I think it's a result of BMW : 1 - 2cv : 0

Is it? because it's GS and it's failure of flywheel, which could be bad craftmans ship or failure on the beamer bolts? Twisted Evil

It was wednesday at the "Trophée d'Alsace" race. Maybe the too light flywheel broke... and damaged disc brakes but also injectors... Car started to burn on the side of the track !

I heard that BMW engine needs wild 7cm spacer between engine and flywheel
when fitted on 2cv/GS box. That is one thing what makes me a bit unsure
about this setup.

Very interesting topic! I guess that the test drive is fantastic in strait lines... But in the corners Confused

It's only 10kg heavier than the original 2 CV engine. So I guess there are no probs in corners neither.
I know some dutch guy driving BMW powered 2 CV as well.

But the 2cv is very heavy for a Bike engine (no torque) at least you're using a car gearbox, cause Bike ones on heavy cars I've heard are rather strained after a while.

Must be very cool to drive though, I'm quite certain that Bike Engined Cars are among the funniest things to experience on the road

Most motorcycle engines have more torque then a 2cv, problem is gearbox. BMW has more then enough torque, optional a guzzi engine is also perfect (Guzzi engine was designed to be used in a car). Then off course you could use a harley engine. The reason why you would use a 2cv / GSA gearbox is because you need a diff. BMW is rear driven, no diff needed there.

By the way, my suuz GSX750F is 106HP and with 70NM torque, aircooled. But problem is you have to buy a seperate diff that can handel 106HP, quite expensive.

yep, but where is the torque above 2cv torque on a bike engine ? 6000 rpm ?

useable torque is nothing like in the same ranges between a car and a bike.

My car has 1000cc R1 engine with 160 HP.

taking off smoothly with it is crazily stupid and can become uncomfortable, because there is no torque below 4000... the car only weighs 400 kilos but that is already twice the bike weight.

But true, this goes more for RWD cars that use the bike box. Here with "2cv" box the strain won't come so much from the weight of the car, but from the power of the engine. Whereas on a RWD car strain on the motorbike box and clutch used will come from too much weight.

But at the end of the day, whatever was in the car originally, it becomes a car shaped motorbike, so weight is a big issue.

R1 has not the same torque as BMW or Guzzi engine, you cannot compare them. BMW and Guzzi are low rev engines with high toque at low RPM. Remember that BMW and Guzzi have flywheels, something your R1 has to do without. Fit a flywheel to your R1 engine and torque at low rev will improve enourm, but throttle response will be much slower.

Also remember that BMW en Guzzi engines where used in cars in the beginning wheighing around 500-600KG

True, I'm talking race engines

And I do like having 12000 Rpm to play with Laughing

Knowing the Guzzi engine of my 850-T and comparing it to the BMW-engined R100RS I once owned, I would definitely opt for a Guzzi engine for purely sound aesthetic reasons - a Guzzi can easily be made to sound close to a high revving tuned V8 while a BMW engine always sounds like, well a BMW engine... But that's just me.

Either way - in both cases there is plenty of torque nicely spread out and accesible already from low revs so that won't be a problem I think.

And as inspiration - here is a little ad-hoc video I made. Please excuse the "unsteady-cam"...
