I’ve been to a vintage event, where they had oldish (though I rememb er many of them when they were new) a nd unusual things.

Like a tricycle. I associate these with kids, but they have them for grownups too.

Here we go.

Let’s learn a bit more.

Now let’s look a bit closer.

Yes, that’s the selector lever from an automatic vehicle turned through 18 0 deg.

When you’re fitting two reasonably widely spaced rear wheels to your trike it’s best to have a differential and a straightforward way of doing this is to fit a transaxle. It’s easier to use an automatic one because it avoids th e problem of having either a hand operated lever working through a H gate, or mak ing up a sequential arrangement. However if you want y our fwd transaxle to drive astern you’ll need to turn it through 180 deg. This gives rise to the interesting situ ation where you now have one forward gear and four reverse ones. So how did the builder get around it?

Most Honda FWD transverse engines rotate counterclockwise, therefore a transverse gearbox turned 180 º would work correctly with a clockwise-rotating engine - as it is the case with that V2?

I remember reading the transverse CCW rotation of old Honda hatchbacks actually helps when driving in the wet.

That’s what I had thought, the Harley engine would drive the gearbox the “wrong” way around, so I asked the owner and I think he said he had sourced parts from a 4wd Honda and whatever combination of parts he used enabled him to reverse the rotation between the gearbox and the wheels.

Actually, thinking about it again he pointed out that the H arley is driving through a belt which is on th e left side. The Honda engine would also be on the left. So I’m guessing that th e transaxle is actually in its original orientation, not reversed.

I’ve thought about it again and realised that the gearbox hasn’t actually been reversed despite moving to th e other end. The Harley engine drives the left side of the box just like the original Honda one did. That’s the odd thing about Hondas and the reason why that particular make was used.
