  • crosstrainingen... DR650 fork conversions? Worth it? What's involved? We look at DR650 RMZ fork swaps. DR650 forks suck. I get plenty of questions about adapting forks from other motorbikes. But alternative forks are always a much bigger job than you think. I always suggest trying the easy stuff first instead of a DR650 KTM fork swap. Ultra budget DR650 suspension mods? Welcome to Cross Training Adventure, we are into all things dual sport and adventure on the east coast of Australia. Just try 10w fork oil and make longer fork spring spacers out of PVC pipe to compress the way-too-soft part of the dual rate springs more. So simple instead of a DR650 YZ fork conversion. Next? Aftermarket valves which you just drop into your forks and work like proper cartridge forks. In Australia the Plex valves and DXF valves are common. In the US? Cogent DDC valves and Teknik Platinum Fork Valves. Keen on adventure riding in Australia? Check out our vids. Most riders find this is all they need instead of DR650 fork swaps. Next level of suspension mods upgrade instead of DR650 fork swaps? A common conversion uses RMZ250 or RMZ450 forks. Plenty of these available. Some owners have reported the work involved. See our pinned first comment for the relevant links. YZ450F and WR450F fork conversions are fairly popular. The 250 forks work as well. One advantage here is you can find wheel bearings to fit the stock DR650 front axle. If you google around you will find other conversions too. KTM forks. DRZ400 forks. These are very long forks, you will have quite a bit of fork leg sticking above your triple clamps for these DR650 suspension mods. Now the difficult stuff with DR650 fork conversions. Upside down forks. There's a lot of work involved. If you are just an average rider I doubt it's worth the effort. But you may just like the modern look of course. Here are are the potential problem areas with DR650 fork swaps. Do the triple clamps have the same head bearing sizes as the DR650? Which will suit you? Unfortunately I'm not qualified to advise you. Do your research, explore all the options, and decide if you want a major project on your hands. Find 43mm forks that will just slide into the DR650 triple clamps.These DR650 fork conversions work great! You can use your stock DR650 wheel, front axle, wheel spacers and even your speedo drive. However, you will need to create a caliper adapter plate. You will also need stiffer fork springs, the RM125 springs are only 0.356 and the RM250 springs are 0.44. If not, can the DR650 head stem fit the other triple clamps? Is the head stem the same length? Most of us buy a YZ or WR450F fender in the right colour which usually looks better and wobbles around less than the stock one. The bike will sit higher at the front end. Good for inline stability but less likely to turn. You may like it or dislike it. You can slide the forks up in the triple clamps to offset this to some degree. And finally, you need to mess around with spring rates, fork oil and revalving to get the most out of those new forks. Often you will need a spacer. If you like dual sport riding in Australia then you might like our adventure riding vids. On Ebay you can buy brackets that will fit various size fork legs. Search for 'Headlight bracket 37-45mm fork tubes'. Full lock will usually be different and the forks may hit your tank until you somehow build up the steering stops. Front wheel? Two options here. The easiest option is get the front wheel that matches the new forks. It will have a smaller front disc so you'll need to buy a 310 or 320mm motard disc and disc adapter. Expensive, but you'll have slightly better brakes. And of course you lose your speedo. Option two? Create a caliper adapter plate and wheel spacers that will let you adapt the DR650 front wheel. It can take some fancy machining to create wheel spacers that will accept the DR650 front axle. It can be tricky to retain your speedo drive though. You may need to buy an electronic aftermarket speedo. Front fender? You can just drill new holes to use the stock fender. So... still interested in the upside down forks despite so much work needed? Have you done a conversion? How did it go? If you have any good links, let us know and we will post them in the pinned first comment. This is one of our three channels, there's also a Cross Training Trials channel, and a Cross Training Enduro channel. All three are equally dodgy.

    TC 49mm USD units. They use the exact same stem bearings as the DR again. If you don't want to have to fiddle with the wheel you can lathe up some bushings and use a DR swingarm axle as a new front axle. Slap a 320mm disc on your DR wheel and grab a 320mm caliper adapter (same bracket as a DRZ-S) to bolt to the fork leg. The 49mm unit is very similar to the modern 49mm forks used on MX (Kawasaki, Suzuki, Honda) bikes 2017+ so you are able to poach used stock springs off ebay to get 48N springs that are just about perfect for the DR. Set a couple screws in the steering pads to remove a couple mm of travel and you are good to go. TN indirectly posted a walkthrough on it in his bike rebuild thread on DRRiders, "Noble's Bike Rebuild" in the General Forum. Fork swap started towards the end of page 35.

    RMZ FORKS THE BEST OPTION?
    If you want upside down forks, RMZ seem to be a very popular option as they are so common and the standard springs and valves work well!
    Albert Falls says the triple clamps fit straight on. But yes, have to ditch the ignition. So no steering lock and have a hidden switch on the bike. Made a spacer for the axel on the lathe and fabricated a caliper bracket. Ditched the speedo and went digital. Also had to weld some bar stoppers on the frame otherwise the forks hit the tank, and would probably damage a lot of stuff on the bike in a crash without bar stops. I had to find a DR400SM headlight bracket. The stock one didn't work obviously. The turn radius is pretty bad but I have a long range tank which probably doesn't help, it's a lot fatter. But it's never been a problem in the bush. I live in Canada, so the forks soak up the rocky terrain nicely without bottoming out

    I went nuts on a CRF230F dual sport build a couple years ago and did the Emig Racing triple clamps and early 2000's CRF450R forks. Even after having them revalved for my weight and riding style, they were still too firm and stictiony. I figured the guy was an expert fabricator and this swap would be the ticket, but I ended up selling it off and going with an XR400 front end swap. Much better suited to the bike and riding style. One of the biggest challenges when fork swapping these older style models is condition and parts availability should something break. I had to scour E-Bay for a replacement compression adjuster.

    Swapping out the forks to a full size USD on my 650 is something I've wanted to do since I got it, I'm not even a really heavy rider, but the factory forks are just straight up spindly in every direction. I've kicked around the idea of a twin front rotor setup too, give it that big boy adv bike look and a front brake that bites... Maybe in a few years time when I get a machine shop in the garage... Even with stiffer springs that keep the suspension at the top of its travel most of the time, to me the bike always sort of feels like the front wheel wants to fall through the pavement, or topple forward, the front end just doesn't feel high enough to me.

    Let’s get this straight at the outset, I don’t own, nor have I ever worked on a DR650. However I have done a fork-swap (on a Honda Innova!) twice. Can’t see how it’s any different to a DR650, so here goes.
    Always, always get the entire front end of the donor bike, forks, clamps, steering head tube, front wheel, brake and calliper plus all that goes with them. Trying to make another wheel fit is a pain, a lot of extra work and will want much fiddling, sorting and modification that you didn’t ask for. (Do you need to ask me how I know this??)
    Measure head-stock bearings for your chosen donor carefully (ID and OD) and see if they match the original bike (DR in this case). If not see if available bearings can be sourced so you can fit the donor headstock straight to your frame. There are common sizes of proper head-stock bearings in many cases, but not all. If not, then you’re into making bearing carriers on a lathe, to fit into your frame, or else fitting a new steerer-tube to your donor headstock.
    Shortening the steerer tube is not a big deal (saves using that spacer you showed). Cut out the required amount from the centre of the steerer tube, turn up a 3” (75mm) spigot to fit the centre of the steerer tube, bevel the tube at both cut ends and weld up with the spigot down the centre to keep it straight.
    Hope this helps. I’m assuming that ALL Australians have a lathe and welder in their sheds!!

    A buddy did the yz250 conversion on a 2011 KLR. Took some machining for a Trail Tech dash and triple tree. CBR600 brake master and a giant rotor. He eventually parted the bike out and I ended up with the whole converstion for my 2011. With longer dog bones, and stock shock with a stiffer spring, the bitch likes jumps and trails. Really great difference...BUT...I have a 2009 KLR now and put the guts out of my 2011, with Ricor Intimidator valves and Progressive springs and it is darn comparable to the usd conversion. It has long dog bones and factory rear suspension...so it's not as high as the 2011, and sometimes I think of geting a stiffer spring for it. I have the conversion forks maxed to the fork cap. I like the rake and height even though I'm only 5'8. My buddy never told me how much he had into it but sold it to me for $600. I'm sure he was into it for at least $1000. The big rotor will set ya back at least $300. And the upgraded factory set up was roughly $400.
    They ride similar, but the conversion has a bit more tailored feeling, better braking, higher clearance. The upgraded forks severely correct the horrible brake dive. I mean I've flatlined the stock forks in a couple years, 25000km of trails and commuting🤣 I ended up wrecking the CBR master so I put the factory KLR one on and it works fine.
    Over all it depends on your budget or curiosity. Factory rear shock is a really good piece of tech, just requires a better spring. USD forks are prone to seal leaks, the factory seals are basically indestructible, unless you remove the fork boots, then the sun will rot them.

    @FonicsSuck 11 місяців тому +5

    My nickles worth of opinion on making a longer spacer for the stock 650 springs.
    I don't recommend adding preload by compressing the springs more. That can cause you to top out the forks more often.
    Alternatively, I would cut the soft portion of the progressive spring out and replace with a spacer equal to the amount cut out. Just ensure that you still have adequate compression space on the spring equal to or greater than the fork travel. Most springs can be trimmed without risking complete compression of the spring (which you never want).
    This will effectively increase the stiffness of the spring without increasing preload.

      Absolutely agree. I have done this to two different bikes, and it worked great. While you can increase preload to get the correct sag with you sitting on the bike using too soft springs, they are still too soft. Also, the bike will now sit too high unloaded. Get the springs and preload combination that gives you the correct sag for both the bike alone as well as the bike loaded with you and your gear.

      Good point but they'd have to be pretty long spacers to top out the forks. And you'd probably need three guys pushing down on the fork caps to get them back on!

    • @64faffi
      @64faffi 11 місяців тому +2

      @@crosstrainingadventure Actually, you need less force because you need less preload. Personally, I have found that if the spring rate is correct, you want the spacer to sit about level with the fork top, giving you about 10 mm, give or take, of compression before the threads engage. If you need it to sit more than 10 mm above the fork top in order to get the correct sag with you sat on the bike, your spring is likely still too soft. At least in my experience.

    Can you please respond to my comment here? Watched your channel for many hours. I own a 2021 Dr650 which I purchased in New Zealand one of the last ever to purchase legally. Why is the fuel consumption so bad? I only get about 17-20 kilometers per litre of fuel used. How can I tune a stock Dr650 correctly? Why is the fuel consumption so bad? Thank you.

      EFI is a lot more efficient than a carb. Also just an old engine design. 20km/l is my average. 22 if I just sit on 80kmh on the highway. 17 offroad. I was shocked when a riding buddy bought a 690 and was averaging 30 despite being on the throttle a lot more than me (KTM's stock tuning which was very lean).

    Are the upside down forks lighter?

    • @64faffi
      @64faffi 11 місяців тому +3

      Usually, they are a little heavier, because the heavier outer part of the fork leg is much longer. Their main advantage is more rigidity that again lead to more precise steering. Their main disadvantage is that they are more prone to stanchion damage from dirt and gravel with resulting oil leaks. Under extreme braking, they typically have a little more stiction than conventional forks, but this is unlikely to happen during dirt riding or street riding. Overall, the performance of and USD fork is better than that of a conventional fork, but few riders would actually notice. Correct springing and damping are much more important.

      Supposedly, the rmx and rm right side up forks of the late 90s are some seriously good off-road forks. Must have been pretty special for the pro mx riders to go back to right side up, after usd was commonplace for over a decade.
      I imagine this would probably be the best match for the dr650. Some flex to match the chassis design and Enduro use, more durability, but also come with decently modern valving.

      I picked up some 2006 RMX250 forks for AUD200. Local suspension guys adapted them. The strange thing is these are working really well with the stock springs and valving! We figured changes would be needed but they are fine.

      I think the rmz450 fork combo ends up lighter (based on just having done it, and physically handling all the parts). But even if they were the same, the unsprung mass is lower, which means it follows the trail bumps and dips more nicely.

    • @andrewstambaugh240

      You don't have to drive it like an MX bike to appreciate USD forks. They are a massive benefit for trail riding and help prevent situations from becoming sketchy accidents.
      They have clickers, so you don't have to keep opening up your forks to get your tuning right. *Rebound tuning is the biggest gain here.* Not blowing corners is where that benefit matters the most to me, but not getting bucked is nice too.
      They also are more responsive/predictable to oil and valving changes vs emulators, and as stated, you have clickers so you can fine tune it vs needing to valve perfect (or give up).
      They are typically more rigid.
      They have significantly less unsprung mass - which helps a lot for trail responsive grip while remaining supple.
      They cost close to the same as emulators and way less than over the shelf modern forks. (approx $400 for a front end conversion if you make sure to buy a set that comes with the triples)
      They come with the option of raising the bike (I opted for barely lowered vs stock but with adjustment range that exceeds stock height)
