Im trying to find a mechanical reverse kit. I have an 89 K100 engine, i think teh transmission is from a K1200Lt since it mates up and it has a place for an electric reverse.
Im building a reverse trike so electric reverse probably wont pull the weight and pushing the vehicle really isnt an option.
If anyone has any information on this please drop me a line.
Thanks

I don't think anything lke that is made. I know that Goldwings and some BMW's touring bikes have electric reverse. I once owned a Goldwing and the reverse worked perfectly. I've seen the BMW's ones work and they are likewise very good.
Your best bet would be to get a machine with a built-in reverse gear: e.g. Goldwing, BMW, new Harley Trike (optoinal mechanical reverse) or Harley solo with Champion reverse (mechanical) and sidecar.
My 2 cents. Good luck!

Thanks. I know harley has it but i prefer teh bmw drive train for reliability and also its lower cg. So i guess i get the harley kit, get teh harley transmission and then try to figure out how to retrofit it...ughh

Oh dear........The BMW is a shaft drive. Anything Harley is belt or chain. I simply cannot imagine how one could adapt an HD transmission to anything BMW. They are apples and oranges.......
no not adapt the hd transmission to a bmw, but compare teh 2 transmissions, look at what the retrofit does for the hd, figure out how to do the same for the bmw.
Most Harleys have the CG below the axle line.
I don't think the BMW K models can make that claim.

The Champion reverse for Harley is now built for the five and six speed HD transmissions. They are a true retrofit since they are aftermarket. There is another company whose name I have forgotten but someone mentioned it here a while back.
The new HD five and reverse is fitted to their trike and is a company-built piece of prime equipment. It won't fit the 88 cu. inch Twin Cam bikes as far as I know.
In my humble opinion, for a person to fit any sort of reverse to a BMW, you should be thinking in terms of buying factory parts that are built for the job. That, of course, would cost a lot, but then so would a home-brewed machine job.
I continue to feel that the stock electric reverse on a BMW would be ideal. If you could get a BMW with the reverse, that would be a very fine tug for your hack. Or, a Goldwing with electric reverse or a Harley with an adapted aftermarket reverse.
I would like to have a mechanical reverse on my Harley but I object to the price. For $1,400 more or less, I can still be very careful where I park and push if I have to. I've seen those kits and there's not much to them.
Then, unless you are capable of installing one yourself, you are looking at another few hundred to get the reverse installed. I am able to do that sort of work but many are not.
I built an electric reverse for my Harley but I need to speed it up so it's temporarily off. I used a winch and the gearing is too low with resulting slow action. I am working on getting more voltage to the motor or changing the motor assembly to something that will run faster. Until then, it's on the back burner.
Happy Trails.
Im using the BMW engine to push a reverse trike, enclosed cabin, so pushing it out of a parking space isnt practical, also the weight, around 1200 pounds. I guess im going to have to find me a really good fabricator for this. Thanks

Where are you located?
im in Kent Washington, just south of seattle.

Don't the Urals have shaft drive and reverse? I understand they're a copy of WW2 vintage bmw's but they may be more adaptable to your application. If you go to champion's website you can see the engineering that goes into their reverse kit, it's basically just a set of gears that mount on the mainshaft and countershaft with an additional gear that's engaged when the bike is in neutral to reverse the output shaft. This may give you some of what may be involved in fabricating your own mechanical reverse, although they make lehman trike conversions for the K1200lt that use the starter/electrical reverse. Try going to a trike website and see if they have problems with the reverse on the BMW's. I'm sure weight wise they're comparable with the weight of your reverse trike.
thanks! ill take a look at it. Ive got electric reverse already but looking at it not sure how well it woudl work is say parked pointing downhill so thast why looking at a mechanical reverse.

Regardless of the type of reverse that you have, you need to be aware of where you park with a three-wheeled vehicle. I don't park pointed downhill with my sidecar.
This needs to be able to be treated like a car, parked wherever.
