1) Mechanical inline reverse box
2) Electric reverse "home-brew"
I'm not aware of any off-the-shelf electric reverse mechs. I think STM sold one but it was fairly home-brew IIRC... (ie in constant
development)....

Hmm, my gearbox came with reverse. A Ford type 9, and the Toyota W58 going in has reverse as well.
Why not use a box that has reverse??

How boring are these constant remarks, yawn, yawn.
If you have nothing constructive to offer in a post regarding BEC's why bother posting. Your constant anti BEC is getting very boring. You
don't see BEC owners heckling every post you put up so why do it to posts put up by BEC owners?
AB Performance does a mechanical one supposed to be good quality or there is this one

Because then I'd always be jealous of those with a BEC and would find it necessary to mercilously mock them

Thats better a proper answer , Have you a web site for AB performance.
I fancy the electric route to be honest, all ready got my propshaft, so dont really want another 2 made up for the reverse box route.
This post was meant for the owners of mac#1 and what have they done or going to do reverse gear wise.

Take one bike starter motor and have gear cut in some kind of plastic to match the pitch on starter...mount gear on diff like a space then rig up
starter to either slide into place or have it lowering...
plastic gear will shear teeth if something goes pear shaped and accidently chunks into reverse. go as big as you can in the given space for the gear
and will throw you backwards quicker than you imagined a wee bike starter should!
those reverse box things are heavy and if memory serves me right turn into "oil pumps" and chuck oil everywhere

This is a valid comment, has anyone investigated using a car gearbox on a bike engine. I know many will comment on the weight and complexity of a car
gearbox but it could be an answer to many peoples prayers.

But generally the bike engine has the gearbox built in.
That helps with the power to weight ratio.
To take a drive without the gearbox would mean a lot of mods to crankcase etc.
The last time I saw one without, was on a Triumph pre-unit twin, then there is the American series of twin cylinder lumps as used on American
Chopper.
On Saying all that what does a VW air cooled engine use, that has a separate box

I think he means using a car gear box in ADDITION to the bike gear box. It would be in line with the prop shaft. Take a gear small box (like a Suzuki
Samurai) cut the bell housing off. Attach the bike output to the gear box input. Gut the gears out of it leaving only the 1:1 ratio forward gear and
the reverse gear. I don't know if it is possible or not. Seems feasible. Russ

Me - I have considered it.
I think with the right box it's very much the locost way. Light gearbox is the answer.
More updates very soon.

There was a guy a while ago with a green busa powered seven and a car gearbox. I can't remember the configuration, but there were some videos
posted.

Well, I get constantly bombarded with comments like 'should have put a bike engine in it' but that wasn't the point of my post. It
was abit tongue in cheek I admit.
Reverse boxes for bike engines are ridiculously expensive but car gearboxes have a reverse gear and shift. Isn't about time some one found a way
of using a car gearbox as a secondary gear up or down device with reverse?

A good point, A friend of mine built a JZR a quite few years ago with a Hardly Dangerous engine in it. He mated that upto a Ford gearbox. Now what
bike engine is North-South I don't know.The V-twin looked bang on in a very early Morgan replica.How you go on for a locost style.....
..Which was nice..

I have done just that.
Yesterday I pciked up an adapter from a member of this forum who has a waterjet machine.
Centre spline are the same as a ford small clutch, four bolt holes are the same as Ford propshaft PCD.
Can you see where this is going ?
