Does anyone have some advice tips on installing a bmw on an areos 2.............good /bad points things to look for thanks tom

I've been flying a Beemer for better than two years now what are you lookig for?

There are many BMW engined trikes here in France. Most have the later oilhead engines, 1100 and 1150 which go from 85 to 99 hp. The hex head engine, 1200 is also fitted to some but is de tuned to 100 hp. I think the main problem is getting a gearbox for them. The 1200s are all twin spark and the 1100/1150 can be either single or twin spark. They are all fuel injected. If you go to http://www.powertrike.de/Motoren/BMW/index.html you will see a twin spark 1150 fitted to a trike, this is 95 hp, but the R1100S engine is 99 hp. Google "take-off" and you will find a German company who makes gearboxes.

Hi Tom,

I am also planning to put a BMW R1200 on an Aeros 2 trike.
I have the engine already and bought the german Take-Off gearbox/cluch for it.
The Take-Off gearbox looks good and reliable and has a good reputation here in Europe. Expensive though.
I will use the BMW stock engine control.

The gearbox is a little different for r1200 and R1x00.

I am thinking about how to keep the exhaust/intake pipes/voulumes similar to bikes.
That is difficult. Changed exhaust/intake will give less air to the engine => less power and higer fuel consumption. The BMW R1xx0 have _very_ good fuel economy.

The R1200 has higher compression/knock sensors/should run on premium fuel/is lighter/ has balance shaft/ vibrates less. But R11x0 is also very good engines.

The dual igniton on R1200 and late R1150 is not really what we think of with dual ignition. It is mainly used at low power to get clean exhaust gases.
At high power only one spark plug is really used because the timing of the other is so much advanced that I suspect it can�t be used for saftey.

I plan to make a custom made display with engine data extracted from the engine controller via the CAN-bus.

Mel, if you have some detailed high-res images of your BMW installation, that would be very interesting to see:)
