    I also ride a street triple. So if i watched carefully, bottom out is 20mm from the bottom and the buffer should be at 40-45mm from the bottom? But for example, If take some preload out this might change the rider sag as well. What is leading? Greetings from the Netherlands. Love to watch your video’s.

    so my '05 R1 turns in way faster than i'm comfortable with, but once i'm at lean it feels sluggish to get to the absolute edge of the tire. now i did swap tires and got a higher tire in the rear(55 instead of the 50 that is factory size), that does increase the weight on the front i know that, however i cant increase the front height, forks are flush with the triple clamp up top. i assume my best option is to get a rear shock that has ride height adjustment and dial the rear ride height down a notch or 2. then again, i've only done 2 trackdays on this bike and it's so different from my previous trackbike, i'm still finding a good baseline setup for the suspension, setting sag to a certain book-number is too soft for my braking ability, i bottomed it on the first session. have a trackday planned next week, going to experiment a bit with compression and preload.

    Check shock sag and see if the shock is too hard or too soft. That might explain the "why" of the wheelie. Once the shock is set correctly for preload, rebound and compression - see how the wheelie occurs and if there is a difference. Is it harder to get the wheel to ride? If so, the bulk of the issue was the shock setting. The additional contributor may be fork rebound being too fast.

    I have a quick question on this. I have an S1000XR and I get a slight front end wobble at high speed cornering (90mph+ sweepers). Increasing the rear preload decreased this wobble so it makes me think it's a problem with the pitch of the bike. Usually increasing how much the forks stick out at the top make the bike more agile but less stable at speed due to reduced rake, but would it help with the wobble due to pitching the bike forward and putting more weight on the front? I don't really want to go higher on preload as the ride would be too harsh and other handling issues arise. The bike has electronic suspension and putting the damping into the sporty setting also helps a bit with the wobble but it's still present. The forks are currently level with the triple tree so there is no room to go down. Any help would be appreciated!

    @@greyanaroth As far as I'm aware the preload on the front forks is not adjusted by D-ESA or very minimally, basically when adjusting the preload it raises or lowers the rear for the most part, you can pitch the whole bike forwards (increasing rear ride height/reducing rake and trail). It's weird but it helps, despite on paper making the trail/rake smaller it should make the bike more nervous. It's not a perfect system by any means but I'd rather have 90% correct suspension 90% of the time than 100% correct suspension 10% of the time. The only issue really is with the head wobble in high speed corners when on the gas. This can be vastly mitigated but in doing so I cause other issues/discomforts in the handling, so I'd like to root it out as a geometry change, and retain fine tuning control from that point onwards. Basically as Dave says, you don't want to be at the end of adjustability, first you wanna get the bike generally right, then fine tune with adjustments. Right now (and I am really exaggerating) the bike is not set up right for me, so no amount of adjustment will fix it completely. It may be something I have to compromise on, after all it's a Sport tourer not a Superbike, but I want some confirmation to my theories or guidance before I start messing with the geometry.

    TORQUE SPECS!!!! A career spent working on German engines has proven to me that fastener torque and torque sequence are EXTREMELY important! The OE didn't pay some enginerd big bucks just to throw some random numbers in the book. 10:50 is a perfect example of why torque is important. Could've been over-torqued and with dissimilar metals the aluminum will deform and "bite" into the bolt. This is why if the head is looking like it'll round off before the bolt loosens up then a couple tappy taps on the head in line with the shank will help to release that "bite".

    Dave, so i watch lots of your videos, and what i understood so far - that factory version setups of all bikes is coffins???? i am surprised , no one ever sued any of manufacturers. and i never seen that any of them said - dont ride hour product before you take it to dave :) :) :) :)

    Suspension is a highly personal thing, just like lever positions, mirror position etc. Factory bikes are set up one way. That set up fits a very very very tiny subset of people. Usually 75kg 180cm perfectly average proportioned males. If you match all that, most bikes will probably fit you perfectly, however even at that point the suspension is built to a budget on most bikes and they have to make compromises between track vs road, good roads vs bad roads, twisties vs highways. Whilst the suspension maybe perfectly set up for your weight to ride good highways, they may be entirely inadequate for bumpy twisties.

    @@AntaresSQ01 no mate, still not agree with you - everything in the world(cars, pedal bikes, small air planes and etc. is build on average humans measurements. but any human can ride it without accident in any condition. and of-course, ergonomics and other little adjustments only would give more comfort and performance. but is no way, that if say you r 160 and 80kg you will get into accident (on any road and condition), just because you did not done all Dave's adjustments and ride stock bike!!! Tell that to any bike shop- see what they say - this would be against human rights to sell bikes if it was like that! who needs Dave's help- is track race drivers only, because it gives more performance where seconds matter. and just to add - so you say, i can not go to bumpy curvy roads on my stock bike??? no way i am going to change my shocks - than better to buy bike that has them already- i haven't been told in the shop not to go faster than 70km/h in not perfect road conditions when i bought it!!!

    @@labasrytas2876 i never said youd get into an accident, its just a correct suspension is confidence inspiring, a bad one is not. Bikes are more sensitive to rider weight cos the rider makes up 1/4 to 1/3 of the vehicle's gross weight, f9r cars this is usually 1/15 or less so your weight barely makes difference. That's all. The best example i can thing of is the MT07, forks pogo for anyone over 80kg, don't for people under.

    If you have an 800lb bike, the springs necessary just to carry the weight of the bike and have some sag will accommodate a much broader range of rider weights and still be in some acceptable range. Car example: If you throw 4 heavy set people in military Humvee, it's barely noticeable). If you take something lighter, the rider's weight starts to become a noticeable factor. Car example: throw 4 heavy set people in a civic and it goes from feeling light and stable to sloshy-body roll and the rear end resists coming around but when it does brake loose doesn't want to recover anymore. So let's look at a light bike and see why this just isn't possible to create a perfect in all situations: *Sprung for heavy rider:* If they spring it for a heavy 280lb rider, the spring is almost double what it needed for just the bike weight, has sag, damping etc. *Now a light 120lb rider hops on that bike. Because it was sprung for double the bike weight, almost if not all the sag disappears. The ride will be stiff and harsh. The rider will probably think that's because they don't have enough skill and that the suspension is meant to be pushed more, where it will feel better. And they are even partially right! But, because the person doesn't weight enough, the springs overcome the rebound damping, so bumps become quick jolts that bounce the bike just a bit. The lack of sag means the suspension can't react to drop the wheel for road imperfections, so that means either wheel loss of traction (just what you want in a corner, right?). *If the rider tries to take corners in a neutral very tame balance, the front end will skitter on bumps and want to wash out. *If they take corners with aggressive trail braking to keep the front end weighted, the overly stiff suspension will send rapid shocks of weight shift front to back and forth, giving rapid shocks of traction & loss of traction, while the rider is loading the front tire more. Does that sound beginner friendly? *Also, if the front wheel can't drop to accommodate road imperfections, how do most tank slappers initiate? Oh yeah, people coming down from a wheelie and the wheel being at a different angle that the travel of the bike... So you can see why manufacturers don't want to even approach those risks with a 10ft pole. So let's flip it, *Sprung for a light rider:* Light bike with a light rider, the rider is approx 1/3 of the bike weight, sag and dampening set, beautiful. Now throw a heavy rider on that, and the bike squats. *Everyone can instantly tell the bike is overloaded with the weight. The bike squishy both undersprung and underdamped, and divey. The rider will feel like it is hard on the bike and they naturally take it easier. *They don't feel confident braking hard because feeling like you are going over the bars is uncomfortable, non-confidence inspiring. (sadly, actually makes it harder for a new rider to learn) *Going too fast over hard bumps bottoms the suspension, and it bucks. You feel the shock through the seat, so you feel (and are) beating up the bike to push it on stuff like that. Again, this inspires to play it safe, take it easy. *the bike still soaks up light stuff, but when it bottoms, it is indeed dangerous -but, for most stuff it isn't dangerous if you are taking it easy *until you run into something unexpected, such as a pothole that either catches the front end when you panic brake or the back end bottoms and being underdamped tries to launch your lazy non-standing butt over the bars **overall, this is a much safer outcome than the severely over-sprung and overdamped bike, and when it fails, it can be blamed on the rider, because they should have been more tame, seen, and reacted to the more extreme pothole, bump, etc. (and indeed, more riding skill and more alertness would probably have passed unscathed, with a few muttered expletives at the inadequate suspension that did in fact try to kill you) *So what do manufacturers actually do?* They go mostly to the way-soft condition, but out of concern for too light riders, they compensate by weak damping. *It's the perfect one-size-fits-no-one solution.* Most people can hop on the bike without killing their selves, and it generally pushed riders to ride more safely. How did we get here? Why don't manufacturers included more travel, more compression and rebound settings range, and include spring options by default? It's our fault, the riders (well, not me, because I don't buy new, ha ha) People like to drool at the expensive/premium option, shun the low option and end up buying the middle option (it's why store-branded inferior options exist in grocery stores - they drive you to buy the middle option for just a little more money). Sure, some splurge or always buy the premium option, and some are cheap and always buy the lowest cost (however they factor that), but 80-90% of people buy the middle option. So take 50years of companies offering the premium package for $3000more and people cheaping out to the standard package and guess what? You get more of what you endorse. So they just stop putting the cost/time/effort/parts support into better suspension, because it doesn't help their sales or bottom line at all. *If their bike came standard with those options, you'd be comparing their competitors $8,000 bike to their $11,000 bike and despite the advantages, people would wish for but mostly buy the competitors "almost as good at a fraction of the cost" middle option. Am I going to change this long-standing trend? No, because I don't buy new. Imagining a conversation between me and the manufacturers: Me: "I'd like you to start adding___ and stop this____ and changing this____" Them: "Ok, how much are extra are you willing to pay beyond current price for those things?" Me: "erm, um,... well you see, that's the thing, isn't it..." So I'm not even really their customer other than as an influencer role and replacement parts.

    For anyone questioning how a bike can generally be considered well behaved, and then suddenly try to kill you, here is the notorious wr250r underdamped shock trying to kill someone (and how he addressed it). The bike is commonly touted as having better than average suspension, and it does, until it gets pushed just a little beyond the normal tame, and then it suddenly goes from soaking it up to aggressively trying to kill you: kzread.info/dash/bejne/nWyK0c-efJOsitI.html go to 2min16sec in that video and enjoy

    @@CatalystReactionSBW oh dave, it's a 2001 R1 and I just thought it looked better lol. The bike handled fine before, I just wanted a slightly more aggressive stance and didn't think it would change anything else. I was accelerating on the freeway, actual speed probably 85mph, I ran over a patch of uneven concrete and it started. Extreme head shake for what seemed like 5+ seconds. I had no control, just let off the gas and luckily nothing was in the direction I was drifting. I actually contacted you through Facebook and you informed me that slamming the forks caused a "shopping cart wheel" effect. This was maybe 6 years ago but youll be happy to know I still own the bike and she's doing just fine.

    Let off the gas? I keep thinking Keith Code; “when in doubt give it gas”. I had a bit of a nasty head shake as the weekend; I kept on the throttle. I was accelerating out of a corner, on the gas ... drifted a bit over the line (in the Highlands no traffic) and hit poor road surface and cat’s eyes 🙁. ... managed to keep on the gas! Big just powered through it. Hmmmm 🤔. It’s sort of a habit with me; hope I am doing the right thing 👍

    @@chriscarbaugh3936 ya I think you did it right. That was my first big one. The bike will do little ones sometimes but there's not even time to react before they go away. This one was nearly lock to lock. In the moment I really just didn't know what to do. It was a pretty helpless feeling because I had zero steering control and I was just drifting into the median. I just remember thinking "well, here we go, we're gonna crash." And it finally just went away at maybe 40mph or so. Idk if hitting the gas would've worked but in the moment it seemed like the exact wrong thing to do.
