Have you considered MotoLanna? Some members here have used them.

Thanks for the tip! Looks like that could save me ~$800 and avoid the 5+month lead times people have seen with tracdynamics.

Any idea on tire widths people have fit on the MotoLanna? The Ninja ex250 swinger just measured ~225mm vs the MotoLannas 218mm width at wheel axle location. MotoLanna is ~50mm longer ~25mm wider than the R5 so I'm guessing I could make the ex250 wheels work.

On a side note, youre so lucky to be able to have that Beta and have it registered with a plate. I live in commiefornia and we cant buy a new two stroke and get it even registered to ride anywhere public trails(no OHV sticker), let alone a plate. Insanity.

I feel your pain brother. I grew up riding off road in San Diego. Around 2002 while camping at Ocotillo Wells me and the wife decided we couldn't retire comfortably the way things were going. Upgraded our RV in 2004 and set out to find another state to relocate to. Settled on Cortez, CO after 5+ years visiting other states NEV, OR, UT, NM and finally Durango CO area. Bought a fixxer old house in 2010 and spent 7 years remodeling it until making the permanent move in 2017 and have not regretted it for a minute. Slower pace of life, lower cost of living, and far more freedom- including riding opportunities everywhere. Decision was made even before the politics, taxes, and invasion of people made it intolerable for us to stay. I tell people here the state of CA pushed us out! Last new bike I bought in CA was 2003 Kawasaki KDX220R seeing the 2-stroke ban coming along with all the other BS rules and restrictions and closures of our public lands  Finally upgraded here last year to a Beta 300 X-trainer 2-stroke. It comes ready to street legal register- only need to add a mirror to pass inspection, then pay DMV $7 to dual register and give me the street plate. Probably do that this year

there they are. cool and all.... but i have beta envy. swingarms going to be tricky and (obviously) the ktm one wont work, so hoping you have the ability to do lathe work, going to be necessary to get the ktm wheel in there on any swingarm you wind up using.

The Beta is a hoot to ride! I have it plated for both trail and road. Kind of needed in my area as bikes aren't allowed on all trail sections so you have to hit the black top to bypass those sections sometimes.

Yeah I was able to get measurements on the duke swingarm. 235mm width at the pivot so it's too wide. I'm still looking around. Might do a slightly extended tracdynamics or metmachex. Cost of both of those are sky high though when comparing against a conversion swingarm purchased off of eBay. Still hunting around.

Totally agree on the Beta. Bought a new X-Trainer 300 Feb 2022. Like a modernized version of original Yamaha Enduro concept. Has automatic 2-stroke oil injection (like hi tech autolube), adjustable powervalve, 2 selectable ignition maps, adjustable hydraulic clutch options, electric start and more. Love it!

MotoLanna is on order. Went with SuperTuff machined shock mounts and black powder coating. 2-8 week estimate on delivery.

Front fender on order. Bar clamps on order. Apparently KTM puts 26mm bars on the smaller single bore duke bikes. Converting to 28.6mm (1-1/8") gives me more options.

About the Beta, glad to see so many Beta fans here. I'm in good company! Unfortunately it might go up for sale this summer. I also have a KTM 500exc-f that just gets used more. Also have a 4y/o that I want to get into riding. I'm thinking of selling the Beta to pickup two trials bike for us. A Beta Evo for me and a Kuberg Start for the little one. We'll see... the wife says I have too many bikes. I think she is crazy

MotoLanna swingarm arrived! I'll try to post pictures up this weekend. Currently struggling to find a SR500/400 pivot bushing

IIRC, you can use your RD bushing (assuming you have it)

the one on the offset side?

I guess I was going off the details in this thread.

I'll test out the stock bushing tube.

Duke 390 wheel mounted. Got a killer deal on two basically new duke rims. Seller claimed only 5 miles and based on the looks I believe it! Only downside is the color--- they'll eventually be power-coated

Front fender likely not to stay

MotoLanna swingarm is here. I have been struggling to find a proper swingarm pivot bushing. MotoLanna was out of stock on the pivot bushing they make. Ordered one off of ebay from a XT500 and it is too long but also gulled up pretty good. Reached out to MotoLanna on when they'll be making more.

I'll also have to do something about the rear axle as it is a larger diameter than the Duke 390 takes.

SoCal250 - if you could help with the images again that would be great. I resized them to be 750x750 or smaller and they still aren't working correctly. Maybe it has to due with me using a Macbook?

downloading the pic comes back as a null image.   

[85RZwade]

My iPhone opens his pictures just fine...

I am able to download and view the last 2 images, 2582 & 2580. However if I try to attach them to a new post then insert them the message, they will only display with the filename and as downloadable jpg. Same as they are now. Not sure what's up with them.

If I open them for editing with MS Paint and then resave as a jpeg they seem to work.

That is a beautiful swingarm.
