    Off camber corners

    I would expect it to be more than just the angle between the road surface and machine/man that comes into play since you are now also facing gravity in a negative manner; it's like standing on a slope. Hence you cannot just use your knee as a guide to how far you can safely lean. Perhaps it's a case of going faster until you crash and then back off a little πŸ˜„ Personally, I treat them as I would a surface with less grip, but I only ride on the road. On a track, if you want to find the limit, I would suggest being smooth and add a little bit of speed while feeling for the tyres starting to slide. It may also be wise to square the corner off a little more than typical in order to keep apex speed lower and also the period of maximum lean shorter. All that said, you really should not listen to me because I do not actually have a clue πŸ˜”
  5. I am looking for a new helmet, but it has proven very difficult to find one that fits perfectly. This is what I have learned, both recently and over decades: SHOEI - pure pain. They are too narrow at the sides of the top of my head. I cannot even keep on on for 5 seconds, not even one that's too large. ARAI - acceptable, but tend to hurt around the temples if tight enough. Loud. NOLAN - not exactly luxurious. Loud. But OK to wear. Tend to sit low over the brows. AGV - Comfy enough, but will drop over the brow when correctly sized otherwise. Not great for wearing glasses, which I must wear. SHARK - Great for glasses, comfy if I use one size too large, but like Shoei - to a much, much lesser degree - hurt on the sides of the top of my head when the correct size is used. SCHUBERT - feels too narrow on top and too wide at the bottom. Not comfy for me, but not painful, either. HJC - interior feels hard, and like Schubert a bit wide at the bottom and narrow on top, but less pronounced. CABERG - impossible to wear glasses, interior feels a little hard and seems like it will be loud because there is too much room around the ears and the helmet is a little wide at the bottom. Most helmets are too tight around my cheeks, and tend to bite myself. Literally. Sizes listed also vary a lot. I need a Small Shark helmet, a Medium CABERG and a MediumLarge AGV, for instance. But that is irrelevant as long as I can try it on for size. Based upon this information, can you recommend a brand of helmet I should try to search out? A helmet that is, I presume, for a rather round scull seen from the top, not egg shaped.
  6. Finally found an almost perfect helmet - for me. I ended up with an Arai Axces 3, the cheapest in the shop. If you can call a USD500 helmet cheap. Pinlock not included, another 40 bucks. Unfortunately the cheap one, I may add; I wanted a higher level helmet with a sun visor. But those had a slightly different shape that was narrower. My head is probably of a rather unusual shape, because even the model I got should ideally have been 1/4 inch wider and a 1/4 inch shorter - and it is the widest and shortest helmet I have ever tried. Anyway, I bought one size above ideal for this very reason. The helmet is still very snug, but easier to put on and remove than anything I've owned or tried before. Also a plus is that while the head moves with the helmet, I do not bite my cheeks when I close my jaws. With the perfect size, M (57 cm or 22.45 in) the helmet was just tight enough on the sides that I knew it would feel uncomfortable after an hour or two. The L (59 cm or 23.23 in) just sits snugly with no pressure, but if I pull the helmet firmly forward, the sales-woman could get 4 tiny fingers between my forehead and the liner. However, since the helmet didn't drop down over my brows, not even when pulling on the chin bar, the sales-woman agreed to sell it to me, although she would have preferred me to go for the smaller version. I told her I would be more likely to crash if I was in pain, to which she agreed, and also since the helmet sat firmly in all directions it was deemed safe. The Arais, all of them, also work splendidly with glasses. I also tried a Shubert, and while not as painful as a Shoei, it felt "bony" like a Shoei. And the ear cavities were placed too low for my ears. So what I have learned is that Arai helmets fit me the best, with AGV helmets a clear second. And that Shoeis are still the worst for me, both in fit and also comfort; the interior feels harsh to me. Also, there are differences between one Arai to the next, and that goes for every helmet brand out there. Take your time and you should eventually find just the helmet your head need. BTW, the costliest Arai helmet on offer was the RX7V Carbon with a sticker price of NOK 31.999, or 3800 American dollars 😲
  7. Not detailed, but I still found it very interesting. May also explain why succeeding in one class doesn't automatically guarantee success in the other. https://www.crash.net/wsbk/news/911327/1/debutant-bautista-riding-ducati-world-superbike-250cc
  8. It's what I've been doing instinctively since I first began riding in 1980, and I find it difficult to push - or pull - only. I believe I did it like that from day one because it must have felt balanced when riding ultra-light 100cc streetbikes of the day; with no place to really anchor oneself against the forces going through the handlebars, pushing and pulling - albeit gentle - would ensure a fair balance of forces reaching the body.
  9. Original topic altered after I was made aware that it may not be PC. On another note, there will be new FIM regulations for helmets from 2019: HelmetsThe Commission approved the new FIM helmet standard established by the FIM for all circuit racing disciplines. This means that there will now be a single, enhanced standard for helmets, replacing the various international standards used before (ECE, Snell and JIS). Helmet homologation tests are ongoing with some manufacturers having already concluded the tests and some planned within the next weeks. It is the intention of the FIM to publish by the Valencia GP a list of the helmets manufacturers that have been approved through the FIM Racing Homologation Programme and of those which are working to achieve this.

    Center of gravity

    If you read German, or are willing to read google-ish https://www.motorradonline.de/test/handlingtest-konzeptvergleich.318659.html https://www.motorradonline.de/fahrwerk/fahrwerksspezial-teil-4-balance.403707.html https://www.motorradonline.de/schraubertipps/masse-gewicht-schwerpunkt.407803.html https://www.motorradonline.de/werkstatt/technik-fahrdynamiksicherheit.222272.html A bit surprising to me is that by lowering the CoG from 800 mm to 500 mm, using 160mm wide tyres on average (120 front and 200 rear), to corner at a speed that demand 30 degree lean with the taller CoG would require only an additional 3 degrees of lean, up to 33 degrees.

    Mid-Corner Countersteering

    I cannot really debate this, by my personal experience indicate that my line will tighten with a dab on the rear brake and widen by adding throttle. Whether this is due to other influences that comes as a result of my actions, I cannot tell, but the net effect for me is that a bit of rear brake does tighten my line. A bit like does it matter if you get well through placebo or medication, as long as you get well? ? Personally, I have never had any reserve against adding more lean mid-corner when required, even quite rapid changes. And I've never had a slide as a result, either. I am far more concerned about turning quickly when upright, probably because I've done so under heavy braking and possibly less than perfect traction conditions and experienced a few slides. I realize that my actions are not rational, that turning in should give more grip than turning in more at 35 degrees of lean, but something has become wired wrongly in my brain that is difficult to sort ?
  12. That filled in information that was missing for me when trying to understand why I had so much difficulty adapting to the early braking-before-turning way of riding after always trail-braking more or less to the apex. In the end, I wound up with a compromise just the way you described it above, but thought it was just me not being able to properly adapt to the "proper way" of turning in. Now I feel much better - thanks ☺️
  13. Sometimes, a rider is a perfect match for a bike, like Stoner on the Ducati. Doesn't mean the bike is particularly good, but that the combination is. That seems to be the case with the current Kawasaki, where Rea perhaps is able to use the extra torque that comes with a lower rev limit to good effect, whereas the others may struggle to get the bike to hook up and get drive. Just speculating, but there obviously he has found strengths with the bike others cannot utilize. You see the same thing with Honda in MotoGP, where only MM is consistently winning and taking podiums; it could be that that bike also is very difficult to master, but if you have that extra bit of talent - natural or learned - it may be possible to explore terrain restricted to "lesser" individuals.
  14. Several riders have to titles on the trot, but I believe Rea is the only to take 3 and now 4. He really is dominant in the series, despite having to ride an emasculated bike, enforced on him in an attempt to slow him down. He is so far ahead of the other Kawasaki riders most of the time, I have wondered if Kawasaki give them less competitive material to prevent further engine restrictions for the team. Didn't he also set a new points record for a season this year? And winning the final 12 races of the season is also darn impressive. I still doubt he has what it takes to beat Marquez, Lorenzo, Dovi and Rossi, though.
  15. You can even ride crossed-up https://www.youtube.com/watch?v=dEYEn_fpv-4
  16. In 1984, Kevin Cameron wrote an article in Cycle magazine about active suspension, how Lotus was testing real world models. Cameron considered it the future. Not the least because the systems we use today are quite inferior, even the suspension used in MotoGP. Simply put they cannot follow the road and they come with a harshness as well as harmonics detriment to handling, grip and stability. He also expected the active suspension to lower the bike under acceleration and braking and raising it for cornering clearance and bigger bumps. Not only for racing, but for everyday riding. Cameron also expected to see power steering and stabilizing systems that allowed radical steering geometries far beyond what a human can control by him/her self. Like fighter airplanes that would shake apart in seconds if left alone to be controlled by a human with no computer assistance. He also wrote about putting multiple 'puters in the bikes to make sure that if one went down, there would still be several working - the bad one would simply be shut off together with an error message, but without disturbing performance. Furthermore, he expected the fork to be replaced by better systems (which only BMW have tried on a large scale) and traction control more sophisticated than even the best we see today. Not everything happens as quickly as we (some) anticipate.
  17. To those who have ridden a lot of bikes over the years - if you took the best sport motorcycles from yesteryear and put them up against the current bikes of the same size but less sporty, fitted them with the same tires (where possible) and sent them around a race track, which would win? I'm asking because people have told me for quite some time that modern bikes, even budget bikes, are so much better than the stuff just a decade old. In my experience, my FZ07 has suspension no better than what many bikes could offer in the 80s, so I do not buy this. However, I could very well be wrong. So what if you teamed up something like these pairs, do you reckon the latest would beat the oldest every time? Or would it be the older sport bikes taking the honour? 1992 CBR900RR vs 2017 CB1000R 1993 GSX-R750 vs 2017 GSX750S 1994 ZX-9R vs 2018 Z900 1994 FZR600 vs 2017 FZ6R 1994 916 vs 2017 Multistrada 950
  18. This is pretty funny
  19. I doubt Rea would ever become MotoGP champ. Spies, Toseland, Hodgson, Bayliss - many a splendid rider has tried, but the level at the top of MotoGP does seem to be a bit above the peak of any other class. That doesn't mean I think little of Rea; I cheer him on and love to see him dominate WSBK. As to the Repsol ride, that has gone to Lorenzo.

    Thanks for asking, but not really. There are some tests between older and newer sportbikes, but what I really would want to know is whether an old sportbike from the 1990s is still quicker around a race track than a current standard style bike of similar capacity and power. Or if even a Plain Jane bike of today is stopping, turning and cornering better than a race rep dating back 25 years. I know, for instance, that Cycle World found the ZZR1100/ZX-11 to be about 4 seconds slower around a track than the FZR1000 back in the early 90s. But I do not know how that ZZR would stack up against a 2018 Triumph Sprint GT, for instance, provided same tyres for both. Here is one interesting comparison, but still sport vs sport - sorry if the video is a repetition from earlier.

  22. My grandfather saved his life because he didn't wear a seat belt - his very old Mercedes (1957) was reduced to almost nothing, but there was still a bit of space down at the passenger foot-well. That's also where he ended up. But although no belt may be the better option in 10 or even 20% of the incidents, that leaves 80 or 90% where they turn out to be a benefit. So I wear mine, but I am not good at removing my thick winter clothes or pull the belt really tight - both important to get the most out of the security from the belt. Just an inch of slack on the lap strap can cause massive internal injuries, I'm led to believe.
  23. - then we may have to re-evaluate the widespread notion that the modern riding style began with Kenny Roberts Sr. https://silodrome.com/john-surtees-vincent-knee-down/
  24. Center stand, most likely. Used to sit along the swingarm.
