Sounds like a great bike but my guess is that if it were in the hands of a pro level rider the cost to maintain it would be brutal.

Seems pricey to me…Converting $9,599 AUS dollar to US dollar is $8,959 US.
Base retail of a 2010 YZ125 in US is $6,090, and buying the 144cc Athena kit directly from Yamaha ($859) = $6,949 before installation cost if you have someone else do it for you. (Or Eric Gorr‘s mod‘s which according to his website is even less expensive @ only $495 to convert your cylinder/head assembly to 144cc).

Obviously not truly the same animal when you consider:

Modified crankcase set
Modified cylinder and cylinder head
Modified L+R power valves
58mm custom made piston (made in Germany)
Custom made piston ring (made in Germany)
Hour meter
Graphics set (front guard, rear guard, L+R radiator shroud)
Carburetor jets

But still quite a price differential (over $2,000) vs an Athena or Eric Gorr modified/kitted YZ125. Wonder what the performance difference would be? Can certainly buy some suspension upgrades, a pipe, graphics, porting, etc. for less than the $2,000 differential it seems….Just thinking out loud.

Hope to see a comparison test sometime on this though.

Cool, what is more interesting though is that Yamaha spits this out despite the two stroke being considered dead! Ha! They saw KTM are making cash on the 150, while their 125 sold less than before, so VOILA!

They produce whatever we are willing to buy, it's as simple as that.

Noo more than a 125 has ever been right? I think this is a positive step in the right direction and seems Yamaha is testing the waters once again to be ahead of the curve of the big 4. This is exactly what us 2 stroke guys hvae been hoping for...... bravo Yamaha for giving it a chance!

Have you ever had to rebuild a four stroke motor before? Im sure 2 grand on a four banger is significantly more expensive then $600.00 on a top end for a two smoker, give or take a clutch here and there.

That all depends on how much that custom piston and ring cost. That bike in the hands of a pro level rider would need a new ring after every weekend of racing and a piston every other week.

how often does a 2 digit pro change a 4 stroke top end?
i dont have to wonder about a 2 stroke knew enough low 2
digit pros to know that info. but i am wondering about the 4
bangers.

You are not accounting for the fact that we get raped in Australia when we buy new bikes. "Here is your new 450 mxer sir, that will be $11500AU and I will need you to drop your pants & bend over"

If you're gonna spend big bucks on a big bore YZ125, I think I'd go all the way to a 167 kit from RPM/Maxpower. It is a bore and stroke kit, but you gotta swap out the cases for the 144 anyway. Might as well stroke it while you got the crank out. But that's just my thinking, which, I know is flawed. My wife tells me so.

It would be kind of hard to get away with running your 167 in a 150cc class, which was the purpose of the YZ144.

If it's one of the top support team bikes, it would be every weekend. But there are two digit guys that can go an entire supercross on a piston and ring if they had to. Outdoors would be a different story.

Much less maintenance on the four banger for a mid to back of the pack rider.

Thing is Jim, when a thumper lets go it often fatal for the whole engine. 2 bangers are a snap to fix up. Having said that, I do hate cleaning powervalves etc on a regular basis. All my thumpers, except for 1, were virtually maintenance free save for oil changes and cleaning the air filter. The one that did let go would have cost about 2 years worth of 2 smoke work if it wasnt under warranty.

Your wife's right too, I know cause mine says the same thing and she's never wrong.

I have been involved with four different teams and it was fewer parts and less maintenance on the four bangers.
