wahoo the smokers are fighting back 

Bottom mount Push rod engine. HIGHLY doubtful to be used in a motocross application.... but hey... if they make 1 why wouldnt the make others?

Talk about a long stroke!!

Love to have a EFI CR500!!!! I'll buy two if they make them. :-)

The Fact that Honda is working on a two stroke made my heart skip a beat

Cam in block, pushrod, 1V twostroke.  Looks like an old railroad patent.

its a prank .....it looks too 1950s

it could be done wihtout the top valve. Like the cr500fi on youtube

Honda hates 2t.  They'd use it for garden implements.

So much for the "simple" 2 stroke engine.

I don't see how the fuel goes thru the reed assy, lubes the crank, etc, then goes where?fuel mix goes up to intake port, or...? AND the valve is used for what, straight gas injection, or.....? I understand D.F.I. technology, but im tryin to see how it lubes w/oil on bottom, and injects fuel on top, therefore gas burns and oil mostly lubricates and doesn't "burn" in the traditional fashion.....

Im waiting for Bombardier to make a high perf 2 stroke for the cycle industry, THAT would kick-ass!! They do it in their ski-doo sleds, (E-tec d.f.i. )so watchout........one day maybe.....into bikes!!!

fingers crossed​

Notice the flat "foot style" mount. Same as a powerplant or lawn equipment engine.

I think this will use an oil pump to lube the engine like 2 stroke detroit diesel

where can I learn how it works?

Without an expansion chamber how will we know if it's a two stroke in photos!?

I first worked as a mechanic in a Honda shop in 1965.   Early on, it was clear that Honda made a really excellent product, especially in those dark days of Lucas electrics and oil leaks.  I don't presently own a Honda bike, but will always be a Honda fan and am thrilled to learn they are moving into developing an emissions-compliant 2-stroke engine.  If anyone can "get it right", it's the folks at "Big Red".

Bravo, Honda
