to do now and then for short periods.
I have read somewhere that the max is 188 KPH - 194 KPH (117 mph - 120 mph) , but that must be over a long straight as the design of the torque and power curves are for quick low end power not high rev power.

I feel very comfortable cruising at 120 KPH ( 75 MPH ) at 140 kph ( 87 mph )the wind is not comfortable, but you can get used to it. I do not have a shield.

i took a longish trip (1000km) and i'll tell you one thing.

get a windshield for the long trips... i was worn out from the wind, not the ride!

at the high speeds (140kph+) i felt like i was going to get ripped off the bike due to strong head and cross winds, yet the bike was still very stable at those speeds.

My M50 will do 80mph all day long and tops out at an indicated 107mph carrying my 275lbs. I also have a windshield.

Here is a short video of my bike at 120 kph (~75mph). You can hear the engine is not so stressed at this speed. I find this speed suitable for highway cruising. No vibrations, excellent handling, a little too much wind in your face sometimes, very good roll on acceleration if you need it. I ride almost always with my wife as passenger.

YouTube - Suzuki Boulevard M50 at 120 km/h

Enjoy!

Ride safe!

Indicated top speed of M50, at least 120mph.
YouTube M50 almost TOP SPEED

If it is any consolation, my BMW R1150RS could go and indicated 110mph before aerodynamics made the Beemer unstable. Motor police officers claimed they could get their BMW R1150RTP-R1200RTP to 125mph, but the motorcycle was highly unstable at this speed. 110mph was top speed that felt safe.

My Harley Road King Classic at WOT would also only do an indicated 110mph.
