Hello from France,

I've heard OS is going to release a new engine certainly called .12 TzR.

Main features :
- 2.1 cc
- 3 ports
- 16% nitro design
- long stroke ( like italian brands )
- 12mm crank shaft
- new case ( the case of the 18 TzR )
- new carb
- new agressive machined piston/sleeve
- Ifmar legal version and Efra legal version
- why not an OS Speed Division engine?? ( I dream....)

It will be presented at the Nuremberg Show on february.

Do you have more info??

hello from france,
thx Benny.

I will be able to present inside pics because , I will receive my engine in 10 days.

Very big engine, and the price will be near .12 Tr R-spec...
Available probably on March
enjoy OS

Hi romuald,

Great to know you will have the engine soon, still not available (no news) in US.

Do you know this new engine whether is using a "big neck" carb, (same look as TZ18, can use Nova type air-filter) or just same as past production?

I will buy one later.

hello , I will receive a pre-production engine.

The cranckcase will be black ( alu for my engine), and reinforced like Nova or sirio.
The car is new: big air filter, 3 screws, black treatment and OS Reliability
Long stroke, new piston/sleeve, new cranckshaft, new conrod....

Full new in fact and especially designed for 16% nitro, but 25% also.

Os will produce new pipes and manifold for their engine for big performance...

Thank you for detail info........... ........ I must buy one later!

Hey Romuald, YGM.

Any spec on this motor yet? If it's rated anything above 1.4 or better by OS, it will be a killer

please post pictures as you receive it, I almost went for the tr r spec but knowing that the tz is coming out, Iīll wait and letīs hope it has more power than the tr, 1.4 and up!

So, are they saying it will be an improvement over the R-spec? I plan to stick with my R-Spec for now. Just wondering...

sure, there will be a big big improvment..

Awesome.

wonder when they will start selling it and the price range. couldn't wait to see how the new carb. works.

I wonder how much improvement we're talking here. I'm all in for a new engine (under 200, if possible), but it has to be able at least hang with the many Nova S3 based engines they have out. I've been eyeing the RdLogics, Sirio and Mega line but haven't committed on anything yet. I love the numbers the .18 is making, but it is a bit illegal, so that's out.
