Hello everyone, so I've got my mt10 and I'm starting to ride it at faster speeds now but I get a lot of head buffeting when I'm going faster than 80 mph. I using an older shoei rf900 helmet. Anyone got any ideals on how to deal with this. I've been looking at the new shoei x14 helmets but I don't want to spend that kinda money if that's not going to really help that much.
One other thing also. when riding at high rates of speed like 100+mph the bike feels a little unstable kinda like it doesn't want to track straight or its floating side to side. I do weigh 300lbs. Is it a nature of the beast type of thing or do I need to have the suspension up for my weight?

I don't think a helmet is going to have as much of a change on head buffeting as a windscreen would. I would look into windscreens instead. Basically made dealing with the wind a lot easier when I got a better windscreen.
As a big guy, yes absolutely suspension and even tire pressure are going to be a big deal for you. Most sportbikes are setup for like 160 LB people.
Suspension should always be set up for your weight and riding style. With your weight the rear suspension is certainly being taxed, you need to tighten things up front and rear, that should help but may not settle things completely. I notice no instability at speeds of 85-100 mph, it's straight as an arrow. You might want to check the rear tire alignment, it could be off a bit. And make sure your tire pressures are in range.
Head buffeting is a personal thing, often it will bother a rider and other rider's don't feel it. If you are coming from a bike with more wind protection it will take a while to get used to the naked setup of the MT-10. I only rode it about 30 miles before I put on a Powerbronze shield and I don't notice any head buffeting wearing an HJC RPHA-10 or 11 Pro helmet. Some people like the naked look and don't want to put on a screen but a screen does quiet things down in the cockpit. I wouldn't count on a new helmet solving the problem.

At 225-230lbs, I don't notice any kind high speed unsettling. I asked in your other thread, where are you in socal? I can hook you up with a really good suspension tuner if you don't want to tackle it yourself. It will only cost $50. Unless he suggests replacing components. At your weight setting sag correctly might require stiffer springs. After he set mine up, the bike feels night and day different, suspension is much stiffer than before as well.
@peripaticmike I'm located in the north west corner of orange county. How much do you think a rear spring would run out of curiousity?
I guess I'll just have to get used to the head buffeting because I don't want a windscreen hahaha.
I'm curious what do you guys run your tire pressure at. I was really surprised when I read the manual and it said to run I think 42psi in the rear tire. I've always ran my tire pressure anywhere from 30 to 35psi on on my old gsxr and Harley.
Hey Bigkurka, first of all, please define head buffeting. If you don't have any aftermarket or accessory windscreen on your FZ/MT-10, head buffeting should be non-existent. I'm afraid what you're describing is simply wind resistance. You only get head buffeting with windscreens, which is your helmet getting whipped by the wind in every direction; very annoying. That's exactly why I now chose a naked bike with no wind protection anymore. After owning dozens of bikes, I never found a windscreen without buffeting; just some worse than others. If you don't want any buffeting with a windscreen, you'd need a HUGE one... and that defeats the purpose of riding, at least for me. Of all my bikes, only my GL1800 with the windscreen all the way up didn't have any buffeting, but it was a barn door. Anyway, a very easy way to know if you have buffeting or not is to stand on the pegs. Try that. If you don't feel any difference, like I certainly don't, then you have no buffeting. Finally, with a naked bike, you have to certainly slow down compared to a faired bike, which I'm ready to do. I'm going on my first trip tomorrow, and will also play with speeds to see what is sustainable without fatigue. Just like you mentioned, should be around 80 mph, which is more than enough. I used to cruise at 100 on my previous bikes, but much rather cruise at 80 and feel faster, and don't risk getting a ticket (still have a perfect driving record). Since I'm still breaking my bike in (97 miles at the moment), won't go faster than that this time, but in the future, it'll have to be in short bursts only. And I MUCH prefer that than a freaking windscreen. My challenge tomorrow will be to get 130 miles out of a tank, or risk not making it back. Ha ha. So won't certainly speed on the way to Gila. Will take all back roads, to finish the break-in. Oh, and with your weight, you need the recommended 36/42, or something very close to it. I set mine to 33/36, but I'm 160, never a passenger, and only a small tailbag on the pillion. Good luck.
When I first got my FZ, I was running an old Arai Profile helmet. I didn’t ever get any buffering, but the wind would beat the hell out of my chest when riding in some windier areas. When riding between 80-100 mph, the wind would get under my helmet and try to lift it off my head. I guess that’s what I get for being a being a bigger dude, weighing in @ 270lbs and 5’11”. I suppose replacing the cheek pads would help as well. But instead, I decided to go with the Arai Defiant, which was designed more for naked/cruiser bikes. It has a bigger chin piece that hangs lower than the profile which helps deflect the wind. Recently, I have added a Puig touring windscreen which moves the air from my chest to my chin area and still got some buffeting. I went another step and added the clip on Puig visor. Now, the wind hits at about eye level with little to no buffeting. I haven’t had the chance to take it above 80 with that particular setup and I probably won’t have a good chance until next spring. I am not crazy about the looks with the windscreen, but the extra protection is nice. I am considering pulling it off for my regular commute/rides around town, and putting it back on before longer trips to help reduce fatigue. I’ll attach a pic below. Regarding the way it drives... straight as an arrow. My first instinct would be to check the alignment of the back tire as well.
Hi there elptxjc, I would describe what I'm sensation that I'm feeling is like my head is slightly bouncing side to side. No I do not have a windshield or any aftermarket screen and I don't want one do personal tastes. It's not a super bad thing it's more of an annoying thing. Also I don't feel the wind getting under my helmet and trying to lift it either. I rode a soft tail Harley for many years with open handle bars at speeds at and above 80 and never had this sensation on my head/helmet. I know on the Harley I sat lower in the saddle but the wind still hit me right in the face. This is why I was kinda thinking it could possibly be a helmet issue. I see all these different style helmets with different shapes and rudders on them and stuff. Also to throw out there I'm 6' tall.
Hey, I thought you were blaming the bike. Ha ha. Yeah, for higher speeds you need an aerodynamic helmet, but even an old RF900 should be fine on that department. Weird. At 6', it's definitely not the bike. Went for a long ride today for the first time (5' 10" here), and I get 100% clean air. Having said that, air is not always clean, as when you get buffeted when passing semis, for instance. I have a Shoei GT Air, and today experienced a bit of buffeting when the wind (it was windy) hit me at a certain angle on the way back, whether sitting on the bike or standing up, so even with a good helmet it's possible to sometimes get a bit of buffeting. But I changed my speed and it went away. It was nothing like the buffeting you get with a 'bad' windscreen, so not an issue for me. Only slightly annoying. I'd get a new helmet buddy. Yours is probably not that protective anymore; remember they lose protection with age, regardless of use. The good news is even cheaper helmets are as good as the premium ones now, but unfortunately, they don't fit my stupid head. Only the Arais, which I don't like, and the Shoei GT Air and the racy X series, but they're too noisy. Sold an X-11 for the GT Air, and it's a much better helmet for me, even though it lost a bit of ventilation that I like in summer, but they're just too darn noisy, even with earplugs. If you need advice on helmets, I'd go to webbikeworld.com. They have a ton of information on helmets. Good luck.
Sounds like something is wrong, even at 130-140mph I don’t get any buffering and it’s as planted as a rock, I guess it depends what you are used to. I had a cross tourer that did what you describe and it was horrendous your vision would go so you could not see because of the head movement just horrible from a bike that is built as a tourer. it turned out to be air pressure coming up around the forks and screen took the screen of and no problems just bad design and depending on the height of the rider if you hit the sweet spot then you were in for a crap ride. I know it is a simple one but have you checked Tyre pressure for the vague feeling?
Yeah, racing helmets will always be the best... if you can stand the noise. The main reason for that is they're designed to also be aerodynamic when rotating your head, which is not the case on most others. Or at least at a lesser degree. And THAT is the reason 'lesser' helmets might buffet a little with strong side winds. I really like my Shoei GT. Haven't ridden this bike above 95 or so due to break-in, but without strong side winds, it's super stable and very quiet compared to my ex-X12. And only very mildly annoying with strong headwinds, like I experienced on my last trip, and only above 80, so not a big deal at all. It was waaaay worse with windscreens, so not pleasant in any condition, really. I have to mention something more about aerodynamics of a helmet: You have to have your head in the proper position for it to be effective, and you can easily test that by moving your head up and down, and feeling/hearing the difference. If you're holding your head more upright than normal, then helmet is not going to work the same. Worth checking that out too. Like I mentioned before, the best test to make sure you have no part of the bike that is contributing to buffeting is to stand on the pegs, where you for sure will have clean air. Yamaha did a great job with that micro fairing, making sure no turbulent air would come out of hitting headlights, and other parts in front, to your head/neck. So basically if your bike is stock, your problem is with your helmet, period. Finally, looks like Fastback89 also misinterpreted the OP, like I did. He wasn't complaining about the bike, but his helmet.

willbuybikes: Hi evitzee, thanks for responding, it looks like the switch has fixed it. The luggage wasn’t full, it worked fine and the bike handled beautifully through the tight, twisty roads. The luggage is Ventura from NZ. I had a professional setup my suspension.

willbuybikes: It seems to be worse when it is full of fuel and opening the filler cap changes nothing. Apparently the dealer bench tested the fuel pump and said it was fine.
Apr 14, 2019 2:56:49 GMT -7
willbuybikes: I believe the switch replacement has fixed the cruise control problem. As for the starting issue, I suspect I will have to wait another 6 months to see if it is fixed, as we are heading into winter. I always assumed it was fuel related.

willbuybikes: Hi RedAndBlack, thanks for responding, no I have not cleaned my chain on the race stand but my mate with an MT-10SP has and he had the warning light come on and couldn’t change ride settings, like engine mapping. I only oil my chain that way and not long..
