Frame Geometry for the 350X, 250R and XR600

[Ingrid Cold]

Does any one know the frame angles of certain 3 wheeler frames? Looking to convert an XR600 in the years to come and wanting to get my angles correct, IE no choppers. Would like to have the specs for some 47mm triples to run a leading axle front end and keep the proper geometry of the front end and not throw abunch of crap together.

I'm going to work on a database to allow people with a dirt bike to make a proper trike, and not some Junk Yard Dog. I don't want my swingarm coming out at a 60 degree angle and my forks so far out I can see the front tire. I know 350X triples are supposed to be the ticket, but would like to try and find the spec of the down tube and stuff.

Great thread itdea !!!!!!!!

I've asked a question about the 85 VS 86 Tri-Z for this very reason. I also have questions about a swing arm I'd like to build to put on a bike. I'll make a separate thread when the time comes as I hope you will, but for now I hope we can get some input on here.

There's some good info in here.

Pretty simple, if you are going to use a leading axle and you want it to handle well, build it to a Tecate spec. Do not use "staggered" tripple trees.

Measure it. Not that tough. Ever heard of a clinometer or a pitch calculator? Now you have. There's no demand for a database when the solution is so simple.

Just putting it out there- there is a pitch calc app for i-phones, really accurate too. Sometimes i use it for a roof pitch/rafter angles, i know sounds silly but it works- especially if your hanging 40' on a latter its easier to bring my phone up than a square+level for pitch. I dont know maybe it'll help...

What a stupid post, your mental midgetry knows no bounds. Measuring is one thing, comparing the results to a know chassis set up requires information some may not have access to, like say a Tecate chassis. If you have nothing to add why not just fug off?


PS. Thanks for putting all the data together in the old link I posted Barns. Good stuff!

I told him how to do it himself. You fvck off. People don't have to do things your way just to please you.

You answered nothing, all you did was inject your special brand of duchery into the thread. Stick to what you know and go beat some nails straight, or better yet just go whack your tack.

The greatest enemy of knowledge is not ignorance, it is illusion of knowledge.

I know it can be done with minimal work.... but I want to know the numbers and what I'm dealing with, not just guessing and cobbling together I'm getting off ebay. The USD fork swap comes to mind here on the XRL, people were going crazy over it, using triples that were stuck out farther than the XR had stock, then putting forks with 1.1 inches of extra travel and then bragging about how well they turned. Same thing for that POS FCR carb. If it's cool do it, dont ask questions. Billy Bob says it's a winner. And the earth may be flat too for that matter.

For some of us, we have to know why the sky is blue, or what will be advantageous at speed, and what will be better in the woods, we all know the answer, but few people know what is going on, show me hard evidence, show me the numbers of the angles, show me how you over came differences in the frames, other than bath salts and a Lincoln Tombstone welder.

Oh well, this thead escalated quickly.

Read Zen and the "Art of Motorcycle Maintenance, an Inquiry into Values", it will help you understand this quest. If people are so smart, lets see your proof, other than "it just does".

I'll be in contact with you later for some "lite" brain picking if you don't mind.

No prob, not that I have much brain left to pick. There's also a few others here like christph that know quite a bit about the TECATE...The Most Powerful 250cc 3 Wheeler In The Universe!

You can send me a pm if you want as well.

That PM stuff sounds very Milneresque

What exactly is it that you are doing here then? Hmm?


I provided a suggestion for a proven method of figuring frame geometry and a tool to use, which even if the database is pursued, will help any willing participant. I'm a professional motorcycle technician that has built multiple custom framed bikes. What do you have to offer Shawn?

Please share a picture with the class of a frame that you have raked.

I'm not trying to say that you're useless, I'm just saying that the best part of you ran down your mothers leg.

Well “the dude” I have posted more than few mods, builds , and suggestions over the last year or so and also just interacted in a somewhat positive manner. You for the most part just post the diarrhea that flows from your seemingly constipated brain. From what I can gather you’ve been banned multiple times and continue to come back when nobody wants you here. Instead of re evaluating your actions you continue to take selfies in a busted gold chain while driving your moms Chrysler 300c around Iowa. At this point I wonder if you’ve ever even ridden a three wheeler let alone own one. Now please run along and let the man continue with his very excellent thread idea.

I like both ideas. The Inclinometer and some info on existing frame angles. Why don't you guys edit your posts to get rid of the trash talk before the moderators blow this thread out. I would like to see where this goes. We are all here because we are weirdos that still like to ride 3 wheelers. Maybe some really cool machine will be built due to the discussions here (if we can give useful info). Wheelie on dudes!

I wasn't planning on posting anything about this for a while as I'm giving myself two years to complete this and wasn't even planning to start for another few months, but seeing as I have a lot of questions and issues to deal with I figure this thread is as good a place as any to start asking them.

So this is what I want to turn into a trike. I've had my eye out for the right donor bike for a while now and this one came up the other day for the right price and in the right condition. I'm hoping to do this build in a way that if I do have to throw in the towel at some point I'll still be able to make it back into a bike, but if not and it does become a trike I'll have lots of spare parts for my other girls.




The rake looks to be about 2° less than my TRI-Z which should be easy enough to adjust with the rear shock location if that ends up being the desired rake angle. However I'm planning to use the KTM WP forks which are easy to shorten, but have a leading axle vs the trailing axle on the TRI -Z.

The biggest investment aside from the price of the bike is going to be the front and, so I want to make sure I get it as close to perfect as possible on the first try.

I spoke with a buddy who used to be a regular on here they gave me a few recommendations four guys that might be interested in building my triple tree. I plan to start contacting them early next year, but hope to have some idea what it is I'm looking for before I start bothering them with questions.

I think I'm going to build the swingarm myself, but I need to decide which carrier and axle I'll be using. The KTM quad swingarm would be the ultimate way to go, but it uses a link shock system and I would prefer to keep the PDS set up as it will facilitate ease of height adjustment as well as simplify setting up the shock. I really like the ATC style swing arms that clamp onto the carriers, but I've never taken a good look at how the brake carrier works on that setup. I also want to make sure I choose something that has wheels and axles readily available.

Tons to think about and learn (we can't all be as smart as Dude) may as well start now.
