  1. I can only link to the teaser, but I am a paying member and have watched the full video. But how much importance does the profile shape, carcass construction, height and width of a tire matter in your experience? Because a 120/70-17 tire can vary greatly in size, profile and construction between models, would/do you adjust your bike to accommodate every time you fit different tires?
  2. If I understand you correctly, Gianco, you must continue to countersteer all around every corner, otherwise the bike will want to straighten up. Is that correct? My NT650V was like that with a Bridgestone BT30F on the front, demanding a very noticeable constant push on the inside handlebar grip. When I replaced it with a Maxxis M6029 Supermaxx, the bike actually went in the other direction, now demanding a miniscule pressure on the other end of the handlebar, otherwise the bike would slowly tighten its line. I have had similar, although not quite as dramatic, differences on other bik
  3. The REAL meaning of the Haynes instructions Haynes: Rotate anticlockwise. Translation: Clamp with molegrips then beat repeatedly with hammer anticlockwise. You do know which way is anticlockwise, don't you? Haynes: Should remove easily. Translation: Will be corroded into place ... clamp with adjustable spanner then beat repeatedly with a hammer. Haynes: This is a snug fit. Translation: You will skin your knuckles! ... Clamp with adjustable spanner then beat repeatedly with hammer. Haynes: This is a tight fit.

  4. I don't know, it was all a blur to me 😄
  5. I guess people in India are used to close encounters from daily traffic. Amateur racing between people without India experience
  6. I think you are correct that he didn't care. Not just with racing. A superior talent with a very troubled nature. Still troubled, not so sure about the amount of talent remaining.
  7. Sometimes, it is best to hurry slowly in order to reach the destination the quickest. Take care of your body and let it heal at its own rate, pushing it towards, but never beyond the limits it sets 😉 Hope you get back to full health!
  8. This is perhaps the nicest motorcycle road in the world, I don't think it could be designed any better. I'd love to see a hill-climb race being held there 👍
  9. You probably should watch the video 😉 On braking, he mentioned that some riders will lean the bike a bit when braking in order to get more deformation of the tire and hence more grip for retardation.
  10. I have no clue if this is spot on or not, but I presume the instructors know
  11. Superb observation - it's been staring us all in the face, but only you noticed it 👌
  12. I am no expert in any way on this, but I presume it is about awareness (where are you placed) and confidence (rely on your knowledge about where you are). Some are better at knowing where in space they are situated than others. Personally, I am hopeless, which is why I constantly bump into things. So I need some margins, likely more than you, to feel somewhat in control. Here are some pictures for inspiration about using all the available space, and then some, showing what is possible:
  13. This video show partly what I feel is happening with my old 650 (I have just bought a CBF1000, though I have not picked it up yet) - there appears to be too much lean for the speed, although not as dramatic as I - and my observing son - feel it is on my Deauville 650.

    KTM

    Been a very nice season so far for those with no particular hero, with more riders and brands winning or entering the podium than usual. It has also proven that nobody can currently match the speed of MM. It would be cool if a Suzuki take the title, it would be cool if a non-factory bike take the title, it would be cool if a French took the title, and it would be cool if Dovi finally got the title. In other words, l would be happy with either of the currently top six ending up as champion.
  15. Well, I am probably guilty of everything you pointed out, Jaybird 😄 However, when it comes to lowering and/or lengthening a vehicle for better stopping or acceleration, it is a result of the vehicle's ability to resist flopping over forwards or backwards. Although only if you already slowed or accelerated hard enough for that to be an issue, of course. This partly explains it https://www.physio-pedia.com/Centre_of_Gravity#:~:text=Stability and the Centre of Gravity,-The direction of&text=When the line of gravity,is said to be stable. Sorry if I just dug myself a bigger grave h
  16. If you lower the CoG, less weight will be shifted forward and you can stop harder before you do a stoppie. Which is also why a long and low bike can stop (and accelerate) harder than a tall and short one. However, I am not certain that the fork will compress more doing a stoppie while sitting upright with stiff arms, than doing a stoppie laying low with the resulting lower CoG. Since you can now slow down harder, would not even more force be fed into the suspension? But for the same rate of retardation, you probably will end up with slightly less compression of the fork laying down. Howev

    Jorge vs Doohan

    Noticed Lorenzo was hopelessly slower than everybody else at the recent test, more than 3 seconds off the Aprilias. The explaination was that he is unfit and have not ridden since January. I remember Doohan in 1999 at PI. He could not walk properly and had to be lifted onto the bike, and his hand did not have the power to pull the clutch. The bike had a totally new powerband due to Criville wanting top end over driveability. Doohan dis not know the tires, the setup or anything else as the plan was to just wave to the crowd. As I remember it, he waved most of the first lap, found it f
  18. Would that not depend on how much power is fed in and how much the bike is leaned over at the time of throttle application, plus how much more lean is needed? But it does seem like a recipe for loss of traction.
  19. Could be l used to be more abrupt, and l definitely was braking late on purpose, so that could well be the issue. On the Honda, l now brake less hard and ease off them, then going directly to rolling on the throttle. I am beginning to get to grips with setting the entry speed early, but with 40 years of braking deep it is what I know. At the age of 16, riding a CB100 limited to 50 mph, l would brake at the latest moment possible as often as l could, and l gave myself a maximum of one yard error - if l stopped sooner or, much worse, overshot, it wad considered a fail. I did this on all sor
  20. No, meaning I explained myself poorly. All previous bikes I can recall having attempted early throttle application with would fight me and go wide, usually enough to make me get off the throttle again for a moment. That was the case with the NT650V until l replaced the tires recently. The XVS is a bike l rode gently home on 20 year old tires in November and have restored since. It is fitted with new diagonal Pirelli touring tires. It did not react well to my normal riding habits, which is how I subsequently ended up going in slower and exiting faster, and that the bike acted absolute
  21. Something happened recently when I fitted new tires on my NT650V, when I suddenly found I could apply throttle very early in a corner - slow or fastish - without the bike wanting to noticeably widen its trajectory. And now I found the same thing with my other bike (although it does not belong in a sporty setting), an XVS650: I can roll on the throttle fully (it is, however, a slow bike) the instant I am at full lean and it will not deviate from its chosen line one inch, nor does it take any effort to retain the trajectory; I remain relaxed at the bars. Now I wonder if I have changed somet
  22. Thanks, Jaybird, good video. This is absolutely correct, and very well explained in a simple manner. It is not as dramatic as the video suggest - I think it is about 4 degrees difference between a 130 and a 240 mm wide rear tire, all things else being equal - but it is significant. Not the primary reason on my bike as it has a 120/70 front and a 150/70 rear tire.
