    $700??????? I paid $100 for the knobs for the K6, fitted them myself in 15mins. That price is outrageous!

    I was wondering if anyone has any fedback about frame sliders. I can get those $50 on trademe for my bike, but apparently as per one of KB members:
    ...Don't get cheap ones, they are likely to bite into the tarmac and flip your bike or snap off bits of the frame / engine....
    What do u guys think of it?

    I think the ones on trademe are alloy whether other are rubber. Alloy is pretty soft i would say.

    I think the chrome or carbon looking knobs are just for the looks on the outside while the inside is still made of the black delrin (plastic).

    I bought the cheap crash knobs off ebay for the old 929 for cheap but I did not use the bolts that came with it. I bought some better bolts from a hardware shop (at least that is what I was told by the bolt shop). I have seen some of the cheap bolts snap off in the event of a slide while the better bolts should just bend protecting the fairing..

    Those $50 from trademe arent plastic i dont think. It says "CNC Machined and polished Aluminium", thats my point, which one are better plastic or aluminium?
    Would the aluminium dig into the road while plastic wont?

    Hmmm...I stand corrected then. I know the delrin will just shave off. I hope the frame sliders will not dig into ground because that may just cause the bike to flip. Sorry not much help here...perhaps someone else can give you a more difinite answer.

    Dont buy too cheap, you want them to grind down if they hit tarmac, not dig in and snap off (cheap bolts/poor mounting) or flip the bike

    I think i will give those $50 dollar ones a chance, since im broke atm and any protection is better than nothing, however, i'll get better bolts.
    I'll let you guys know how good they are (quality wise - im not going to drop my bike on purpose to see ), i will probably be getting them some time next week. (my bike is at panel beaters now).

    Be careful substituting different spec bolts. The sliders, bolts and mounts have to work together to hold the bike up and wash off speed. If the bolts are too stiff then the mounts will have to absorb more energy - perhaps more than they were designed to handle.

    Was quoted around $700 (including installation) for some Oggy's on my new CBR (non cutting) but hoping I can reduce that somewhat....

    This has been discussed a few times now........PLASTIC:
    • Acetyl-An engineering plastic well suited for the role of crash bung, However the material is a little brittle and of more concern is the danger of spontaneous combustion and the consequent release of formaldehyde.
    • Urethane-The material used for skateboard wheels. This material is to soft, a real danger of the bung ripping through the holding bolt exists.
    • Nylon-The mother lode. [Nylotron, or Nylon 6] Available from Engineering plastics or Ludowici.

    Yup. Glass filled if you can get it, very usefull material for high local load applications.

    Got mine from Rapidart in Hamilton. When the time came they did their job well (the right hand side anyway). Partly ground away and about a 5 degree bend in the bolt but no frame damage and kept the radiator clear of the ground so dirt cheap at $150.
