440 Cubic inch single cylinder cross head two stroke. 20 horsepower, at 400 RPM. Weighing only 5,200 lbs.
10,000 hours (That's over 12 months continuous) between oil changes
200,000 hours between re-ring.
Typical sevice life - 40+ years
Most parts still available.
I'm pretty sure I could get 3 more HP out of it with a tuned pipe, but the pipe would be around 36 FEET long
What's the bore and stroke on that one? Sounds like it should have a piston the size of a small ship engine.

7 1/2" bore, 10" stroke. Cast iron piston (and nearly everything else). The piston and connecting rod weighs about what an airhead engine weighs. Enormous cast iron beasties amuse me.
The flywheel outweighs TWO /5's.

The Africa Twin (Transalp) 52 degree V-twin gets my vote. Show it respect and it should take you RTW.
Ok...it's broken here on the bench with a bad output shaft bearing but I attribute that to poor chain maintenance
...by the previous owner.
Having split the cases on it I found it very simple and uncomplicated.
As for my airhead gspd...well it's a tough motor, but geez it sure has alot of shit that can go wrong.
You have to 'keep up' with the airhead I have found and it will also take you far.

I'd vote for the late 70's and early 80's Honda inline twin, there is many version and they are as strong as a stone, as long as you keep if sparking.
Can't vote for my actual VTR1000 engine, the CCT's killed many engines from chewed ex valves.

The toy 22R is known to spit headgasket, I liked the Accord`prelude 1.8 to 2.0 I4's, had two, no oil burn after 250 k miles, Cast iron BMW sixes, most old Mercedes and Volvo engines, Nissans I4's specially Datsun 210

The BMW K75. When the electrics go they're a nightmare, but I've seen K75's and K100's with about 300k miles on them, and all they needed was batteries, brakes & oil changes. Apparently the "middle-years" are the best.
Don't let them sit though...pumps & filters get pricey.

Follwed by the Airhead. Points are better (pre-can) followed by the later electronic ignition. My 150k+ mile, Katrina flooded R65 hummed along to Biloxi & back yesterday (I wanted to go to the beach dammit!) with little difficulty.

Followed up by the later nikasil barrel Guzzi. I've seen too many problems with the chrome bore jobs to like them. Someday I'll have my SP back up & going from it's "refresh"....(yeah right)

You can keep the Hondas, thanks.

Oh, if we're talking car/truck motors:



The Dodge Slant-Six all the way.

Any of the Honda 125 or 150cc stepthoughs used by the millions in Asia. They go anywhere and go forever. They regularly carry families of five, mountain-high piles of chickens in baskets, pigs, or whatever, so could easily take a set of panniers and a big carry rack. And the damn things never seem to wear out.
If you get the Astrea Supra X model, you get disc brakes and all!

without doubt BMW's M-30 6 cylinder motor in all displacements. 2 valve motor-sohc.

I've seen these go 500,000 miles and crosshatching still on the bores, heads never been off etc.

Pre-'81 heads had thinner water jackets-later ones ARE better-a direct bolt on.

Extremely overbuilt-forged crank, rods and sometimes pistons.


I'm going to put one in a small boat with a jetpump off an old waverunner-stay tuned!

Re Land Rover; Somebody who should know once said to me,
"The reason the Brits don't make computers is they haven't figured out how to make them leak oil." I don't know about the older ones, but the new ones are castrated yuppiemobiles. Get a Toyota Land Cruiser.
The 22R has become one of the most ubiquitous and has a very loyal following. I imagine you can find one anywhere.

I assume this is a question regarding travel? It depends on what country, but harley left a lot of 45's laying around when they left years ago. Many are still going. The other would have to be a Hinda step-through. They have sold BBBBillions of them all over the world. If you can't get parts for that- walk.
