    hi internet webby thing people guys.
    has any one stuck decent crash bugs on the 3ln before, where'd you get them from (did you make them) and where's the best place to mount them ensuring nothing touches the ground in a crash? im sick of cleaning up damage to my bikes this is the third crash Ive had n its getting expensive when it doesn't have to be. Ive already ordered fold back mirrors so the originals will stop bending the crap out of my front sub frame.

    you won't believe what happened to my poor bike. was trying out some led wheel lights you screw on your wheel valve n they light up and do pretty things when your wheel goes round. had all my riding gear on except my leather jacket (which im kinda glad of now) and these little things weren't working so i pulled back in, took my gloves off and fiddled round with them cos my gloves were to clumsy. jumped back on and did one last run down the road cos i didn't realize the time i was almost late for work. my mate gave me the thumbs up as i went past at about 50km/h (to say they were finally working sweet) so i braked quite firmly in a straight line with my front brake but nothing my tyres couldn't handle (the lights are illegal so wanted to get back in the drive before a cop came round the corner) when all of a sudden for no apparent reason my front tyre just locked up and collapsed out from under me and i went over on the left side sliding down the road for bout 12 meters. scratched up my hands, forearms and left shoulder while sliding (o joy) quickly got up first things first look round to see who saw that <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) --> don't we all. Then picked the bike up and parked it on the side of the road almost dropping it on the other side cos i slipped on the oil spilling out (id shredded a hole in a cover but it was due for an oil change anyway) and went storming off back down the street like a pissed of SS trooper cos i knew i wasn't to blame. Amazingly i was oblivious to all the blood running of my arms but there was something weird bout this crash i could feel it in my bones and sure enough exactly where i went down would you have guessed it (an act of God is all i can put it down to) lying innocently in the gutter was a flattened scratched up long handled teaspoon!!
    the mighty Yamaha brought down by a tiny little cutlery utensil. the frigen road was four lanes wide and i just had to run over the exact sport where it was lying didn't i. the bikes not insured so now i need left wing mirror left indicator and new left body fairing. one funny thing that did come out of it, the wounds on my arms have scabbed over now so my arms are roughly stuck in the position that you're on the motorbike in cos if i bend to far in either direction it cracks them open again.

    Your glad you were not wearing your leather jacket? I would much prefer some marks on my jacket than on my arms - thats why I bought mine.
    You can get oggie knobs and fit them on the engine mount bolts - you will have to cut a hole in your side panels.

    well the jacket was brand shiny new so because it was a slowish crash i didnt mind cos my skin will heal back free of charge. have you got some on your bike if so where did you mount them

    the fzr fairing sucks. lol. its so badly shaped and cheaply made. my bike fell off the stand in the garage once and it cracked both sides of the fairing!
    god bless ducktape.

    lol, that sounds pretty unlucky bro, poor fizzer <!-- s:( --><img src="{SMILIES_PATH}/icon_sad.gif" alt=":(" title="Sad" /><!-- s:( --> im dreading something stupid like that happens once my bikes been fully rebuilt. But seriously, front break should rarely be used, if anything, i use the back and dropping gears for braking (much easier to control once it locks up)

    Ive seen one too many people panic on front brakes an end up flipping the bike, you can hit the back brake as hard as you like and maintain control, hit that front brake as hard as you can and seeya later! <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->

    Sucks though, hope you get everything back togethor sooner then later =)

    You have got to be kidding me. Really and truly, how many people have you seen go over the bars?!

    On a sport bike, even on the street, the front is the main braking system. Do you know why? Something about the ability to unweight the rear - completely under control - leaving the back with no traction to slow you down.

    Know what happens when you grab a handful of front in poor traction situations? You tuck the front, and low-side. Know what happens when you mash the rear under poor traction? You skid the rear, get sideways, highside and die. No thanks.

    You know what else happens when you approach a corner and use only the rear brake and engine braking? Your front tire is cold, and gives up too soon. Front braking warms the front tire, improving front traction for cornering!

    Using the back as well as the front helps to settle and stabilise the bike, improving both braking for a corner as well as coming to a full stop. Using JUST the rear is asking to pile into the ass-end of a transport truck, or the side of a turning minivan.

    You serious? Ever heard of weight transfer? Max braking on your back wheel is around 10-20% of what you can get out of the front wheel. I pretty much never use my back brake, and every motorbike instructor I've ever listened to said only use front brake on a sportsbike (maybe a little back brake in an emergency to stop you faster).

    hey dontz thanks ever so much for that really interesting information you gave. makes me appreciate these sites so much more
    Ive never thought of it that way. Ive always thought lateral and driving forces (the latter for the back wheel only) through a corner do all the tyre warming so if you wanted to really heat your tyres good and proper you'd have to accelerate harder and progressively get faster round corners. Forgot about braking forces heating the respective tyres also. As for which forces (driving , lateral and braking) do the most amount of the heating well i guess that's completely dependent on how you ride.

    i have seen people go over the bars a few times before but that was mostly affected due to things like bike design (eg not being use to a high seat encouraging a very forward body positioning there for weight biased forward encouraging the back wheel to lift off earlier) also not pushing your weight rearwards while emergency braking to also help keep the rear down, and of course the old enemy inexperience ! never having been in that situation before, panicking and grabbing a massive hand full of brake to fast then when the wheel comes up not releasing in time.

    PLEASE correct me if im wrong dontz i must respectfully disagree with your statement
    i know of 2 reasons for high siding in a corner. 1 to much power causing the rear tyre to slip and step out, rider not able to control slide lets go of the throttle tyre re-grips while the bike is sideways causing high side.
    2 rider applies to much back brake in corner rear wheel to locks up skids sideways rider unable to control the slide releases rear brake making rear tyre re-grip causing high side. (this is the one i disagree with)
    to my knowledge the only reason the high side happens in this situation is because the rider took his foot off the brake. if he hadn't the tyre would have never regained traction in a sideways stance causing a high side. i am in no way implying that the rider would have saved the slide and lived to ride another day that's completely dependent on skill but he definitely would not have high sided.

    also i think romantix must drive round town quite a bit where you can mostly get away with that type of riding style. open road riding though i would respectfully disagree with you romantix. but in a way you did made a subtle point because locking up the rear is easier to save than collapsing the front which you pretty much have no time to react. it is possible have seen it done before but only once.

    and lets all not forget who's fault and who started this whole conversation to begin with...... it was a ninja named roger who disguised himself as a teaspoon. dam ninjas there everywhere <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->
    boy i just babble on and on don't i
    hope Dave doesn't kick me out for using up all the letters ROFL <!-- s:roll: --><img src="{SMILIES_PATH}/icon_roll.gif" alt=":roll:" title="Rolling LoL" /><!-- s:roll: -->

    lol, some interesting comments.

    i say alot of your breaking requirements are based on the situation and how much time you have to think about it. riding to work everyday for an hour ive come across an emergency breaking situation atleast daily. clearly the front is better for breaking as it puts alot of downforce onto the ground and stops the entire bike. my comment was more around emergency situations.

    an whoever said "how often you see that happen?" my mum's boyfriend rides a harley.. An he clearly stated that a car pulled out infront of him whilst he was going to overtake, panic'd hit the front break and went straight over the bars. ended up with broken collarbone and broken cheek bone with alot of facial road rash. (open face helmet) This is someone who has 25 years experience on a motorcycle, at the end of the day, if your going to come off, your going to come off, stick to what you know. my style of breaking has saved me on multiple occassions, sliding the rear end out to stop myself from hitting cars... the front break couldnt help me do that.

    if he has so much experience... why did he panic and do the wrong thing?
    and everyone knows that people who ride harlys are a bit past it...

    I find it very hard to believe that someone could endo something as long and low-slung as a Harley. I consider it far more likely that in his panic he locked the front, at which point the bike simply fell over. (an oversimplification of "tucking the front")

    holy cow romantix do you seriously ride an hour to work and then an hour home everyday! (well how ever many days a week you work.) that's insane. if it was epic hill roads and bays and mixture of scenery's and fast curves i wouldn't mind but me thinking you probly not that lucky or could i be wrong. i bet u stuck on long boring highway.

    just watch out for roger ok. roger dosen't sleep. . . . . he waits!! <!-- s:roll: --><img src="{SMILIES_PATH}/icon_roll.gif" alt=":roll:" title="Rolling LoL" /><!-- s:roll: -->

    I use both Brakes at the same time, especially in town where my bikes been hit numerous times. When it comes to emergency situations i grip clutch, front brake, back brake and lean back. But i think its wrong and a bad habit from DH racing.

    Braking doesnt heat the tyre, that would be causing an absurd amount of damage to the bearings (which i have to replace).


    And Romantix your not alone lol, 1.5hr ride from country into town for work. The poor Fizzer is slowly carking it too <!-- s:( --><img src="{SMILIES_PATH}/icon_sad.gif" alt=":(" title="Sad" /><!-- s:( -->

    Why do you say that heating the tire would damage the bearings? The tread / carcass squirms under braking; this distortion warms the rubber. Try it - take a relatively cool tire, and do some hard gas-and-brakes, then feel the front tire.
