That's with a 130cm prop. On paravol.info I found a link to a chart of real world thrust figures which I've attached. If that chart is to be believed, a moster with a 130cm prop makes between 74 to 78 kg of thrust. So this eos 150 has about 5% to 10% less thrust. It also weighs less, and if the fuel consumption is lower than the "thirsty" moster, plus reliable... Also, eos' 4 stroke is due to be released this year.
On a side note, on 27 Nov 2013, Miro Svec of Scout paramotors toured the eos factory in Austria and remarked
They have engineered everything from scratch without making shortcuts or sticking to common patterns (most engine manufacturers actually use the same Italian pistons and cylinder heads). The EOS pistons are from Japan, the cylinder head from Taiwan, different carb, different airbox, clutch…These guys did everything to keep the weight low. http://www.scoutparamotor.com/review-of-the-new-eos100-light-weight-paramotor-engine/
