Twin engine bikes

[Freud]

Sliger on the dual Royal Enfields and Buddy Martinez with the dual Triumphs each made a mark in earlier times.

This isn't necessarily something I'm going to build, just something I'm interested in.  I haven't seen very many twin LSR bikes.  So I was wondering if it just doesn't work out right and that is the reason I'm not seeing them.

I'm sure you all remember the Hogslayer. Nortons not Triumphs but with the exception of the later rotary Norton, probably the last hurrah for Brit engined race bikes before the rice burners took over.

If you want weird without the LSD, how about this. 2 supercharged 1000cc Ariel Square 4 engines in a vintage GN chassis used for sprints and hillclimbing.

Neat!

I was searching for twin Trumpet pictures yesterday and came across a thread on, I think, dragbike.com a drag bike from the '70's or so that had two Ariel Square fours!  That was wierd!!

Slopoke, that was a great search. I was there when he ran that pass. Buddy Martinez was the next to run and he went faster than Sliger

but Sliger was the first.

Ok, dream along with me...
Twin 1953-5 Triumph Tiger 650s, running in A/VG.  Bored, stroked, carbed, ported, cammed, blah, blah, blah..

OK; I'll dream along with you.
A double engined Triumph, you say;







Dübble Trübble !....well that it's name

Flipping love it. Gotta build one some day. For some bizare reason they facinate me.
Have a small collection of twin-engined bikes-pictures.

A few other twin engined Triumph










..a double Jap salt bike;



and a HD:



and another HD salt bike

Last year at Bonneville BUB Speed Trails:



...and from BUB as well;
yeah I know it's streamliner but it deserves a mention anytime;
the mindblowing brilliant double supercharged 2 x 1500cc Vincent engined
streamliner by Max.
You have GOT to come to BUB, just to watch and listen to this monster :



...the sound alone can make grown men cry....with joy!

What can you tell me about Pat's bike?  Any idea where it is now and any history on it or on Pat?

I know his daughter and she would love to know some history as her Pops passed a few years ago.

I wish I could help, but I'm afraid I can't.
The only info I have is what one can read from these bits

Sorry  'bout that.

One could, if so inclined, come up with a nasty joke about twin handed..........naaa, never mind.

[Kansas Bad Man]

Calkins I have no idea what your goals are or if you are truly dreaming;

Ok, dream along with me...

Is it worth it now?  With such a small engine size, would the extra weight make the idea not worth it?  I haven't looked yet, but I would think that you should be able to get 750cc-900cc out of each.

Is vintage gas your challenge?

Do you just want  answers that will never be used?

Do you really want some speed for your financial investment?

Do you want to use up a bunch of the existing Triumph parts?

Denis Manning gave up on English twins about 30 years ago.

Contemplate what Bob Leppan did in the '60's.

If you want a good ride with less complications, go to the wrecked bike shop, buy several 600 cc Honda, Kawasaki or Suzuki engines and leave them alone.  Make your build around them and concentrate on your chassis. You will get more bang for your buck. If u ever decide to turbo them there is more equipment available than the Triumphs could ever tolerate.

Before the Manning, Akatiff and Wheeler skirmish developed, Don Vesco told me, "there are production engines available that have a warranty on them" that would raise the 318 record. Keep it simple and have fun.

Bored, stroked, carbed, ported, cammed, blah, blah, blah...

Todays stockers from a salvage yard will outrun all that expense and probably one of those engines will out perform vintage twins. Besides, with a single engine you don't have to contemplate syncro between two engines.

But on the other hand, you can attract many pipe smoking, grey beard stroking men that will talk all day about their Limey bikes they had in 1955

Where the h e l l did you get the LSD?.

...and here I was thinking I was going to go fast with 60 year old twin engine English iron..  Thanks for straightening me out.

Silly me.  I should have known better.

[Freud]

MAX.....it all applies to you also....except once again, passion rules.

You will just live with it and make a lot of people, with similar dreams, very happy.

Now get back to work.

Stainless needs something new to post.

Avoid the pipe smokers for they can shorten your life.
