There was also the fact that without computers to design the bikes, you could repair the thing with tin cans and baling wire and be fine.

When I go to my local dealer for parts they still look stuff like chain and sprockets and brake pads up in big loving books so I'd imagine there was just a lot of catalogs and hardcopy parts fiches and phone calls to mail order places.

Ive got a twofer for ya. I started riding in 88, on a 60-something Arctic cat mini bike. No dealer knew what they were, or supported them. It was all duct tape and bailing wire fixes for that bike. I then graduated to a Kawi kdx 80, which was at least supported by the local Kawi dealer (40 mins away). So to answer your question, you trusted that the dealer both knew what they were talking about, and that they could find and get the right parts. You either knew how to fix it yourself, or you took the dealer at their word.

Sure but also now we have things like shapeways that will print you a 60/40 steel/brass part for relatively cheap. I'm thinking because I'm gonna have to custom fit the reluctor rings for the ABS setup, that might be a cheap and easy way to go (assuming, of course, that it's strong enough...I've gotta ask my machinist friends about that).

Well, I'm glad I was wrong about that. I don't relish the idea of running around from stall to stall, asking old men in aprons if they have an ignition control module for a '79 as they look at me over their glasses, but it's interesting to hear about it.

The main problem with any of those alternative fork systems is the fastest riders are used to conventional forks. The 'feel' is different, and as a result they don't trust the front end feel as much, and aren't able to run the front tire to the limits of grip. I think it would be very interesting to see if this actually makes it to Moto2, but if it does, it will most likely be a failure.

As it says in the article, the system apparently keeps the 'feel' you get from a conventional fork and doesn't have the slop that a linked hub-steering system usually would. If it works as advertised and works fine in carbon fiber, I can see it gaining traction. Going straight to moto2 might be a bit of a tall order, but we'll see.

Depends on their rider really. -1s per corner won't look all that spectacular if his conventional times are dogshit Either way, at least we won't have to wait more than half a year to find out, if their plans hold together.

Rev. Dr. Moses P. Lester posted:I think everything other than telescopics are heavier/bulkier too. That matters a lot in racing obviously. Which is why people are still looking for better alternative than telecopic forks. Telescopic forks are pretty heavy things themselves and place a lot of their mass pretty far from the steering pivot axis, from the top triple all the way to the axle. Reducing the moment of inertia by centralizing steering mass mitigates tendency to wobble.

The 1 second a corner faster number is essentially meaningless, as if that were the case a moto2 bike with that front end would end up faster than most MotoGP bikes. But it's a cool concept and I hope it takes off, I like FFE bikes.

A couple noob questions: Why is it advised to increase throttle while going through a curve? What do you do if you really need to sneeze? I am mildly terrified when I have to do that in a car.
|
# ? Mar 25, 2016 05:31 |
|
If I have to sneeze I just sneeze. Get my hand up to cover it if I can do I don't coat the inside of my helmet. As you're coming out of a curve giving it throttle will stabilize things and begin to stand the bike up. Gradually feed on throttle when you get past the apex. You probably do this naturally anyway.

Your tires are different sizes and have different contact patches accordingly. Getting to maintenance throttle (where the bike is neither accelerating nor decelerating but holding speed) allows you to achieve greater levels of lean (because you won't override the front tire) and ground clearance (because being on the gas lifts the bike off the ground due to a combination of weight transfer and chain forces pulling the swingarm towards the ground). You should get to maintenance throttle as soon as reasonable (i.e., once you know you're going to commit to a certain level of lean for a corner), and then as you remove lean angle on corner exit, add throttle. A properly set up bike will not change lean angle on the throttle or the brakes - most of the time that behavior exists because the rider expects the bike to do so and so it follows where the rider looks/expects it to go. There's some general guidance around this for street riding - don't get on maintenance throttle until the vanishing point is opening up or you're comfortable that you're not going to need to slow more, as transitioning from maintenance throttle to off the throttle requires more traction from the front tire as weight transfers forward and can unload the back tire to the point it starts to come around on you. (Note: The vanishing point is watching if the centerline and fog line are getting closer together, stays g the same distance apart, or getting farther apart at the farthest point you can see in the corner. This is 100% of how you ride fast up an unfamiliar road, safely) For examples of the 3 corner types: Decreasing radius - vanishing point is closing up. You should be off the throttle, slowing down until you're comfortable you're going slow enough to make the corner. At that point, the corner effectively becomes a: Constant radius - vanishing point is holding steady. As you leaned into the corner, you can pick up maintenance throttle smoothly, and apply light pressure to the inside bar until your lean angle is set to the final angle you want to make the corner. Opening radius - the vanishing point is expanding. You've already hit the highest point of lean very early in the corner, so this is standing the bike up and adding throttle to taste on corner exit. Other hot tips for new riders: relax your outside arm and steer with only your inside. You're likely to be resisting with your outside arm when you give a steering input. Grip the bars like you have rice paper between you and the grips. Tearing it means you've failed. You should only grip the bars hard enough to overcome the spring tension on the throttle, and at any point but during active clutch usage or steering input, should be able to remove your left hand from the bar. To do this you'll need to lock to the bike with your legs and hold yourself up with your core. Practice smooth engagement of all controls at all times, especially during emergency braking practice. Smooth gives the bike a chance to find traction and gives you the chance to stop rolling on the gas if you start sliding or release the brake if it locks. I think those are the big hot tips I'd give most new riders.

pokie posted:What do you do if you really need to sneeze? I am mildly terrified when I have to do that in a car. Reduce speed, try to take a line that won't have anything in it until your eyes work again. If the road environment is changing fast enough/has a lot of hazards and you think you might be incapacitated for a while (eg sneezing fit), pull over. On the motorway it's not usually that big of a deal. All those factoids about how far you go with your eyes shut sound scary, but the road environment out there is generally much more sedate than city roads (ie there's fewer hazards, and the ones there are tend to develop more slowly), so just mind your distance to the vehicle in front.

What books do I need to purchase for more of this kind of thing? As a newbie motorcyclist, I found the book Proficient Motorcycling by David L. Hough incredibly helpful. http://smile.amazon.com/Proficient-Motorcycling-Ultimate-Guide-Riding/dp/1620081199/ref=dp_ob_image_bk It really helped me visualize motorcycle dynamics in a non-intimidating way. It also took motorcycle physics and applied them to the street/commuting world, which was very nice as somebody that won't be hitting the track for a while yet. It was largely geared towards riding your motorcycle in a safe way in the real world, which is what I was looking for. Otherwise, Twist of the Wrist and TotW2 have both been recommended, but they really are geared more towards the track/fast riding. Z3n and a few others have recommended more book than I can remember, and you should pretty much read them all. Helps to scratch the motorcycling itch during a rainy day (or long winter).
