Left-hand drive Bantam / 4-stroke Bantam
« on: 19 March, 2024, 20:29:06 »
Hello all

As someone who spent many years riding left-hand gear-shift bikes (and of course, by implication, and more importantly, right-hand rear brake pedal), I find that I can't adjust to the 1963 D7 that we have. Perhaps in time, a long time, I might, but it feels unsafe to me, and so it puts me off riding - the worry of instinctively trying to brake with the gear lever in an emergency etc.

My question therefore is, what are the options ?

It's my understanding that the original DKW would have been left-hand gear lever. I imagine that re-engineering the cases etc to adapt would basically be a non-starter. So that leaves an engine swap. I rather like the idea of a 4-stroke, just because it would save mucking about with 2T oil / reduce pollution etc, but a lot of second-hand Jap parts (e.g. engines) nowadays seem absurdly over-priced.

I did wonder about the possibility of something like a CZ engine.

Does anyone have any experience with doing any of these things ?

Thanks in advance. Apologies in advance to anybody out there outraged at such a proposal  :)

RB

It is possible to engineer left hand gearchange.⁸

Hi RB,

Are you still riding non-British bikes?  If not then you will adapt and the more you ride the quicker that will be.  It is always possible to swap things over but it may look a bit untidy and with linkages there is bound to be some slack in the movement of the controls.
If you are considering a 4 stroke then the nearest in the BSA range is the 250 C15.

Dave.

Some trial Bantams have both the gearchange and the brake lever on the right, usually by converting to a cable operated brake.
With some skill I seem to remember it is possible to exit the gear change shaft through the left hand side too.
Or fit a Honda 125 engine, it’s been done before, (Not sure what this does for the registration docs though!)

Wotcha.

Having a left foot which no longer works ( blind car driver's fault ) I can only ride bike with a right foot gear change.
So I did it the other way around - engineered a right hand gear change.

A riding mate bought a Chinese or Korean engine unit complete with carb for a little two-stroke French bike from the 1950s that he was building. It was on Ebay and he got it for something like £75. It had been used but it was complete with starter motor and ran great. Could be an easy swap (and four stroke) in your bike, but why not persevere with the engine you have?
Probably most of us have/still ride a number of bikes with both LH and RH shifts so it becomes easier after a short while.
BTW, make sure you have the V5C before doing any engine swaps..

This Bantam is for sale on Facebook. Some serious changes but shows that the gears can be made left foot operated.
