  5. Pirelli Replacement Tires

    in School Questions/General Discussion

    Posted

    These ES's sounds like garbage to me. I'll stick with Honda who clearly believes traction should be managed by the rider, not a computer. To date I don't think they offer any type of TC on any of their bikes... just how it should be. All these computer-aided systems will never be as good at their jobs as a skilled pilot, IMO.

     

    Where's Ducati at in the world championship anyway... oh yeah, trying not to get beat by CRT bikes in one and still *HOPING* for a race win in the other. LOL. IMO prototype racing shows the true engineering ability of a company and Ducati doesn't have it.

     

    Racing grade traction control can help reduce tire wear by as much as 20% ...(ducati DTC is NOT race grade too intrusive for races ; Aprilla RSV4 / Nemesis aftermarket ones are...)

     

    Fuel injected bikes that run with the aid of a computer are ES too ... it depends on how much control you want and how seamless its implemented.

     

     

    IMHO...

    Championships are all or nothing and with only bridgestone as the sole tire provider for motogp.... its as good as dead ; monopoly does not promote competition or breed competetiveness...

    As for any electronic system (ES) , the tire is mapped , hence if you want to optimize the whole bike's ES , you'll have to get a map catered to the tire.

     

    I know BMW, which makes S1000RR's , provide different maps for different approved tires by different manufactureres.

     

    Ducati is now owned by Audi , so you can hope they come out with maps for the Q2's.

     

    But i'd say stick to the stock pirellis first , because im not sure if Ducati has made maps for Q2s yet.

    I just recently had a high speed off myself, so I feel ya.

     

    I would agree that the twist books/dvd are the place to start to get you back in the right mindset. Then make sure your not riding above 80% of your ability at your next track day so you can focus on relearning vs. just scaring yourself over and over. If your like me, visual queues are a direct hard line to the brain and trigger SR the quickest. So I focused on them first. The rest seems to follow in good time as everything mentally "slows" back down. Don't rush it or "try" to hard and BREATH..... Get a good set of earplugs too.

     

    Also, just like looking throw the corner for your RP's, look through the rider ahead of you. Don't let their riding leak into yours.

     

    Next is... "dull the senses" to calm down SR's. How do you do this?

    I would say it either takes alot of practice (especially on the nobs bike/drift/brake rig) or .... pardon me for saying this ... inbuilt talent .

     

    You are your worst enemy.

     

     

    Taking classes ... given that if one can lowside twice in a rce and fix everything up , financially it is really viable.

    Wow, responses have come in quickly... From what little you've mentioned, it sounds more like visual errors (I suspect that's where Hotfoot may be going with her question). If you haven't read Twist of the Wrist II or watched the DVD then now is an excellent time. If you have, then perhaps this is a good time to re-read or again watch the video. When you get back on the bike, I think you can best start by lowering your speeds to where you are very comfortable and not worry about carrying a certain amount of speed. It may feel slow but it'll allow you to put most of your attention on technique.

     

    i second re-reading/ viewing the book/dvd.

    The standard answer is that if you are off the brakes and the suspension is settled, you can not overcome the traction available to the front tire just by steering. Steer it as hard as you can and the front will still not slip. If either end lets go in response to a steering-only input it will be the rear.

     

    I have tested this advice myself and can attest that I have yet to be able to steer the bike hard enough to induce any kind of slide at either end.

     

    But you need to be off the brakes.

     

    not with worn tires/low friction coeffecient surfaces/ cold tires imho.

    Awesome info guys!

     

    ktk_ace - Awesome info on traction control! Those are great articles. Since traction control is slightly different than data acquisition(and more complex), I'm thinking maybe we should start a separate post for it? :)

     

    anthem - Love the videos! That's really neat stuff. I think it could be very useful on the camera bike for any student Level. We like to get students on the camera bike because we can show them EXACTLY what they're doing. Having that data on the screen would give even more info about what is going on.

     

    I have stated that it has simlarities as it taps into the can system ; A dedicated section will be nice thou imho :)

    I use the Aim EVO4. What Aim has done right is that they've built ECU bridges for most major manufacturers bikes. If you tap the Can H/L line, then you can get all the bikes sensors without trying to use an RPM K-line, and putting your own sensors in that are already there. . . AIM has ECU plugs/bridges/instructions for most of those bikes so once you locate the EVo4 logger, you just tap in and you are already on your way with a number of sensors that the bike has (temps, rpm, speed, throttle position, etc). If you want to replace the dash - you can also use the AIM MXL dash units which put the data logger into the dash (or just add a dash lap timer), but I prefer the small EVO4 unit in the tail of my bike. I have a few extra sensors into it, but its not overboard. I can take that data and overlay it onto video as well.

     

    To give you an idea of the Evo4 data feeding the smartycam which I think would be cool for the school to do.

     

    http://www.youtube.com/watch?v=fLmzIRQFe1w&list=PLQRA6OR-5SCXigl060CU-Qb-KHG-dEcR1&index=5

     

     

    And yes, I agree that you can detect a lot of this from sound (rpm), but its a lot easier with actual data being shown (speed, rpm, brake pressure, throttle position, etc). And it puts the school into another "cool" category which most people don't have access to. But then again, it might encourage people to do the camera bike more which I'm, not sure would be the CSS goal ????

     

     

    Im thinking that such a setup is useful only at level 4 as the level of customization tailored to each individual will show using both the camera and onboard data logging before and after improvements/coaching ....

     

    And imho its quite costy now, the financial barrier is no joke now.... maybe when such systems start to become abundant and cheaper?

    A bunch of links that are a good read on how the TC and ESP systems read and react :

    personal rant:

     

    We live in exciting times, Being able to see and use years and even decades old BANNED F1 technology finally trickling down to consumer vehicles .

     

    you can see whats banned here: http://www.f1fanatic...ures/banned/ ( theres a page 2! )

     

    Fortunately for me as a teenager (what? 15 years ago?) , I was able to get a glimpse of it thru the imagination of a future where all the real world banned stuff isnt banned (eg parallel fictional world )

    by a company called sunrise and its re-imagination (with some trinklets thrown in for good entertainment measure) of the future thru an anime called Future GPX Cyber Formula .

    In that fictional future time line (and this video

    ) you can actually see (in a fictional way) the combination of said currently F1 BANNED technologies such as

     

    Ground effect

    Active suspension (S1000RR HP4 YAY!)

    Traction control

    X-wings

    Turbos

    Four wheel steering

    Slicks

    Gas turbine engines

    Six-wheelers

    Rocket fuel

    Flexi-wings (458 Italia)

    Brabham-Alfa Romeo BT46B ‘Fan Car’

     

    I sure hope to live in such a future given all the technology is already available a few years or even decades ago... And IMHO thats why I dont watch F1 anymore; its boring and nerfed to me

    I only heard that the S1000RR HP4 usues a centralized CAN BUS system for all the sensors and controls ; powercommanders/ bazzaz stuff apparently tap into this system too

     

    http://en.wikipedia.org/wiki/CAN_bus

     

    I personally diverge more into how the TC and ESP systems are implemented in different brands; seems that the Europe approach(BMW /APRILIA) and Japanese(KAWASAKI/YAMAHA) approach are pretty different

  25. Nasty Target Fixation

    in Cornering and Techniques

    Posted

    You can see the rider running out to the white line and the question I have is did he target fix on them or was just going too quick for his personal skill set (sic) and just ran wide inadvertantly cutting these unfortunate riders down.

     

    Well, clearly he WAS exceeding his skill level, as proven by the fact that he HIT something!! However, the rider does not appear to be going exceptionally fast, and he is certainly not leaned way over trying desparely to tighten his turn - in fact he appears to stand the bike UP, instead of trying to turn it more - so I don't really think speed was the primary problem. It looks more like he panicked, staring straight at the thing he didn't want to hit - and simply did not know what to do, so his Survival Reactions took over. Some of the classic SR responses in Twist II include:

    Roll off the gas

    Tighten on the bars

    Fixed attention (on something)

    Steering in the direction of the fixed attention

    No steering or ineffective steering

    Braking errors (over or under braking)

     

    If the rider did not know WHAT to do, he probably panicked, grabbed a handful of front brake (which would make the bike run wide), stiffened his arms (also makes the bike run wide) and never attempted to steer away from the bicyclist at all - all classic SR reactions.

     

    They should put up a warning on Mulholland that all riders are advised to attend at least one day of California Superbike School before attempting to ride that road. :)

     

    That is a brillant idea imho.
