    Made these up the other day, I'd bent the radiators in a couple of very minor offs & thought some protection was required before the next trail ride - their main purpose is to support the side panels so they don't bend the rads inwards when the bike falls over. Made from 12mm steel tubing & 3mm thick flat with some rubber buffers to keep them from being pushed into the radiators. After some extensive testing the other weekend I can report that they work very well.

    The mudguard rubs slightly, but I think I can adjust it away. I had to trim away a small portion of the plastic louvers to access the inner bolts. but otherwise it's bolt on.

    Dang Clint those look great! And you actually get mud on yer bike too... :D

    Maybe you should be an aftermarket parts designer?

    I do believe Clint may have himself a "product" there... any other LC4 E/SXC/RXC etc. owners out there that would like to see Clint crank off a few for them... or are you just going to steal his design and run like hell? :lol3

    You'd better RUN!...

    Nah, seriously, steal away, I've barely got time to make bits for my own bike, let alone other peoples. Shipping & the fact that I'm excruciatingly slow at fabricating stuff would mean there wouldn't be much profit in it. Just buy me a beer when I make it to the States.
    I have to take them off to give them another coat of paint sometime so I'll post more pics and a few dimensions then if anybody needs further clues on how to make their own. Getting the bends in just the right place was a little time consuming but there was no rocket science or expensive tooling required anywhere.

    Cheers

    Those look great. The bottom of my left radiator on my 625SXC is bent almost to the frame. It isn't leaking, and I'm not overheating, and I don't have the time for down-time right now.

    What a terrible design though. Why would they make the radiator a structural item is beyond me. "Hey, if the bike tips over the radiator can take the blow!" This is even worse on the SXC since the shrouds bolt directly to the radiators. At least on the 18 and 27L tanks the tank can take some of the force.

    I wish I had known about this when I bought the bike. Now I need to get both radiators straightened before I can add some guards. An ounce of prevention...

    If your radiators are straight, get guards now.

    Does anyone have suggestions for good aftermarket guards that will not significantly affect air flow? Are there any made that can be used with the fan?

    I have been considering these guards for the LC4 radiators, but I might have to modify a bit to fit the cooling fan, or leave off the rear support, as the SXC doesn't have a fan. I have already made a couple of supports to go completely accross the radiator (sorry no pic right now), a bit of lathe time, and they worked ok, but I'm thinking of improvement.

    Figured since this was in the thread index its a good place to tag it in.

    Maybe I missed it (I am a mere mortal after all!) in the bleeping thread index, but I'm on the hunt for radiator protection for an 03 625 SXC. Any leads?

    Many thanks. :thumb

    Hmmm, they have come up here and there, but you might be right about not having all the info organized... so as I recall one of the better options is the Bullet Proof Designs setup:

    http://shop.bulletproofdesigns.com/product.sc?productId=49&categoryId=9

    It looks like Chris Blais' company is a Bullet Proof Designs reseller:

    http://blaisracingservices.com/bill...c4-radiator-guards-39-02-39-06-/prod_545.html

    There might have been others, and folks making their own, which is indexed. :beer

    Thanks dude. I did come across the home made ones like what Clint made which BTW look really good. I wish I could weld...I might go learn as I have alot of ideas but no way to do any of them...also, wouldn't it be great to be able to machine things? My buddy got one of cjracer's clear clutch covers for his SE and that thing is a work of art.

    Anyway, I'll check out the links you posted. Many thanks David. :thumb

    Nice work!

    One thing to watch for after a few years & a few crashes is cracking of the radiator mount s that the guards bolt to. I've had to weld one of mine back on. This is definitely cheaper & easier than fixing radiators though!

    Cheers

    You're hard on the gear mate! I was thinking about welding in a little gusset between the 2 rad mounts across the front of the frame tube if mine needs fixing again. It would only take a small piece of metal to add a lot of strength there.

    Cheers
