Attack Performance

On the Trattle is brought to you by SportBikeRange. com. Perform it part, professional advice. Richard Stamboli, here we are at an AMA race somewhere in the continental United States, in the middle of O With an attack performance, attack Kawasaki motorcycle, and you're going to give us triple clamps 101 for squids So we have them here on a bike. We'll have to keep it very basic then, very safe. Very basic, they're made out of al Okay, so these, you have a bottom and a top, explain kind of how that works. What we have here is what they call triple clamps, in Europe they call them yolks. But they clamped three different parts of the front end of the motorcycle, there's two fork tubes and also the steering stem that runs through the frame where the front end pivots on. And what our clamps do, different than the stockers, is A, they'll add rigidity as you can see how beefy t And also they'll give you adjustability for an aft. And that adjusts the trail down here, the tire, w They think we're adjusting wheel base, in fact we're adjusting what you call the trail n So you've got a kind of shopping cart when you have the wheel trailing the axle, that's the distance how far back the tire is from the point that turns, we call a point of load. So the point of load goes down through the steering stem and all the way down to the contact point on the bottom, past the contact point, forward of the contact point. And then when you, if you lower the motorcycle you'll see, you'll see that as the tire contacts, see how the bike sways back and forth? Yeah, it's actually pivoting forward of that contact patch. And that's why the bike sways back and forth What we're doing is we'reducing or extending that to give the rider feel or better turning or better stability. So you can adjust all that by just changing t Okay, so let me get t So you're drawing an imaginary line down through here to a point right here and you're saying the contact patch is back here of this imaginary point and that's the trail n That is correct. If you take a straight edge right across t So let'say your point's over here and your contact patch is over here. So you're adjusting that n So as you change your offset to extend your wheelbase forward wheelbase, I'm saying also, but to extend your offset to where it's more offset, you're moving contact patch forward, reducing trail. And making the bike, let'say, more nervous, more flicky, less stability, but easy to fall in and out of corners. And so that is basically the gist of that. And what happens is as you adjust the ride height of the motorcycle to get optim There's three components to trail. One is offset, tire diameter, and also rake angle. Those are the three components. So those components make up the trail n So we adjust one of the components here. And what that does is a lot of people lower or raise their forks. They'll upset the rest of the geometry of the bike, Because as you lower the front, you change the spring arm pivot, your spring arm angle, all kinds of stuff. So t And so as you want to change your effort, you can just change t And so after you get your bike really close and comfortable and you want to play around with somet And you won't affect your grip and all those kinds of t And you buy your aftermarket triple clamps, w Yes, and we sell a variety of different offsets based on what application? Because we make them for all motorcycles, not just Kawasaki's, Honda's, everyt So Okay, so here on the bench, now one quick t So if I get a set of triple clamps, do you have some kind of basic n It depends. I mean different motorcycles take different tall or lankier riders sometimes prefer a less trail because they can muscle the bike. A little shorter riders prefer a little more trail. They carry more corner speed, let'say. So it all depends on the riding style. There's no certain magic. You may end up with one year on a motorcycle that has this trail n Last year we used to run really big trail n This year we're seeming to run much smaller trail n It depends on the tires, the construction and all kinds of different factors. That's why you need adjustability. And you'll find the factory teams are constantly changing. If there was a magic trail n But you'll notice But with our setup here, because we have adjustable inserts, And it makes it very easy to change because you can leave your stem inside the chassis. So you undo the bolts here and you pop out your insert. Let'say there's a four millimeter offset. See how there's a fatter side and a bigger side, a fatter side and a narrower side? You would take something maybe that's even more offset Very narrow. Yes. Versus your, let'say your zero. These are all millimeters. So you would change your offset basically and that would change your trail n You want to change obviously the same top and bottom because the stem doesn't. Ken Zigzag. Okay. So I was going to say, do you, can you mismatch these and put a six and a four and get it to do somet Well, that's a common misconception as well. And people t I mean, wheel base 1400 millimeters and you're only changing one or two millimeters. It's a very small percentage. The very small percentage of trails, usually around a hundred, 105, you're changing it maybe one or two percent. So that's a much bigger change in the point one percent you're going to get the other way. And You change it parallel top and bottom. The rake is done at the steering head, w The Ducati has some Ducati's have, but not all of them. So t Just adjusting the trail itself. And t Yeah. Much We have one's a little bit t It allows us to go a little bit up and down. And based on what we get from feedback customers will design the clamp, thick or thin or Very t So they have a lot of range of adjustment. I think those Peridi The Jordan guys have them. We run them obviously. The n It's a pretty common tool. It's now allowed in our class here that we use for tuning. It's just another tuning tool. But a fairly significant one. Yes, absolutely. The rider feel and feedback and turning is so important on these bike snaps because they're all very good out of the box. To improve on that is you happen to do minor stuff, but it makes major changes on the racetrack. Well, thank you very much. It's been extremely informative and we'll look forward to maybe some more in-depth stuff in the future. I'll have to bring diagrams and charts and posters and stuff. And some case studies where maybe some things happened one way or another and you found, oh wait, when we do this amount of trail it fixed X n Sure, I can probably point out a n Okay? Thanks for now.
