xs650 diy hardtail 123 587x374 DO IT YOURSELF XS650 HARDTAIL KIT   The ARDTAIL!

Jon ardcorechoppersIntroducing the latest product from Ardcore Choppers for the garage builder. The ARDTAIL! After YEARS of getting requests for a DIY hardtail with the killer lines and quality we are known for here it is. We have listened to the issues the average home builder has with the installation of other kits and working with some friends of ours in the industry we have developed and are offering the easiest to install XS650 hardtail kit on the planet, PERIOD!!!!! Not confident in your welding skills on something as structurally important as your frame? NO PROBLEM! You could literally epoxy this kit on with no worries! Of course we do not recommend this but you get the point. When we set out to do a DIY hardtail kit the three main problems/improvements we repeatedly heard and felt could be improved upon was first making the hardtail easy to square up with the front frame section.

To address this our design is a no brainer utilizing slugs and triangulation. Since we are using the engine as a jig and the stock back bone to positively locate the hardtail in addition to the factory lower engine rails its as simple as making 3 cuts, then remove the old frame section and slide the new rear section into place! Second was the amount of time spent cleaning up your stock backbone. Cutting and removing your old seat rails, the factory sleeved gusset and lower battery tray rails in addition to finishing the backbone after surgery was very time consuming. THIS KIT ELIMINATES ALL OF THAT! And lastly was the possibility of grinding/cutting into your backbone to deep when removing the factory rails causing a weak spot.

THIS KIT ELIMINATES THAT POSSIBILITY! Each kit comes with detailed step by step instructions. If you can read a measuring tape, cut 3 decent straight lines and weld two pieces of metal together you can install this kit in a couple of hours! Each hard tail is jig built based off a STRAIGHT stock frame and engine meaning when you go to install the kit it’s going to fit (provided your stock frame is straight). As with all of our products each kit is heliarc (TIG) welded, NOT MIG WELDED for great looks and superior structural integrity.

You have to wonder why most racing organizations and the Aerospace industry either recommend or mandate TIG welding on structural components! After that statement, how and why can we offer a kit that can be MIG welded? First, our kit is designed so the welds you do at installation basically just keep it from slipping apart. Even if your welds fail our design incorporates the engine and rear mount as a fail safe. And most importantly we understand not everyone has access to a TIG welder or the welding experience to use it correctly.

With our kit all the structural (critical) welds are done for you as the main stresses are carried on and in our welds. We could go on and on about what sets ours apart but since WE ARE and HAVE BEEN at the forefront of the modern XS movement do we really need to? Our intent was to have 10 of these on the shelf ready to go when we announced the release. Word leaked out and the first ones are gone so expect a 2-3 week turnaround. Cost is $325.00 with $40.00 shipping. Granted a little more expensive than the others, but to us the ease of installation and time saved is well worth it. Remember quality isn’t expensive it’s priceless.

    Guys,we are working on finding reasonable shipping rates overseas.. So far we aren’t having much luck due to the odd size of the tail section.

  2. nooch says:

    is this tail designed to use the stock rear wheel and axle?

    1. David Williams says:

    Does this hardtail fit every year of xs650?

  8. Daniel says:

    This thing looks AMAZING guys, GREAT JOB! My name is Daniel and I am working on a 81 XS400 and am looking for something exactly like this since I am removing the 2 frame rails that go from the neck to the upper engine mounts and only keeping the backbone. That being said will this kit mount up to my 400 (with some obvious modification)?

  9. Q says:

    nice product but i cannot ever get ahold of any one at this place im wandering if there going out of buisness i call 3-4 times a week for a couple weeks

    1. Calvin says:

      I ordered one a few weeks ago they are about six to eight weeks behind on them. it took me a few weeks to get ahold of them also.

  10. CryptoKnight says:

    Has anyone built one of these, and can share pictures? I ordered a 4″ stretch & 2″ seat drop, and am looking to start sketches for fabrication, but can’t find pictures of Ardtail bikes. Anyone have a side-on shot, ideally both left & right? If I can project a side shot (90-degree) left & right on a wall, I can start to rough out my fabrication sketches, but until I know the dimensions, hard to start. :-)
