    I was doing #4 tankslapper, relaxed leaning forward position on bike - it really helped

    Sometimes, despite your best efforts, an off can happen. Even the best, most cautious riders come off sometimes. The thing then, as you said at the beginning of the thread, is to analyse what went wrong and try to see if there are any lessons in it for next time. Hitting wet tar bleed is going to be hard for anyone to recover from doing open road speeds, but now you've learnt to identify what to look out for, and with smart road positioning, you can often avoid places where the tar bleed has happened. But there are no guarantees in life, except taxes and death, and those are both whole other thread topics...

    That Roadcraft Nottingham video linked somewhere up nearer the start of the thread had some good pointers about road positioning, and how position "4" (in a 1 to 5 position method), which would be the cars' right wheel track, is not always automatically the best position on the road, depending on circumstances. When the tar melts in the heat of summer, the tyres of cars running over the melted tar in positions 2 and 4 would "steamroll" it smooth and indent that portion of the road somewhat, resulting in a much more slippery surface when wet due to the smoother surface and the fact that water is more likely to pool there. In those cases, position 3, the "sump position" or centre of the road, would have rougher, better grip road surface, higher level meaning water would run off quicker, and the concern of oil isn't a great danger on open road as modern cars don't leak much oil and they'd all be doing open road speeds at a place like that so minimal oil or other debris would be dropped there. But it depends on the age of the road surface and a bunch of other considerations.

    Then you also have areas of open road down a fast hill, where trucks all use their engine braking, causing lots of little judders in the road surface, which if you happen to be doing a particular speed, can be just the right harmonic to set off a tank slapper.

    Yeh... ill get them to stop showing off with all those pointless stoppies under brakes to eh. Having the back wheel off the ground must just un-neccessary danger right

    yes something's we will never know no matter how much we try.
    so what have we learnt so far.
    some accidents are avoidable, some are unavoidable, some we can learn from, most we cannot.

    and some people will never learn.

    thanks Samgab - After my off, I now vary my road position just like your post above and RoadCraft Nottingham
    funnily it was my change from my first time round that corner earlier in the week (it was raining then) I cut the corner completely, the second time I rode the outside wheel track - like I was taught to 'see more' around the corner - this was where the tar bleed was....

    I am always open to listen and learning from others. But I learn most from my own mistakes.

Or as the guy in the video said you may be riding a bike with a poor suspension set up or modification so maybe get your bike checked if you have bought it second hand. Maybe there could be an issue with some brand new bikes being more prone to it than others and it's quite understandable that magazine testers would not be keen to test them for their tank slap potential. I guess I have been very lucky with the bikes I have bought over the years.
    Fwiw. I was referring to your holding the bars tightly.... im reasonably sure youll have most of your side of the fence to yourself on that argument. Thats all!

    This is worth a mental note. I'd love to. I won't, however, be using my own bike. I have no experience of this type of riding so I would want to eliminate the fear of dropping it. After a few laps (or more likely visits) I'm sure I would though. Once I'd gained a bit of confidence.

    I have the same problem with gravel. I have an irrational fear of dropping the bike so I don't do a lot of it (I don't shy away if it presents itself though and do sometimes go looking for it).

    Cheating if that's all I did, yes. However, that is definitely the place to start.

    I have yet to do a wheelie or stoppie, my bike is on its centrestand

    I will admit to have learnt something about others accidents and mostly my own on this thread.

    and I dont understand what meh! is

    If it happens that you do find yourself getting into a slide:



    -Source: Rideapart
    Hot day, sudden downpour, track drying so go out for my first sighting lap. Exited a corner and straightened but hit a puddle and back wheel slid out...I left throttle as was and was happy for bike to right itself, but; the wheel spin had lifted the engine revs into peak torque and as it exited the wet patch got lots of grip and torque. I found myself airborne, holding the handlebars and looking, between the taped headlight and the front wheel, at the radiator.

    What did I learn? my judo rolls work coming down head first onto a track at speed; going like a starfish on the tarmac to slow yourself in the wet only works if your bike is not upside down and speeding towards you; race tape and a ducati clip on will fix a Kawasaki and allow you to play on the track for 2 more days and ride 1600km home; a broken rib means it's harder to hang off the bike and you realise just how far the bike will actually lean.

    What would have happened if you used the clutch when you realised what was going to happen?

    Mate, I have spent far too many years not doing anything except work, it's been worth it but I have missed stuff, I don't care if I look stupid, but if you don't know ask. Look at the SASS site I have asked a lot of questions there. I maybe restarting my riding because I feel I didn't do it right the first time and get the bike setup properly. I haven't been comfortable with how I control the bike. As I want to progress to a larger bike I want to get the basics correct first.

    i know I will get shit on KB, I can give it as well, but that's the only way I will get answers by asking. There is a lot of knowledge here, just sometimes you can get it.
