    2006 KTM 640 Adventure

    who makes a chain guide and rear disc protection?

    I think Dual-Star does... but the main guy who knows has been out.

    ProMoto Billet makes a nice rear disk guard. An aluminum chain guide from a 620RXC will work on the 640A and can be ordered from any KTM dealer.

    I got mine from the KTM dealer, they said it was listed as a Husaberg part too. I had to do some minor mods to the chain guard & mix & match a few bolts to fit it but nuthin major. Vital bit to have anyways.

    Cheers

    On the same subject does anyone besides Scotts's make a front disc guard for a reasonable price.
    I think the Scott's is way over $100.

    Bill,

    you post that and then don't even mention that it is Scott's that makes the only serious guard for brakes? :D

    note it afixes to the axle, unlike the "bolt on" types - much stronger I am told.

    PS - pretty sure this was in the index somewhere...

    FYI on the beefier lower chain guide: the rallye folks only use a ~minor plastic slider in the rear, probably for the reason that rhys stated in his copied post above.

    660r

    Just like the stock 640 guide. I thought someone said the rallye folks use something even less substantial but I don't have a pic. Certainly on the 660r price is no object ($25,000 list?) so they would have put the beefier chain guard on it if they wanted it eh?

    My thought is the beefy guide might be a liability, as rhys alluded to above, and if the rallye folks get along without a substantial one then perhaps they are not necessary. But I do not know all of the issues involved... discussion?

    I went with the RXC aluminum guide on mine. I know the rally guys use the plastic fin, but I can't see what protection or benefit it provides long term. Perhaps they're replacing chains and sprockets frequently enough that it doesn't matter.

    I've run the aluminum guides on my EXC and MXC's desert racing and have never had a problem. Not to say it's not possible, but the guide on my MXC is mangled from rock hits, yet is still straight. If the chain and sprocket were taking the abuse they'd be toast and I can't see how the plastic fin would help much.

    At the moment I've got a TM Designs guide on my EXC. It's basically a hard block of plastic that's supposed to deflect and return to shape. Seems to work equally well but I don't think they make them for right-side drives.

    +1 the alloy/plastic KTM guide is pretty beefy, mine is scarred up from encounters with rocks but still straight.

    The main time you need the proper guide is when riding in ruts, the side of the rut will just deflect the std guard & flick the chain off. It happened to me a lot. I guess the Dakar guys don't see a lot of deep muddy ruts so they go for the unsprung weight reduction & just run the plastic bit.

    Cheers

    The std bit is just a plastic flap, I can see how it would deflect.

    The Rallye models use the hard plastic enclosure, same as inside your alloy plate. Doubt it would get deflected, but would get munted by rocks eventually.

    As I just posted above, no it is not the same as the stock 640 guide.

    The std flap won't do much to stop your chain derailing, whereas the captive chain guide used by the Rallye bikes (au naturale) and the EXC/RXC (plus alloy plate) will.

    The comment about the Rallye using something less substantal would be referring to the absence of the alloy retaining plate. Durability comes in to play here. Rallye bikes see the spanners pretty frequently in race use, so a short-lived plastic part would be OK. Rallye bikes are unlikely to be stuck on rocks & logs. Burying the rear up to the axle is sand is common, the plastic guide would work fine in those conditions.

    Hopefully clarified somewhat so ppl can make an informed choice, and get the parts order right first time.

    My local tech guy (and WP Suspension guru) commented that the KTMs are "a bit factory mechanic". Meaning that some stuff needs more frequent attention. eg the Kawasaki-spec fork dust seals he uses are more robust (at the expense of friction) but last longer and seal better.

    IIRC, I decided if I want to put a beefier guard on mine the easiest way was to get one meant for a husaberg.
