I love the way the Build is going
We need another video on this bike😭
That triangle under the seat looks really nice.
Your channel is so underrated. Keep it up bro. Looking forward to seeing updates on the corvette(s) as well!
Brilliant design concept 👍Alan Northern Ireland.
860cc upgrade will be super nice!!!!!!!
The angle of rear shocks will change the pivotal movement of the swing arm. Leaned too far forward could make the swing arm very difficult to move.
Love the idea of 'triangular' shocks joining the swing-arm. However, thinking about the pivot points for the shock itself, they would both normally be set at 90 degrees, therefore able to tilt up and down freely. Changing that angle to anything but 90 degrees (about 65 in your case?) - I'm not sure it would provide free movement around the fitting, as it wants to move in a straight line up and down, but being at an offset angle would cause it to bind. I'm purely guessing at this, but it's something I would consider if I were trying this method. Lovely work as always bud.
that's a really cool idea for the suspension. i always wanted to build a suspension with longitudinally horizontal springs like the desert racing trucks use. that converts any down force into forward momentum rather than straight line rebounding force as in a more vertical spring setup. makes for a softer suspension feel, and a lot less "bouncy" ride.
Great idea!
Like that development!!!
great job Taylor lookin good so far
Sweet. I think you will come up with something that will work better than you need. That's why I like your show
The Canadian Yamaha RD350LC had a monoshock used for many RD conversions. I doubt you would want ride height adjusted with swing arm geometry. The big design trick is the desireable straight line between the front of the shock and the rear wheel. Lay out on paper your components and their arcs and play with the positions. It’s only ideal in one position so you have to mount it so that that shock’s rear mount never drops below the center of the straight line as the pivot arcs. You don’t want it swing past center when fully compressed. Not hard to do at all but the closer to a straight line the more direct acting the shock. If that angle changes a lot you have a variable spring rate and some have even gone over center and gone inverted in the rate. Eyeballing will show that movement is not that great so much of it is theory but you just don’t want to start with theoretically incorrect angle. As for double shocks - that might look cool but is mixing the negative compromises of both setups not to mention extra weight - not only to the sprung weight but also partially to unstrung rate. Theoretically, the shocks, if not in plane with each other, would need to be able to pivot on heim joints as the angle is changing in two planes with swing arm movement. An awful lot of potential for undesirable handling. I’m no engineer but these thing come to my mind anyway.
Check out for the bold in the UK I am sure he is doing a double shock rear end
Yep, on the mongrol build
@@kihestad Great to see how regular home DYI builders follow/get ispiration from each other. ForTheBold inspired me a lot with his cafe reacer builds, and showing that is possible to achive good results eeven with a tiny garaje space.
@@1Poe Absolutely! A lot to learn from others, and sometimes just for inspiration or entertainment! 👍
nice one, this video! looking forward to the next one!
Looks fantastic. 👌
This build is exciting!! hehe good luck
Might I suggest mocking it up in a 3D cad model. Binding and angles should become more obvious as you put it through it's range of motion. I work in Solidworks but I'm sure there is cheaper software that has some of the same functions.
Twin shocks in that configuration were I believe used on vincents
Mono shock. Less weight and less visual bulk under the seat. A rigid mount is what you want.
Try looking at Norton commando fast back rear tail section to finish off the rear mudgaurd, fender in your lingo
There's a reason why Phillip Vincents 1930's and Yamaha's 1970's cantilever designs are no longer used. And both designs used a rigid rear triangle.
Very cool. I just stumbled across this build but will be watching from now on. It looks like a lot of fun , thx ☺
Great work! I love the look of the subframe you did 💯💯
Wow! What an incredible and fantastic job so far - it's coming out awesome! Can't wait to see what you do with the rest but I love the ideas so far!
Rear suspension seems similar to the kineticmotorcycles Honda cb monoshock conversion, should look really clean when you get it all dialed. Loving the build. Keep up the good work.
Super nice 👌🏻
Love this build
Looking good. For some reference on double shock type “mono” systems look up KSI Knobby shop International Thumper 1977 Marty Moates. There’s a couple other dirt bikes that did this. Kramer made frames like that for Maico. In the 70s everyone was trying to catch up to Yamahas system so lots of shop built Motocross bikes with the two shocks instead of one but a mono swing arm
Consider a pivoting transfer link for the top of the shock, sir
Mmmm Siebenrock purveyors of all things trick for older 2v Boxers
I would go mono shock under the seat, I think twin shocks will look too cluttered and almost every cafe racer/flat tracker has twin rear shocks.
I think the bar height is perfect. I wouldn’t go any higher. I like where your head is on the suspension but I would stick with one shock. 2 seems like it’s just forced to get something different 🤷🏻♂️
Taylor looking good, question though. Is that shock mounting position going to be in the way of other maintenance on the bike? Also I don't know that you will have the right articulation in the swing arm / suspension when cornering. Not positive but it could be an issue. Looking forward to the new videos!
Your design for the suspension sounds really good but I think you may encounter a lot of problems getting the adjustability you are looking for. The bike is coming on really well and I love the look !
I haven’t watched in a while- will try to catch up.
Nice work, super creative.
Man that looks sick
Check out the Janus halcyon 450 rear suspension
I saw a monoshock conversion similar to what you want to do, where they removed the airbox at the back of the engine and made a custom curved plate to make more room for the shocks. Look up Wilkinson bros 1976 r/75/6. I think this would give you more room to do the two shocks and let you adjust your angles more to get them how you wanted.
Plus it would give you another feature to incorporate with the design of air filters you want on the carbs
Great design love it👍👍🏍😎
I think the brace for the seat would look better if you made it so it formed an equilateral triangle?
haha big bore kit, nice.
I think the guy that runs For the bold u tube channel is running twin ( mono?😂) shock design for that tho u really need. Much weaker springs a radially slotted plate with two fixed side plates and a good sized bolt hole to lock em together would do the the truck for the forward mount on the adjustable brace / mount it won’t have a lot of side load on it because of the swing arm pivot
Hey Taylor. Names Nick just got into the cafe bikes I’ve watch led all your episode. You do great work I have a couple of questions. What are the names of the batteries you use in your boxes
Hey Taylor, what’s going on with the Airhead?
Hi i think it would look better with twin shocks more classic look for a boxer
Vincent Black Shadow type suspension?
If one will do, why mount 2? 👍
If you want some tips about suspension from a BMW customizer pro. See the following vid. ruclips.net/video/GcNMtE5fs24/видео.html. He also have all kinds of BMW mods.
any update?
Where's the end result??
check out For The Bold on YT...he has done a double suspension affair with a swingarm he made...if i am understanding what you are doing.
มอไซค์ ไต่ถัง.
Think it looks cool with no fender but practicality would prob be terrible. Be more of a chance to have rock and debris hitting your back when riding.
Man, looks like you want to overengineer something simple. Will it look cool? Yup! Will it be practical though....
???????
are the pillion pegs on the swing arm??..better get rid of them
Any updates on this build?
The lines on this little ripper are coming out great, man.
Nice, clean solution!
Hi Taylor, great looking bike. Loved your wiring videos too. How about a welding tips and technique video.
Great job on the subframe. Anxious to see the final rear suspension!
love the shock idea, never seen anything like that with a doubled up swingarm! go for it man
You can always use bar risers and or different handle bars
You might want to check out a Suzuki gs project that Craig Jones is building at Doghouse Customs over in the UK shaft drive mono shock. He is on RUclips
Gragas Jones is ( Dog house customs )
Great job on the sub frame!
