    I found this thread a couple of days ago and started reading. Only one thing to say about it... very dam COOL sanjoh! I'm a big fan of "non-stock" and bobbers and such. I'm cleaning up my CBX this winter and putting the finishing touches on my TW, extended swingarm, adding a fan for my radiator.. modding my harley fatbob tank to fit.

    I expect this will all be done by spring.. so I'm going to be looking for another project. I think I'd like to build my own "Dirt Ninja"! Or perhaps some other street to dirt hybrid, really it's going to be dictated by price.. so whatever goes for cheap will likely be my victim unless there are mechanical factors that prohibit said conversion.

    I'll say it again... your dirt ninja is way COOL!!! :clap

    Gonna do some updating on the Dirt Ninja over the winter.

    Foot peg relocation - gonna need a new exhaust hanger and luggage rack lower mount as the aluminum footpeg holders are coming off

    Swingarm extension - Just a few inches, any suggestions on how to do this? Was going to start with 2 swing arms and join the rear parts with a support splint on the inside made of tubing.

    Exhaust reroute

    Skidplate

    Recently acquired a KTM 950 SE and all I can say is the Dirt Ninja is a very capable enduro:deal

    I regret selling mine, so I'll probably end up buying the next ninja 650 I see pop up for the right price. My buddy just bought a 950SE, after riding it I was strongly considering selling my vstrom for one, had to practice some self restraint.

    is that earley swingarm rectanglar or not, I was looking at that on another site where they extended it 1 inch, but i was thinking also 1.5-2 by fitting a thick wall rect tube inside, cutting the original at a verticle v for more weld area, fitting the original adjusters but this is all speculation on my part while i am still shopping for the bike. otherwise it looks like it is a complete refab out of rect tubing. and i may not need it for my app.

    Sanjoh,

    Using a second swing arm works pretty good, that is what I did. The correct size, thickness and alloy how can you go wrong? Just add on to the back. I only did an inch, didn't want to change the length of the bike to much. Absolutely no negatives that I can find from this mod, but a lot of positive. And you can buy them for about $15. The gussets are also from the donor swing arm, the brace sawed in half.

    The SE is a hooligan bike defined, felt like trouble the first time I sat on it:D.

    Why only an inch? Any pics of the swing arm on the bike?

    Why only an inch, I'm conservative. I was concerned about getting the wheelbase too long and affecting handling. If I remember correctly 1" of length gave me almost a 1/4" of travel. The bike still turns very good so I would not be afraid to try a little more length. If you look back in my build thread a few pages you'll see the the swing arm mods and inner fender changes. These changes really had an impact on the bike, it felt like going from a playbike to an offroad bike. Before it was pretty easy to bottom the tire into the inner fender, now I can't. I recently had a chance to ride this and my KLR back to back. I was hoping this bike would be a more powerful KLR, but what I got is a far superior bike. This rear suspension with the mods and R1 shock works really good and the KLX front is awesome.

    You mentioned something about a KTM comparison with your bike, care to share more?

    The SE is very planted off road, on road it is a bit sluggish turning but it will turn with the proper inputs. The ninja turns great on road, but off road is a bit more skittish. I think it has to do with the wheelbase and the weight distribution, with the ninja, the weight is rearward oriented. I think extending the ninja swingarm 3" or so would make a huge difference off road and I'm willing to live with the on road handling changes.

    I think the wheelbase on mine is 58 or 59 with the ktm forks.

    Did the longride seat fit on your teckno?

    Nice bike! I have looked at a couple of these 650s now and it seems they make great adventure bikes... I have been looking for a bigger bike andI have been messing with the idea of building something similar. how is the gear spread? I know my ex500 motor had a low enough first gear combined with the bottom end torque you could really lug it down.

    I've changed the rear sprocket to a 52t, front is stock 14t. Nice low end, plenty of torque to bring the front up in slow speed off road conditions. Highway speeds are no problem for hours on end.

    Loaded with 3 givi hardcases, running around 75mph it will get 51mpg, range with combined holigan right hand is around 180 miles.

    I just bought Denvet's Thinja, it's still in VA & I'm dreamwheeling here in AZ. I was wondering about the lack of a chain guide on the swingarm ahead of the rear sprocket for offroad? No matter where you ride here we get into rocks occaisionally.
