I saw my neighbor load his new Polaris RZR UTV in his trailer and started talking about the engine. He told me about 89HP Rotax twin in Can-am outlander his friend has. He said that the engine and CVT only weigh about 200lb total. I had no idea that ATV engines are in that HP

I started digging and found that it is the same engine that is used in the road legal Spyder reverse trike. It has EFI and liquid cooled and makes 100HP in spyder. The Spyder cruises at 4500-5000RPm on highway and based on the torque curve I found online that is about 60-70HP continuous...which to me looks like a lot of gasoline consumption.
Not well versed in ICE, what is the take on using something like this for aviation as is. Are ATV/spyder engine reliable enough and the problem is with the designated ECU only? If the ECU can be adopted from aftermarket, is this a viable route worth exploring?
