ornery Posted June 25, 2015 Share Posted June 25, 2015 I've heard from more than a couple people, and read in books, you probably have a little more traction than you think. So, I'm always trying to lean a little more on each ride. Seeing where the limit really is. This morning I was hardly pushing it, and the rear tire slipped, causing me to gasp a bit. Just didn't expect it at all, and without knowing what went wrong, I'm going to be pretty timid with cornering for a while. [video src=https://www.youtube.com/watch?v=unhG_CVc-Hc&feature=youtu.be] No brake applied. 6:00AM, 50°F, 6 miles of riding 35MPH prior. Roads dry, no sand or gravel. Tires new and inflated exactly at Yamaha's spec. Wasn't leaning that much, IMO. Was on a line to stay in my lane until it cut loose. “The real cycle you're working on is a cycle called yourself.” — Robert M.

Premium Member wickedtwister Posted June 25, 2015 Premium Member Share Posted June 25, 2015 It's probably due to the cold temps. Not sure which rear tire you have but cold grip can be a problem but 50 isn't that cold. By the way where are you it's 80 here at 6 am... Also many miles on tires? I had similar issues with new tires but once they are "broken" in they are fine. I was riding and the road had nice high speed rolling hills speed limit 55. Came across a long sweeper and there was a solid line of gravel on the road that I hit mid lean. I started to slide really bad and a quick jab to the pavement with my brake foot righted the bike but man was that a pucker moment! Link to comment Share on other sites More sharing options...
NICKY NEON Posted June 26, 2015 Share Posted June 26, 2015 also check your tire pressure should be about 34 psi Link to comment Share on other sites More sharing options...
Tyler Jane Posted June 26, 2015 Share Posted June 26, 2015 Yikes, pretty scary. I've been afraid of this. I keeping trying to lean more and more and so far I haven't had this happen (as long as I'm not touching the rear brake). But I guess it's bound to happen eventually.

cndnmax Posted June 26, 2015 Share Posted June 26, 2015 Probably gravel or something in the road, you can't always see it. Link to comment Share on other sites More sharing options...
Premium Member fz07fanboy Posted June 26, 2015 Premium Member Share Posted June 26, 2015 More than likely is because the tire wasn't warm enough. Also your posture when leaning can make a difference. it also looks like in the video you may have went over a damp/wet section on the right side of the corner. There also looks what seems like what i call tar snakes (seals cracks in the road) in the road that you may have turned on as well. Link to comment Share on other sites More sharing options...
pantheraleo Posted June 26, 2015 Share Posted June 26, 2015 It's possible you picked up a bit of oil or something before the turn and it reared its head then. Cold temps and damp road conditions are possible other suspects, but after 6 miles, the tires should be warm enough for a turn like that one. Don't let it freak you out. My rear has slipped quite a few times. It's okay, you just ease off (NOT release quickly) the throttle and ramble on. O judgment! Thou art fled to brutish beasts, And men have lost their reason. Bear with me. My heart is in the coffin there with Caesar, And I must pause...till it come back to me. Link to comment Share on other sites More sharing options...
bmwpowere36m3 Posted June 26, 2015 Share Posted June 26, 2015 Best to ride it out… i.e., don't freak out. This is where dirt experience really comes in handy. Once you become accustomed to "sliding" around… driving on the street will seem tame by comparison. I went from street riding to dirt… boy that was an eye opener. Best advice is to never apply the brake (probably worst thing you can do) and either hold the throttle steady or very and I mean very gently and slowly reduce the throttle. Unless the entire turn is covered in gravel… likely you'll slip for a bit and then regain traction. Now if you hit an oil/gas/diesel slick or wet spot… that's tricky because the bike will very quickly slip out. You only have so much traction… I'd rather slide at a slightly higher speed, but have all the grip available to cornering instead of giving some of it up to braking. And if you're sliding, i.e., reduced grip, any braking generally will only make you slide more. I was ripping down a very hilly backroad and I "knew" the road was dropping off, but I was on the throttle hard and didn't lean forward…. pulled a wheelie over the crest of the hill/drop. Definitely a big pucker factor since I knew it was coming, but didn't really expect it. I've also slightly slid around corners, but mostly due to loose "road material" that still covers some of our roads from the winter (i.e., freeze, thaw and plowing knocked up a bunch of gravel-like material off the roads surface).

bmwpowere36m3 Posted June 26, 2015 Share Posted June 26, 2015 The video doesn't really show much of a slide and I don't see much counter-steering. However I'm sure you slid some. You cut the corner pretty close to the sidewalk and at the "apex" (near the sidewalk curb) there was a "darker" patch of asphalt (maybe wet, maybe not) and there seamed to be a few "bumps" mid-turn (either from tar snakes or roads patches) as well. It probably was a combination of outdoor temp, tire temp, maybe a wet spot, a bump mid-turn and jerky throttle (FZ-07's seem to be jerking when going from closed to open throttle).

ornery Posted June 26, 2015 Author Share Posted June 26, 2015 Which of you folks is Astrality84? He replied, "Most of those slips occur because the rider lets off the gas. The bike is then engine braking in the corner which is bad for traction." This may be it. Tires have 850 miles on them, and are perfectly inflated to Yamaha's spec on the swing arm. I went through the turn today very cautiously and looked for oil, sand or other contaminants on the road. It was perfectly clean, but it was foggy, so I suspected it may have a mist on the surface this morning, and didn't push it. Thanks for the input Astrality84, you've given good advice and encouragement. Only wish there was a “The real cycle you're working on is a cycle called yourself.” — Robert M.

Premium Member norcal616 Posted June 26, 2015 Premium Member Share Posted June 26, 2015 When the tire is under 3k miles old it's still kinda slippery in the areas that get used only when you corner from my experience...my stock tires are 3500 miles old and the cornering area of the tire is getting better as it ages...I find the rear brake on this fz is super strong... 2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW Link to comment Share on other sites More sharing options...
Guest Ralph Posted June 26, 2015 Share Posted June 26, 2015 Your only doing about 25 and to be honest I cant see anything amiss with the way the bike acts, those tar repairs can be very slippery and I think you felt the wheels cross them and that caused you to over correct a little maybe just jolted you confidence. Tyres are generally run in or what ever you call it after 100 miles but if you don't lean the bike a lot you can end up with quit large areas that have not made contact with the road so if you then suddenly start to lean it further you can end up cornering on what is untouched rubber. Trick is to progressively lean further over the first few miles on the new tyre not suddenly go from near upright to full lean. Link to comment Share on other sites More sharing options...
Premium Member speedingtickets Posted June 26, 2015 Premium Member Share Posted June 26, 2015 Was it sand? Dirt bike experience taught me to lay heavy on the throttle when going down. It is difficult to do psychologically. Link to comment Share on other sites More sharing options...
Premium Member jake Posted June 26, 2015 Premium Member Share Posted June 26, 2015 I've had a few myself on several surfaces recently I got caught in the rain I was going faster than I should and hit the lane stripes and felt the rear let go.

Cruizin Posted June 26, 2015 Share Posted June 26, 2015 When ya get more experience rear tire slip can be fun heading into a corner. Kinda like when we were kids and pulled the e brake in moms car to do a powerslide. Rear tire slip is ok, it happens and the thing to do is just go with it and not start hitting brakes. On dirbikes, we power slide most corners by hitting back brake to slip the tire out and then pin the throttle, which allows us to roost our buddies behind us with rocks. Take corners slow for a while and with more miles under your belt you will get used to it.

Guest GringoStarr Posted August 5, 2015 Share Posted August 5, 2015 Have you watched Twist of the Wrist II? I couldn't tell what your posture was from the video, but hanging body parts off the bike toward the inside means less bike lean and more traction. I assume a tire can lose traction because it has too little load. TOTW2 repeats something like this ad nauseum: " roll on the throttle evenly and consistently throughout the turn." This transfers weight to the bigger rear tire for more grip. Link to comment Share on other sites More sharing options...
Premium Member norcal616 Posted August 5, 2015 Premium Member Share Posted August 5, 2015 I never minded the rear tire slipping after all my years of dirt biking...I always keep the throttle steady if I feel the rear slipping...I will not quickly let off the throttle when I feel the rear slipping as it will gain way too much traction way too quickly... 2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW Link to comment Share on other sites More sharing options...
Beemer Posted August 5, 2015 Share Posted August 5, 2015 A little bump while in a turn, maybe some very fine crumbled asphalt you couldn't see. I did notice some patch work in that spot or even just some fine surface oil you couldn't see. Intersections are notorious for that. No one can say for sure what caused it because so many different things can cause it. Not taking any chances of anything slick in a turn, I always brake and down shift while going in a straight line before a turn and I'm at the speed I want to be at before I enter a turn, I don't lean it hard & fast, I lean gradually and I slowly roll on the throttle exiting 'after the apex', not through-out the turn. That's my way of being cautious. Beemer Link to comment Share on other sites More sharing options...
ornery Posted August 6, 2015 Author Share Posted August 6, 2015 Thanks for the input. First of all, this happened after only about thirty days of riding. Now that I have a whopping 1,400 miles under my belt, another incident like this wouldn't shake me up much. It probably was the edge of the tire not being worn in, along with not rolling on the throttle, or possibly even allowing it to slow during the turn. I've had it get squirrelly on me since then, and just accepted it. I think it would be a riot to throw a 250 pound dirt bike around, but I've come to terms with the fact this bike is too heavy to wrestle around.

RobMoore Posted August 6, 2015 Share Posted August 6, 2015 This bike isn't heavy, but it is undersprung and underdamped. I think your slip was from bouncing over the rough patch of road you hit cutting the corner the way you did. Link to comment Share on other sites More sharing options...
thomascrown Posted August 6, 2015 Share Posted August 6, 2015 I've lost both the front and rear tire, i just put weight on the outside peg to get the bike as vertical as possible. The more upright the bike, the longer you have to reacquire traction. Link to comment Share on other sites More sharing options...
ornery Posted August 6, 2015 Author Share Posted August 6, 2015 This bike isn't heavy...Pffft, this thing is too heavy to be ridden like a dirt bike. That was a rude awakening for me and that's where the gasp comes from.

Premium Member hobbs Posted August 6, 2015 Premium Member Share Posted August 6, 2015 I hit a massive gravel slick last week on a windy backroad. The bike came very close to eating an asphalt sandwich. It all happened so quick I nearly fell off the bike. But I managed to hang on and she recovered after sliding across the entire lane. Not going down that road again I tell you! Everything went braap. Link to comment Share on other sites More sharing options...

Thats not entirely true... but maybe its because of my size. Ive saved myself from some rather nasty spills by kicking off the ground. usually they involved dirt, gravel or slick/wet corners.
