Why use SILLY terms like "Not Emotionally Invested"?   There's not much NEW technology in a Rotax.  More of a different approach. Part water cooled.  Pressed up crankshaft. Weird oil return system Awful carburettors in a bad position, Expensive Bit's. Nev

And yet despite you constantly pointing out all the design faults they are am extremely reliable and fuel efficient engine.

All true, but it makes a bucket load of power for it's size, burns little fuel (comparably), will make it's 2000hr TBO with basic maintenance and just works consistantly and reliably.

Take in all the above and it's no wonder it's being copied.

I hope Zonsen do well. We run a couple of industrial aluminium saws sourced from China, they are now 9 years old and have performed flawlessly.

if Zonsen do good - it can only mean good for any person buying an engine

 

Rotax might start to see any compartive engine ......................... as competition

I do not have a problem with Zonsen (previously Zhongshen).

They have produced millions of small motorcycles and are an engine supplier for other motorcycle manufacturers including piaggio.

They appear to have started in 1982 and are a conclomerate of 52? companies with approx 20,000 employees.

 

Aviation engines are a different market where reliability is critical.

I need information in order to make a purchasing decision. Why would you not give it to me?

Zonsen have exceptional engine test facilities at their manufacturing and assembly plant in Chongqing. The majority of their engines have gone through the accelerated testing process required to obtain ASTM approval.  So they’ve already essentially done your test.

That is great to know... now a few independent market end users need to perform the same engine on stick test and publish results. If the results are closely similar to factory, great. If they are wildly contrasting against published manufacturer results then somebody is probably telling fibs, or the test environment inputs are dramatically different.

 

ChongQing is a great city. For a wild experience take a motorcycle taxi across town; first 30sec should be enough time to get the adrenaline pumping 🤣🤣🤣

My father lived there for 9 years. They lived on a hill and when he went on the local bus the driver used to  coast down the hills in angel gear.😁

And the same bloke probably assembles Zhonsen engines (or Zongsheng, or whatever name it is, this month),  in his off-hours, when he's not scaring bus passengers out of their wits!

If you’re really that keen to find a Rotax alternative, there’s three ship loads of them heading down the east coast, about 160nm east of Hobart at present.
 

Apparently they’re in a celebratory mood letting off a few crackers and sky rockets left over from the year of the snake celebrations.
