    The sucky search engine won't search such a short sentence.

    I purchased my first Dirtbike. Got myself an early Christmas present. Thiry years of riding and never really did my dirt riding. I rationalized it by saying it will be good healthy excersize

    I will need to swap out the springs because I am oh, about 200lbs heavier then the original owner. The rear shock is an Ohlins. Is there a place in town (denver) I can get a spring ordered and swapped? I suspect I will have to do some homework finding forks springs.

    Nice, I've always liked the 600 class ATKs. Never had one, but always liked them.

    Sorry, I don't have much specific information, BUT...

    Google is your friend when it comes to searching advR for short search terms.

    Search whatever you want, and include "site:advrider.com" in your query.

    eg "site:advrider.com atk 605" and all of your results will be limited to advrider.com. You can search individual threads, and i believe subforums this way as well.

    Looks alot like my old XR600 except for the switch around on the rearbrake/sprocket. I dont think we have them in Oz but I like the simple shock/swingarm setup.

    I read somewhere (on here ) that the first ATK's were a frame and suspension kit for the xr 600, but that would be a Rotax engined one.

    And from memory the early ones had an off set linkageless monoshock (just looked closer at the first pic and realised that one does to...), and the rear brake disk was mounted on or near the counter shaft sprocket.

    We had a few in OZ, I saw one in the flesh in the early 90's, and there was two for sale on bike point not long ago...


    Anyway to answer the OP's question, I personally know bugger all about them but this thread http://www.advrider.com/forums/showthread.php?t=431258 has some info on them.

    Try a google search on the ccm604. Different bike but many similarities. I'll see if I can dig out a picture once I start my other computer later. A good source of info would be ccmriders. Ignore anything on the ccm644 as it is a later suzuki engined bike.

    I might even still have an engine manual and fork manual somewhere on my computer. I'll let you know.

    When I was looking to upgrade from my XRR the ATK was on my short list due to it being a good bike for a big guy like you. (and me)

    What scared me away was zero dealer support and parts availability.

    But everything else was there: bulletproof engine, great suspension and brakes, E-start, sick HP.

    From the limited research I did they are made by Cannondale or a division of Cannondale USA which makes them the only dirt/enduro bike made in the USA. The Rotax engine is bombproof but had issues with cam chains or similar...easily sorted. They all came with top-tier suspension stock and had great trail manners for a +/- 300lb bike.

    I could be talking out of my ass. (all this drivel is off the top of my head) but look up the ATK thread on this forum...should be a good start.

    I would imagine replacement spring for that Ohlins will not be cheap but well-worth it.

    I had a 440 kitted 350, basically a smaller capacity engine than yours, everything else the same. Oh and motard'd

    [​IMG]

    The Rotax is a great engine, tons of oil capacity great dual sport engine. I sold mine for the same reasons mentioned above, lack of spares and knowledge about them. If your forks are Paioli's then they have been installed aftermarket.

    My main fear was damaging the tank. Due to the frame through the petrol tank design, i never saw an aftermarket tank available, so trying to source a spare would be very difficult.

    It rode very similar to my old XR600, but compared to modern bikes it is a bit of a dinosaur. They feel very top heavy and tend to fall into corners, but having said that, thay are a wonderful unique bike, so if it is trail riding you want, you will probably have a ball. If you want to start covering some serious miles, probably best to look elsewhere.

    Thanks for all the heads up. I kind of wish this was the dualsport version. It will be plated and ridden to the trails. It will be wierd not having turnsignals for a while.

    BTW, my bike happens to be the 490. I see a lot of info on the 605 and the small bikes. I think the 490 will be a good beginner bike.

    Here is the ATK Thread:

    http://www.advrider.com/forums/showthread.php?t=431258&highlight=thread

    I rode one of the latest (1999?) ATK 605 dual sports about a year ago and it ran like a scaled ape even at 7000ft elevation. It was fast, fairly comfy, it was a bit taller and felt as light as my DRZ 400E but with more power. I really like them and wished they had stayed in production. I was going to buy it but the guy wanted too much for it.

    It had the Paioli forks on it and the seller said they were stock? Also, I think the only real maintenance other than oil changes to the motor was the cam belt. I have heard you can still get spare belts.

    Find a suspension shop in your town, I bet they can work something out with you on the springs, I suspect it won't be very pricey.

    Enjoy it!

    I been riding a 99 605 for the last year as my dual sport. ATK is still in business so you can call them for technical help though now days they are limited on older parts. The Rotax motored bikes are still being build by American Dirt Bike and called Avengers now but they are virtually the same as yours and my bikes. They've got parts and are very good to talk to as well for tuning advice. There are several ATK forums here, thumper talk, ATK usa to name a few. During the summer I set mine up for higher speeds on gravel roads and during the winter set it up for slower muddy forest service roads.
    You are welcome to ask me questions being a little farther up the learning curve. I 've put about 2,000 miles on my 606 in the last year and the only problem I had was the voltage regulator so it over charged my battery, turning my bike into a kick only no lights dirt bike. But it didn't effect how the bike ran so was able to finish my weeks ride just wasn't street legal anymore.
