Yep, I only made one but I still have tooling for all the plastics that I vacuform. The frame fixture is another story. I made a minimal one that wasn't worth using again, just to try out my frame design. I would have to make a better fixture before building more. But still, anything less than ten or so presold would not be worth the effort.

. . . 10 (or so) is a bit beyond my budget, but it has got me thinking. LOL 

I confess there's a part of me that want to do a small production build but calmer minds prevail. Could I be , egad, getting older? Smarter? Nah....I'm staying busy babysitting this RR bike. Its faster!

 I am wondering if anyone has updates on the various e-trials R&D efforts? Is anything full sized with a clutch other than the EM realistically coming to market anytime soon?

Yes and no.  

Yes: The Yamaha TYE

No: I do not know if its available.

Hi,

this is matze,

i try to convert my gasgas to a e-Trial with wet Clutch. would be nice if you can help me a Little with your Expertise.

So I take it you intend to use the stock gearbox as well as the wet clutch?  What motor are you intending to use?`

 

 

i just try to get everthing in.

i use a hpm5000b 5kw goldenmotor engine. only the Clutch of the gasgas, modified. i will Need to do a cnc case for housing. no gearbox. i tried, but it is not enough space in the Frame.

i orientated at the EM race 2020 with Clutch and flywheel

Looks like a nice little motor. So you will use the small primary drive crankshaft gear keyed or splined to the motor shaft , then to the stock GG clutch, right? Then make a inner and outer case with the bearings for the countershaft, correct? You will need an oil seal on the inner motor shaft and on the outer countershaft. Is that the plan?

I would be concerned that without a gearbox, if the motor KV and your reduction, primary and secondary combined is not low enough, dumping the clutch will be like dumping clutch in 3rd gear. Or whatever. What I'm trying to communicate is that with a fixed reduction, you have to pick a realistic top speed but if you do that, it would likely be geared too tall to have any decent clutch launch. I tried this with and was like, oh! I didn't work..... Here is my direct drive GG conversion I built before I made my own.

Reduction is 27 teeth in engine to 75 teehth on Clutch,

Schaft on Clutch is than 9 to 48 in wheel. 

Frind of Mine Drives Same Gear Ratio without Clutch with Same engine. It is OK for riding. Ratio can ne adjusted with sprocket.

 

Well, I hate to burst your bubble but it really doesn't work like you are expecting unless you have low first second and third gears. Also, its worth mentioning that the GG has a roughly 20 pound flywheel for inertia when you dump the clutch, the flywheel effect,, so the inertia of your smaller motor is quite small, which further reduces the 'big hit' you want.

If it were mine, I'd definitely use some primary reduction, chain, belt, gears, whatever. That smaller motor is likely a high rpm motor and needs reduction, but I would not use a clutch without gearbox.I tried it. It sucked and added weight. Unless you are a high level rider, its just fine without a clutch once you dial into it.

Some people make an electronic clutch, which I also made and didn't like either. Its a potentiometer that sort of cancels the voltage from your throttle.

My Setup ist Like the EM Race. Flywheel will also come on Motor Schaft. I will try. Would bei cool of you can send me the CAD of the GG frame. 

There is a primary reduction. !
